The benefits of using anti slip tape
There are many benefits to using anti slip tape. This type of tape can help to prevent accidents by providing a much needed grip on slippery surfaces. It can also help to protect against wear and tear, as well as making it easier to clean up any spills.
The application of anti slip tape
What are the selection criteria for anti slip tape?
What is the working principle of anti slip tape?
The application of anti slip tape
There are many different types of anti slip tape, each with their own unique properties and benefits. However, all anti slip tapes share one common trait: they all help to keep you safe from slipping and falling.
anti slip tape is typically made from a variety of different materials, including rubber, PVC, and even metal. The type of material used will usually depend on the specific application for which the tape is being used. For example, metal anti slip tape is often used in industrial settings where there is a lot of foot traffic, as it is extremely durable and can withstand heavy wear and tear.
The rubber and PVC anti slip tapes are often used in residential and commercial settings as they are more forgiving if someone does happen to slip and fall. These types of tapes are also typically much less expensive than their metal counterparts.
No matter what type of anti slip tape you choose, make sure that it is applied correctly in order to ensure the best possible results. If you are unsure about how to apply the tape, or if you have any other questions about its use, be sure to consult with a professional before proceeding.

What are the selection criteria for anti slip tape?
1. When purchasing, check whether there are burrs on the surface of the anti slip tape.
2. The adhesive should be strong and durable, waterproof.
3. Check the anti-fouling ability of anti slip tape. This material has strong wear resistance and excellent water absorption function, so its application range is extremely wide.
What is the working principle of anti slip tape?
anti slip tape is used in the coating process of double-sided adhesive tape. When the double-sided tape is pulled out from the coating machine, it needs to be guided out by rollers. If the surface of the guide roller is not specially treated, the adhesive will stick to the roller and affect the Production and tape quality. The surface of the roll is usually covered with a low surface energy material to prevent sticking. This single-sided non-slip tape is specially designed for this application. It is coated with a durable adhesive on one side to firmly stick to the surface of the output roller, and the other side is made of special low surface energy rubber, which can effectively prevent the adhesive from being damaged Adhesive effect.

From Pulp to Roll: Understanding the Manufacturing Process of Toilet Paper Machines
Toilet paper is a ubiquitous household item that we often take for granted. However, behind every roll of toilet paper lies a complex manufacturing process that involves specialized machines. Understanding the intricacies of toilet paper machine production can shed light on the journey from pulp to the final product that we use daily. In this blog, we will explore the key steps involved in the manufacturing process of toilet paper machines.
Pulp Preparation:
The first step in producing toilet paper is the preparation of the pulp. Wood chips or recycled paper are processed in large machines called pulpers. The pulpers break down the raw material, removing impurities and creating a slurry-like mixture called pulp. This pulp will serve as the foundation for the toilet paper production process.
Paper Machine:
Once the pulp is ready, it is fed into a paper machine. The paper machine consists of a series of sections and components that work together to transform the pulp into thin sheets of paper. These sheets are then pressed, dried, and rolled onto large spools.
Rewinding and Slitting:
The large spools of paper are then transferred to rewinding machines. In this step, the paper is unwound from the spools and rewound onto smaller rolls, which are more convenient for consumer use. The rewinding machines also have slitting blades that cut the large sheets of paper into narrower strips, which will form individual toilet paper rolls.
Embossing and Perforation:
Toilet paper often features patterns or embossed designs on its surface. This is achieved through embossing rolls that press decorative patterns onto the paper during the rewinding process. Additionally, perforation blades create small dotted lines along the paper strip, allowing for easy tearing and separating of individual sheets.
Cutting and Packaging:
After embossing and perforation, the toilet paper strips are cut into individual rolls. These rolls are then packaged using automated packaging machines. The packaging machines wrap each roll in plastic or paper, ensuring hygiene and protection during transportation and storage.
Quality Control:
Throughout the manufacturing process, quality control measures are implemented to ensure that the toilet paper meets industry standards. These measures include monitoring the thickness, strength, and softness of the paper, as well as inspecting the embossing and perforation patterns. Any defective rolls are removed to maintain the overall quality of the final product.
Conclusion
The manufacturing process of toilet paper machine involves several intricate steps, from pulp preparation to cutting and packaging. Specialized machines and quality control measures ensure that the toilet paper meets the necessary standards of thickness, strength, softness, and hygiene. By understanding the manufacturing process behind toilet paper, we gain a deeper appreciation for the complexity involved in producing this essential everyday product.

Operation process of slitting machine
Today we will take everyone to understand the operation process of the slitting machine, so that we can have a good start when we operate the machine.
Start preparation 1. Check whether the power and air source are normal. 2. Check whether each transmission part needs to be filled with lubricating oil, and whether each part is loose. 3. Turn on the electrical isolation switch and check whether the voltage, current, and temperature are correct. 4. Turn on the power switch of the hydraulic system and check whether the oil level of the main hydraulic drive system and the pressure gauge display are correct and stable. 5. Open the start throttle valve and check whether the air pressure is correct (not less than 6.0bar) and stable.
Settings control 1. Set the slitting menu according to the PVC film type, thickness, length, width, etc. of the slitting plan. 2. Extract the corresponding PVC film file from the PDF. 3. Set the rewinding length and width of the film of corresponding specifications. 4. Select the corresponding winding station, adjust the pressure roller arm and pressure roller, and install the paper core of the corresponding specification. Loading, piercing and adding film 1. According to the requirements of the slitting plan, in accordance with the operating rules and actual conditions, hoist the corresponding parent roll on the aging rack, select the direction according to the corona surface inside and outside, and place it on the unwinding rack of the slitting machine, and press the control button Clamp and tighten the steel core, leave the steel core support arm and drive. 2. Film piercing​​: When there is no film on the slitting machine, the film must be pierced. Use the film-piercing device and function keys of the slitting machine to tie one end of the original film to the eyelet of the film-piercing chain, and press the film-piercing button to make the film evenly distributed on the rollers along the slitting process. 3. Film splicing: When there is film on the slitting machine and the roll joint is changed, use the vacuum splicing table, first start the film splicing table to the working position, manually flatten the film on the first traction roller of the slitting machine and start the upper vacuum pump for suction Film, so that the film is smoothly absorbed on the film splicing table, paste the double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding rack, start the vacuum to make the film absorb smoothly, and remove the tape. Put the paper layer, level the film, and the joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps, and open the splicing table to a non-working position.
start up Change the specifications and put the paper core on the inner and outer winding arms. When the press roller is in the ready state, the people around the machine should evacuate quickly. Slitting control 1. During the slitting operation, carefully monitor and observe the slitting effect, and appropriately adjust and control the slitting speed, unwinding tension, contact pressure, bending roller, edge material traction roller, edge guide, etc. Receipt 1. When the inner and outer ends of the winding are finished and the machine stops, use the film unloading button to place the film on the prepared film unloading trolley, cut the film, and paste the film roll with sealant. 2. Use the chuck release button to release the chuck and check whether the paper core of each roll of film rolls away from the paper core. If one end is still stuck on the paper core, remove the film roll manually. 3. Make sure that all the films leave the chuck and put them on the trolley. Use the film loading button to raise the winding arm, install the corresponding paper core, and place the film neatly on the paper core for the next slitting.
Stop device When the film roll reaches the set length, the equipment automatically stops.

Characteristics and uses of carbon fiber air expanding shaft
Today, Coreco introduces you to some information about air expanding shafts. The main points are the concept of air expanding shaft, the characteristics of air expanding shaft, the characteristics of carbon fiber air expanding shaft and its usage.
The concept of air expanding shaft
A air expanding shaft is a special kind of winding and unwinding shaft, that is, a shaft whose surface can be protruded after being inflated under high pressure, and the shaft whose surface part retracts quickly after being deflated is called air expanding shaft. It is called various names, such as air pressure shaft, expansion shaft, inflation shaft, air expansion roller, inflation shaft, pressure shaft, air expansion roller, etc.
Features of air expanding shaft
1 Inflatable operation time is short, the separation and placement of air expanding shaft and paper tube only takes 3 seconds to complete the inflating and deflating, and there is no need to divide any parts on the end side of the slack shaft that can be closely occluded with the paper tube.
2 Easy placement of paper tube: with the action of inflating and deflating, the paper tube can be moved and fixed in any position on the shaft surface.
3 Large load weight: The size of the shaft diameter can be determined according to the actual needs of the customer, and high hardness steel is used to make the load weight increase.
4 High economic efficiency: The shaft is designed for special function, and it can be applied to all kinds of paper tubes, such as thick, thin, wide and narrow.
5 Simple maintenance and long service life: The air expanding shaft is a single part, and each part of its structure has fixed specifications, which can be interchanged and used, making it easy to maintain.
First,Wide range of applications: As an independently designed part, the air expanding shaft can be used from 1 inch to 12 inches, with the length and size determined by the actual needs of the customer, and can be used for slitting, printing, rewinding, coating, laminating, bagging, papermaking, etc. or other related machinery.
Second, economic and efficient: the design of the shaft for the actual work needs of the design, the thickness and width of the various types of roll can be applied.
Third, the use of a long time, simple maintenance: Although the air expanding shaft is an accessory on the machinery, but its own structure of each part have fixed specifications, can be interchangeable, making it easy to maintain.
Fourth, a single accessory: air expanding shaft is a single spare part of the winding and unwinding machinery, each part of its structure has a fixed size, can be broken down and combined, so that maintenance is convenient, durable surface.
V. Professionalism: There are professional engineers and technicians for market research on the design and installation of air expanding shaft.
Sixth, large carrying capacity: air expanding shaft shaft can be designed according to the actual model, the use of high-quality steel, increase the carrying capacity. For example, the bearing weight of more than 1 ton can be selected from steel materials.
Seven, the operation time is short: separation and placement of the coil can be completed in just 2 seconds of inflating and deflating action, placing the coil is simple and convenient, safe and applicable. All machines and equipment used for winding and rewinding can be applied to the air expanding shaft. The longest air expanding shaft can reach six meters or more, and the shortest can reach several hundred millimeters, all according to customer needs to determine the length.
Eight, key-type air expanding shaft expansion up to a single key bar, the fulcrum point spread to each key bar, balance the force, can be applied to mechanical winding bearing heavy items.
Features and uses of carbon fiber air expanding shaft
Lightweight carbon fiber inflatable shafts are ergonomic, lightweight inflatable shafts with both durability and high-speed operation.
Carbon fiber inflatable shafts are 1/4 the weight of traditional inflatable shafts, making them ideal for high load carrying and manual handling and cutting. It can reduce occupational injuries of handling operators and also improve work efficiency. The optimized internal structure design is widely used in the air inflatable shaft industry, and it does not produce violent vibration even in the high speed field. Wide range of application, it can be applied to special surface treatment in various special environments (no pressure, corrosive, high temperature environment).
The use of carbon fiber air shaft is very wide, all machines with winding, unwinding and slitting can be applied to carbon fiber air shaft, even including light metal industry. For example: the air expanding shaft is mainly used in printing equipment: printing machine, flexographic printing machine, gravure machine, trademark printing machine, etc.; other machinery: coating machine, leather machine, shaping machine, embossing machine, slitting machine, die-cutting machine, rewinding machine, paper tube machine, bag making machine, laminating machine, laminating machine, film blowing machine, foaming machine, laminating machine, embossing machine, paper machine, non-woven machine, fabric inspection machine, hot stamping machine, battery equipment and other related machinery.

Analysis For Three Common Risk Control Points of Solventless Composite Technology
machine.html">solventless lamination machines. Significant advantages of the solventless composite process are reducing cost, high efficiency and energy saving, improving production safety, stability and product quality.
However, due to the immature solventless composite technology , and there are still some technical risks that are easily overlooked in the application for a flexible packaging company, leading to quality problems. Now we summarize three common risk control points of solvent-free composite technology.
1. The Technical Risk Of Increasing A Glue In Solventless Composite
Solvent-free composite adhesive with A glue and B glue, the adhesive mixing ratio is generally the weight ratio of A glue and B glue, rather than the volume ratio of both. The mixing ratio of the binder is usually determined by the adhesive manufacturer, as the proportion of the binder in different brands is generally different. The common ratios of A glue and B glue are 100: 80,100: 75,100: 50,100: 45. However, in the actual solvent-free composite production of flexible packaging companies, the ratio of the two-component adhesive will be disordered, which will affect the solventless quality of flexible packaging products.
Case
After printing, solvent-free compounding, the flexible structure of OPP / VMPET / PE has no quality problems.
The structural composite flexible bag is a low viscosity-free solvent-free binder brand and the proportion of A glue and B glue in actual composite production is 100: 67. When analyzing the cause of failure, we find that the bag is curled and the inner binder is not dry. Originally, because the composite film maturity is incomplete, prolongs the maturation time and then cuts into a bag. The problem of bag curling still exists and the opening performance has also deteriorated.
Combined with a ratio of A glue and B glue, it is not difficult to find that the bag is mainly caused by the excess of the A glue, because the solvent-free composite film is usually large and the effect of prolonging maturity is not obvious, water must be introduced into the cross-linking curing reaction with the -NCO.
The much more efficient methods are to rewind the composite film roll on a slitting machine and then increase the humidity of the workshop environment to absorb some moisture between the layer and the surface. The composite film, during aging, water will penetrate into the adhesive layer and reacted with an excess-NCO cross-linking curing reaction, so that the self-adhesive layer will be further completely cured, thereby effectively release the curling of the flexible packaging bags.
2. Risk Control For The Attenuation Of PE Membrane Peel Strength At Solventless Composite Material
A certain amount of linker is added to the film blow molding for reducing the friction between the film and the film, the film and the device, so that the surface of the film will be smoother, in order that the composite film operates successfully in the production process. Under normal circumstances, an excess sliding agent has added appropriately in the PE film, which can solve the phenomenon of abnormal increase in the friction coefficient of the solvent composite film after a certain extent, but this can also cause peel strength to be weakened, which is serious. When the aging is completed, the peel strength of the composite film is exceeded and in most cases, the peeling strength is reduced during the process of placing the composite film or during the cycle of the flexible packaging.
Case
The composite structure is a BOPA / PE film
Main parameters: a brand solvent-free adhesive, the amount of glue is 1.5 g / m2, aged at 40 ° C for 24 hours. The tracking and detection data of the peel strength of the composite film is as follows:
On October 13, the lateral peel strength was 15.37 N / m.
On November 4, the lateral peel strength was 4.62 N / m.
After the complex layer is peeled off, the surface of the PE film has a mist-like substance that can be wiped off.
On November 18, the lateral peel strength was 4.69 N / m.
It is closed to the final test data indicating that the peel strength of the composite film has reached a stable value.
Typically, the flexible packaging company only detects the peel strength of the composite film shortly after maturity. The composite film is rarely tracked during the process or the peel strength in the soft bag, which should be noted.
The migration of the solventless adhesive in the PE film produces a slipping agent, which is the main reason for the decrease in the peel strength of the composite film. We recommend a solvent-free adhesive. Add the formulated slipping agent to the formulation, so that the friction coefficient of the PE film in the solvent-free compound can be solved, and the problem of decrease in peel strength can also be solved.
3. Pay Attention To Identifying The Smell Characteristics Of The Solventless Adhesive
There are many factors that produce scent in the flexible packaging bag, such as residual solvent, ink resin, thin-film raw material resin, adhesive, etc. Although there is no solvent residue in a solventless composite, the resins and formulations in the solventless adhesive have a certain odor feature and some have effects after composite curing, even after the packaging. For flexible packaging companies, it is necessary to pay attention to the identification of the solventless composite film after the smell and prevent the problem.
a. In GB / T 10004-2008 standard, the detection method of packaging sensory indicators is specified, which is opening the box and lining the packaging film and immediately detect the smell.
b. Usually take a certain area of the composite films, cut into a 500 ml glass bottle, baked for 30 minutes at 60-80 ° C for detecting smell. It is also possible to seal the package in the air or actual content, rotating at a temperature of 50 to 60 ° C, tearing the package, and feel whether there is odor.
The odor of the composite film is mainly from a solvent-free adhesive. Therefore, the odor feature of the general solventless adhesive can be identified by the following method.
a. Take a certain amount of A glue and B glue with different brands for sensory testing and comparison.
b. Add a mixed solvent-free binder according to the specification to the glass bottle. Plastic film is placed in the bottom of the bottle and the cured adhesive is easily taken out and the crosslinking reaction is under 40-50 ° C. After an hour, the odor characteristics are determined. This method is more suitable for practical applications, including the odor characteristics of the resin itself.
Solvent-free composite technology is a production technology which is more and more widely used in the flexible packaging industry with the advantages of safety, environmental protection, saving costs. Through the learning of the common risk control points of solventless composite technology, the efficiency of solventless lamination will be improved.

What Is The All-in-one Web Guiding System
Once there is not an alignment of the coils, it will cause errors in the subsequent steps and the material wasting or the downtime of the machine. Therefore, when processing the web, the web guiding is necessary for the offset and it is widely used in a bonding machine, a printing machine, a coater, a paper machine, a dyeing machine, etc, which has various requirements for the winding and rewinding processes. An all-in-one web guiding system refers to the technical operation of the coils to keep the edge of the coil neat and consistent during spraying, printing, die-cutting, lamination, slitting, or other coil winding processes. Its wide applications have brought huge benefits to the coil industries. The all-in-one system has automated industries such as corrugated paper, textile, printing, labels, papermaking, plastic film, building materials, tires, and non-woven corrugated paper processing.
The Work Principle Of All-in-one Web Guiding System
The high-precision, high-speed, and high-efficiency coil automatic processing has high requirements for the lateral position of the controlled coil. Equipped with a high-performance automatic web guide system is the key to improving coil production capacity and output. The coil will shift laterally during moving, unwinding and rewinding. Therefore, the web guiding system can be installed in the above three positions for controlling the coil to pass through the designated position accurately.
All-in-one web guide machine adopts high-speed microprocessor, digital, modular and intelligent circuit design. The advanced programming, user-friendly interface, high-performance components and complete circuit protection design, make the system run continuously and stably. The response time of the control system is less than 0.01 seconds and the accuracy of the system itself can reach 0.01mm. During the coil winding process, the web guide sensor detects the position of the edge or line to pick up the deviation signal of the edge or line position.
Then the position deviation signal of the web guiding machine is sent to the web guide controller for logical operation. After the judges and processes of the control unit, it will control the drive motor to skew the web to the correct position.
The Functions & Advantages Of All-in-one Web Guiding System
The high-performance web guide system has a fast response time, high-speed CPU calculation and can support ultrasonic sensors, photoelectric sensors, CCD sensors for the different response of coils. It has the advantages of simple and practical operation, ball screw, high precision, low noise, maintenance-free, long service life, flexible installation.
Center compensation deviation web guiding can quickly guide the high-frequency feed errors. It integrates operation and control technology with a highly compact web guide. The guiding system has an innovative sensor detection real-time display and a real-time feedback system for system detection information.
The all-in-one system is driven by a brushless DC servo motor and precision ball screw, with compact structure, good mechanical rigidity, low inertia, high precision, suitable for high-speed and high-precision web guide in coil processing.
Three Detection Methods Provided By All-in-one Web Guiding System
The All-in-one web guiding system provides three different detection methods, which include edge detection, line tracking, or alignment detection. The drive system is driven by a brushless motor and the drive stroke is strictly proportional to the coil offset. The system can also be used in conjunction with different sensors to meet the needs of different coils, such as ultrasonic sensors, photoelectric sensors, CCD sensors, etc. The microcomputer digital controller provides precise control for the various functions of the guide system.
Daily Maintenance Of All-in-one Web Guiding System
1.Alignment: Tools, workpieces and accessories should be placed neatly. The web guiding system should be equipped with thorough protection equipment.
2. Cleaning: Cleaning inside and outside including all sliding surfaces, guidelines, gears, racks, etc, ensuring all parts will not leak oil, water, air, or electricity.
3. Lubricating: Refuel and change oil timely. The oil quality meets the requirements. Oil tanks, oil guns, oil cups, lumps, tubes should clean and keep complete.
4.Safety: The operation personnel should be familiar with the maintenance structure of the web guide system, complying with the operating procedures and reasonably use the all-in-one system with daily maintenance, carefully maintenance tools to prevent accidents.
