Frequently asked questions in the application of tape slitting machines

1) Noise problem. Due to the strong adhesiveness of the tape master roll, the material will produce a loud tearing sound during the unwinding process. Workers who work for a long time and are affected by the noise will affect their hearing health. It is usually solved by wearing earplugs. Some slitting machines are equipped with a silencer cover at the unwinding end to effectively isolate most of the noise.
2) Knife sticking problem. In the front coating process, the adhesive layer coated by the material will produce adhesion to the circular blade, which will cause great wear during high-speed slitting and may affect the neatness of the slitting end face. Usually, a nozzle is installed above the cutter to spray anti-sticking liquid to ensure smooth cutting. An appropriate amount of anti-rust oil can also be added to protect the blade from corrosion. In addition, timely tool replacement and sharpening are also key to ensuring cutting quality.
3) Poor tension control. Stable tension is the top priority during the tape slitting process. If the tension is too small, uneven end faces or bubbles will appear. If the tension is too high, the internal stress of the film roll will be excessive, causing deformation or even breakage.
Changes in the diameter of the rewinding and unwinding will cause tension fluctuations. Generally, the unwinding part adopts constant tension control, and the rewinding part adopts taper tension control as the roll diameter increases. Usually the tape slitting machine manufacturer will establish an algorithm model for users to adjust parameters. . Users need to comprehensively combine different material properties and find the most appropriate cutting parameters in practice.
