Measures to ensure the quality of the protective film roll
Jun 20, 2019
To ensure the quality of the slit of the protective film roll, first of all, there must be a stable tension, which also affects tracking and correction. The protective film web must look very flat before entering the shearing knife. The pitch setting of the tool determines the slit width. The positioning of the tool does not stop, shift, shake, skew, and other conditions may cause the cut point to be incorrectly set.
Protective film rolls must have uniform width and spacing, and must have uniform thickness, coefficient, and splice points. The feed take-up reel cannot exceed the range or speed of the web corrector. However, the unevenness on any film web should be flattened under normal tension.
The sensor must constantly detect the edge of the slit, and any detection errors or blind spots will directly lead to the failure of the protective film roll. The corrector must be tightly controlled and reacted at all times, and the range and impact speed must match the quality and speed of the feed roll.
In the normal production of protective film roll cutting, do not think that the precise positioning of the film strip will help the knife to automatically correct the position. In production, many times from the calibration to the tracking of the slitting knife will be wrong, but as long as the short film web route is guaranteed, the ideal tension standard cylinder reel, qualified traction and high quality reel correction position will help reduce the film transfer process.
