Laminating machine manufacturers use a flat knife to cut like a razor, and the laminating machine manufacturers drop to fall in the process of material operation, so as to achieve the purpose of slitting. There are two types of this. Overhanging slitting is when the material passes through two rollers, the razor falls down to cut the material longitudinally. This slitting method is convenient for knife and easy to operate. Groove slitting is when the material runs on the grooving roller, the cutter is dropped into the groove of the grooving roller, and the material is cut longitudinally. When slitting cast PP film or film with narrow edge material, this slitting method is commonly used to improve the slitting efficiency.
1. The product to be constructed must be straight. Handle uneven paper with "lotus edge" and "tight edge" phenomena. Paper with "lotus edge" can be baked, and paper with "tight edge" can be hung.
2. Be sure to wait for the blot to dry before coating, otherwise it will cause blistering or hair pulling.
3. Spray as little powder as possible during printing, otherwise it will cause emptying and blistering at the powder pile. Before spraying the film, the powder should be disposed of. If the number of prints is large, it can be hung to remove the powder, and if the number of prints is small, it can be wiped manually.
4. When laminating, attention should also be paid to the direction of the paper strands, especially thick paper, to reduce the phenomenon that the paper is curled due to rolling and stretching.
