A slitter rewinder is an indispensable part of the packaging converting industry. It converts large rolls of materials into narrower rolls with different slit widths. A slitter rewinder machine can not only slit but also rewind the materials for further processing steps. Slitter rewinders have a wide range of applications, including paper, film, foil, plastic, and other flexible packaging materials in the converting industry.
There are three slitting methods: shear slitting, score/crush slitting, and razor slitting. These slitting methods are determined by several factors such as material types. As for shear slitting, two rotary knives (a dished top knife and a bottom knife) work like scissors that are ideal for slitting paper, film, foil, etc.
Dished knives and bottom knives play a vital role in the slitting process. With outperformed slitting knives, the efficiency and product quality can be greatly improved.
