Description

Technical Field

[0002] Slitting machines are also called longitudinal cutting lines or longitudinal cutting machines. In the industrial field, they are mainly used to transfer and split wide strip raw materials into narrower widths and roll them into small bundles according to market needs. For example, the production of PP film, foam, optical film, tape and other materials requires the use of slitting machines for cutting and rolling. When slitting and rolling these materials, there are often different processing requirements. They need to be slit into different sizes and rolled up. The slitting components and rolling components need to be replaced, which is troublesome to operate.
