Description

Technical Field

[0002] At present, the gasket cutting machines on the market all use a plug-in vibrating knife bar. The vibrating knife bar and the machine head are two independent parts. When working, the vibrating knife bar is inserted into the sleeve of the machine head and then clamped. This vibrating knife bar is suitable for cutting some light, thin, and soft materials, and the precision requirements for the processed materials are not high, such as cloth, sponge, cardboard, etc. However, this is not the case in the gasket processing industry.
