Melt blown fabric slitting machine is a kind of equipment for trimming and slitting wide materials according to different needs in the production process. Among them, the non-woven slitting machine is mainly used to slit wide webs into various narrow webs suitable for production needs. The slitting process includes two processes: unwinding and winding. The tension control of unwinding material and winding material is the key link of slitting machine. This machine is based on the original electronic control system with an automatic side-aligner control, which achieves the ideal effect, improves the working performance of the machine, and makes the machine more stable in high-speed operation. The winding is flat, the operation is simple, convenient and safe. Reliable and durable.
