DLQF800 High-Speed Blunt Knife Cold Cutting Machine
The high-speed blunt-blade cold-cutting and sewing integrated machine is a new generation of integrated equipment designed for the large-scale production of woven bags. Its core technological highlight is "high-speed operation + blunt-blade cold cutting," integrating automatic feeding, precise hemming, smooth cutting, and robust sewing throughout the entire process. Unlike traditional hot or sharp-blade cutting methods, it uses a specially designed blunt blade combined with a cold-state cutting principle to achieve melt-free edge cutting of woven bags during high-speed operation. Simultaneously, through an integrated mechanical transmission system, it completes the fully automated operation from roll material input to finished product output.
