Observe the step-by-step operation and see practical examples of usage. In this video, we demonstrate the testing process of a stainless steel warp knitting slitting machine designed for producing vegetable bags. You'll see how the machine slits HDPE film into precise strips, the role of opening rollers, adjustable flat knives, and transport rollers in the process, and how the integrated winding beam devices handle selvedge yarn. Watch the complete workflow from film feeding to final product formation.
