Perforation Unit
  • The perforation unit adopts Burckhardt microneedle perforating rollers which create 64 pins per square centimeter, ensuring valve bags’ air permeability and tension;
  • The perforating rollers are made up of modular units, and if somewhere is damaged on the rollers, what can be replaced is the damaged unit rather than all the rollers, minimizing production cost;
  • The pin size adjustment device adopts a structure of threaded rod and handwheel. The handwheel has number marks, making the size adjustment convenient.
