Plant for the continuous verfertigung of bags made of polypropylene, polyethylene, pvc or similar plastic materials.

摘要

Plastic bags are fashioned by sealing two layers of polypropylene, polythene or PVC film along two, three or four sides, often with holes punched along one of the longitudinal edges, the continuous film being uncoiled from a bulk supply turned out by chill-roll extrusion methods. The plant disclosed comprises a folding station (5), then in sequence, a heat-seal station (11), a cooling stage and a cutting station (40), and turns out the bags in an entirely continuous process.
