Apparatus and method for producing tubular sections for manufacturing bags

摘要

A device for generating hose sections, which include paper, to produce bags, has an unwinding device with which a web can be unwound from a roll, a perforation device with which perforations can be inserted into the web extending perpendicular relative to the travel direction of the web, a hose forming device which is arranged. downstream in the production process relative to the perforation device and with which the edges of the web can be made to overlap to form a hose, and a separating device for hose sections. The perforation device includes a laser beam device with which a laser beam can be guided to the web in order to insert the perforations.

主权项

1. A device for generating hose sections for the production of bags said device comprising:
an unwinding device with which a web is unwound from a roll; a perforation device with which perforations are inserted into the web, said perforations extending perpendicularly over the web relative to a travel direction (z) of the web, said perforation device including a web deflecting device having a first roller and a second roller configured to convey the web in a plane, and a laser beam device with which a laser beam is guided to insert the perforations in the web, with said web deflecting device being displaceable in a direction that is substantially perpendicular to the plane of the web; a hose generation device arranged downstream relative to the perforation device, said hose generation device placing edges of the web in an overlapping configuration so as to form a hose; and a separating device with which individual hose sections are separated from the hose along the perforations.
