Method for manufacturing packages in the form of flexible tubes

摘要

An apparatus for manufacturing packages in the form of flexible tubes from a flexible, planar web (1) of packaging material has a forming shoulder (11) and a drawing-off device (13). In order to reduce friction between the web of packaging material and the forming shoulder, the latter has a vibrating part (21) in the region of its neck. The said vibrating part is preferably connected to an ultrasonic generator (20). <IMAGE>
