Production of wound film strips on bobbins, comprises cutting extruded film into strips, with sub-group to be split into fibrils, before all being drawn together for bobbin winding

摘要

#CMT# #/CMT# Production of film ribbons comprises cutting an extruded film (3) into strips (7) with a cutter (6). The cut strips are drawn (12), and wound on to bobbins (23). Some of the cut film strips are separated into a sub-group (11), before bobbin winding (22), to be processed additionally by fibrillation (9) through a needle roller, and the fibrils are returned to the remaining cut strips, to be drawn together. #CMT#USE : #/CMT# For the production of wound bobbins of film ribbons which can be used for e.g. weaving big bag sacks and containers, floor coverings, and twisting into cords to stitch packaging materials. #CMT#ADVANTAGE : #/CMT# Film ribbons of different configurations can be produced from an extruded film. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of the film ribbon production line. 3 : extruded film 6 : film cutter 7 : cut film strips 9 : fibrillation station 11 : film strip sub-group 12 : drawing station 22 : bobbin winding station 23 : bobbin winders.
