Process and device for positioning handles or rigidifying elements on a
tubular sleeve
摘要:
A method for positioning handles on a sachet-type container made from a flexible synthetic material comprises attaching handles to a sleeve of synthetic material while the sleeve is on the mandrel. The sleeves are cut and flap-like corner portions are folded over onto the handles. The handles may be fed from a magazine.
