摘要：A machine for the manufacture and stacking of bags, pouches and the like made from a thermoplastic material in which the upper welding jaw and a belt driven angled cutting blade are mounted in fixed manner to the machine. The lower welding jaw is mounted for moving vertically and has a downstream projecting holding shoulder which has a transverse groove with stepped edges forming a blade support in the raised position of the lower jaw. A blocking shoe is provided a short downstream distance from the holding shoulder and has a blade spring member attached to a bottom surface which extends in an upstream direction toward the lower welding jaw. The blade spring operates to first tension the thermoplastic segment in the raised position of the lower jaw prior to the cutting by the transverse moving blade and then to deliver and hold the severed end of the formed bag on a resilient pad on the stacking table.
