ABSTRACT:
The packaging machine has a molding station comprising a reciprocating molding die for shaping thermoplastic sheet material to form packaging containers. Reciprocating drive is transmitted to the molding die by first engagement means provided laterally thereon and cooperating second engagement means provided laterally of the moving path of the molding die and opposite the first engagement means. The molding die may be moved into a retracted position at one end of its moving path, and when in this retracted position, the first and second engagement means are disengaged so that the molding die and any members secured thereto may be readily removed for replacement thereof and/or of molding inserts provided in a lower part of the molding station. In a preferred embodiment, the first and second engagement means are formed by a driving chain and engagement members, respectively, the engagement members being shaped to engage the chain links.
