ABSTRACT:
A mold-closing and holding mechanism, especially for a deep drawing apparatus making hollow articles from a thermoplastic web provides force-storing elements between the mold halves and the drive so that when the drive which can use a check motor is cut off, the force-storing elements can continue to exert a uniform closure force at least upon the regions at which a weld is to be formed from the shaped parts.
