Abstract

A process and a device for producing hollow bodies of plastic by stretch-blow molding heated parisons, in which the parisons are inspected before being heated and at least some of the defective parisons are heated and are not separated out until after being heated. This method and the respective device can be implemented at low cost and with low space requirements and it has only a minor negative effect on output of finished hollow bodies.
