THERMAL PROCESSING OVEN IN A BLOW-FORMING FACILITY FOR THERMOPLASTIC RECEPTACLES

摘要

The invention relates to an oven in a production facility for thermoplastic receptacles, comprising a conveyor chain which is provided with gripping devices (16), whereby each gripping device engages axially with the neck of a receptacle blank in order to transport it into the oven. The invention is characterized in that the gripping devices are displaced axially by means of a mechanism which is provided with an arm (44) which can move along a path that is substantially parallel to the axial direction (An) in which gripping takes place and which bears an interface element (40) which is designed to come into contact with the gripping device (30). The invention is further characterized in that the interface element (40) is moveably mounted on the arm (44) to enable slip-free contact with the gripping device while it is immobilized in relation to the arm according to the axial direction in which gripping occurs.
