Abstract
An extruder or the like, continuously issues a heated plastics material in the form of an elongated web, which is moved sequentially to molding and article severing stations. The products cut out are moved to lip rolling printing and drying stations. Articles such as containers are formed by the mechanism which includes a turntable assembly for varying the length of the web travel path between an extruder and forming station to thereby control the residual heat in the web at the time of forming, and a molding drum with improved plug assist devices which are air powered and also include air emitting ports to move the web into intimate engagement with the mold cavities as a final forming step under controlled conditions which assure that the pressure is applied at exactly the proper time. The system includes a lip curling system which feeds containers severed from the web in stepwise fashion through forming roll sections and releases them in timed relation to indexible mandrels. The system further includes a printing assembly which utilizes offset printing mechanism in combination with the mandrels, and associated ink drying mechanism, to print the containers prior to releasing or ejecting them.
