ABSTRACT:
A container manufacturing apparatus comprises an endless conveyor continuously movable along a defined path and which has mounted thereon a plurality of mandrels in spaced apart relation. A sidewall blank feeder sequentially feeds blanks to the mandrels before each respective mandrel moves into a wrapping station wherein the sidewall blank is wrapped about the respective mandrel. The mandrel having a wrapped sidewall then moves to a station for receiving a formed bottom closure member after which the bottom closure member and the sidewall carried by the respective mandrel are moved to a station for heating a portion of the bottom closure member and the sidewall blank. After passing through the heating station the mandrel carrying the sidewall blank and bottom closure member moves through a bottom crimping station wherein a portion of the bottom closure member is bonded to a portion of the sidewall blank to form a container. After passing through the crimping station, the mandrel carrying the container moves to a finishing station which is operable for finishing the open end of the container and then removing the container from the mandrel. A conveying means is also provided for carrying the finished container away from the finishing station. The stripped mandrel then returns to pick up a new sidewall blank.
