Abstract
A fabricating apparatus for cuplike containers, including a continuously moving conveyor defining a closed path and having a plurality of spaced mandrels with an external configuration corresponding to the internal configuration of the containers. Processing assemblies located adjacent to a main conveyor act in timed relationship with the main conveyor to (a) preheat the mandrels, (b) form cylindrical sleeve blanks from a continuous web of thermoplastic material and telescope the sleeve blanks onto the mandrels, (c) simultaneously cut bottom disc closures from two continuous webs of thermoplastic material and deliver the discs serially to the mandrels, (d) rotate the mandrels carrying the sleeve blanks and discs as they are subjected to heat to shrink each sleeve blank about a mandrel in overlapped relationship with a bottom disc, (e) fuse the disc to the overlapping portion sidewalls of the container and (f) form a curved rim at the top of the cup to complete formation.
