ABSTRACT:
An apparatus for fabricating a container made of foam sheet material. The apparatus includes a mandrel carrying drum that revolves about its longitudinal axis of symmetry. The drum contains a plurality of individual mandrels in radial alignment. Each mandrel revolves about its longitudinal axis as it forms a cylindrically shaped container blank. The drum carries the mandrels in an arcuate path, thus permitting work to be performed on the container blank as it passes a series of work stations.
A method of forming a container from foam sheet material is set forth wherein a severed sheet material is attached to a mandrel. The mandrel rotates about its axis to form a cylindrically shaped blank as the mandrel itself is being moved in an arcuate path. While positioned on the mandrel, the container blank is worked upon at a plurality of work stations, thus producing a final container with an end closure which may be apertured.
