Abstract
A machine for forming a container from a blank of sheet material includes a frame, a mandrel assembly mounted to the frame, a pre-folding assembly, and a transfer assembly. The mandrel assembly includes a first mandrel and a second mandrel. The first mandrel has an external shape complementary to an internal shape of at least a first portion of the container. The second mandrel is positioned downstream from the first mandrel, and has an external shape complementary to an internal shape of at least a second portion of the container. The pre-folding assembly is configured to fold a first portion of the blank around the first mandrel to form a partially formed container. The first portion of the blank corresponds to the first portion of the container. The transfer assembly is for transferring the partially formed container from the first mandrel to the second mandrel.
