Abstract:
A machine for forming a container from a blank assembly including a tray blank and lid blank includes a frame, a mandrel assembly mounted to the frame, a pre-folding assembly, and a glue panel presser assembly. The mandrel assembly includes a first mandrel and a second mandrel positioned downstream from the first mandrel. The first mandrel has an external shape complementary to an internal shape of at least a first portion of the container, and the second mandrel 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 assembly around the first mandrel to form a partially formed container. The glue panel presser assembly includes a first presser plate configured to form a first manufacturer joint, and a second presser plate configured to form a second manufacturer joint.
