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.

A method of forming a tray includes obtaining a blank, positioning the blank in a blank feeder assembly of a system for forming a tray, moving the blank from the blank feeder assembly to a nipping assembly, and moving the blank to a tray forming assembly, the tray forming assembly including a tray forming apparatus. The method further includes positioning the blank between a first tray forming portion of the tray forming apparatus and a second tray forming portion of the tray forming apparatus, the first tray forming portion includes a forming block that defines an interior, and the second tray forming portion includes a tray forming member, and driving the forming block into engagement with the blank and the tray forming member such that the blank and the tray forming member are at least partially received in the interior of the forming block to form a tray.
