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 complimentary to an internal shape of at least a first portion of the container, and the second mandrel has an external shape complimentary 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.

A mandrel wheel for producing packages is illustrated and described, including: a mandrel wheel shaft having a central axis, a plurality of mandrels attached to the mandrel wheel shaft, an inflow for a coolant and an outflow for the coolant. The mandrels form at least one mandrel group, the mandrels of which are arranged in a plane perpendicular to the central axis of the mandrel wheel shaft. Each mandrel has a hollow space for the coolant, which is connected to an inlet and to an outlet separate from it. At least one distribution element is provided, which connects all inlets of a mandrel group to the inflow and which connects all outlets of the same mandrel group to the outflow, so that the mandrels can be cooled more effectively.
