Abstract
A tray-like mandrel for an automatic packaging machine has a telescoping bottom so that it may be made wide in order to receive a product or narrow in order to fit into a box. The telescoping is controlled by a slot track cam extending along a path followed by the mandrel. A cam follower riding in the slot track adjusts the tray width.
