Abstract: A method of forming a tray includes obtaining a blank, the blank having a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels. The method further includes positioning the blank in a blank feeder assembly of a system for forming a tray, moving the blank to a tray forming assembly, the tray forming assembly including a tray forming assembly, the tray forming assembly including a turret assembly comprising a plurality of female tray forming members, the tray forming assembly further comprising a piston assembly including a male forming member, positioning the blank between the turret assembly and the piston assembly, and moving the piston assembly into at least partial engagement with the turret assembly to form a tray from the blank.

Abstract: A multi-functional cam system for controlling movement of a portion of a machine performing repetitive operations. A cam has a contour designed to control at least two different sequences of motion for a mechanism driven by the cam. The desired sequence of motion is obtained by registering the cam on its shaft to the position corresponding with that sequence of motion, then locking the position of the cam relative to the shaft. The mechanism that attaches the cam to the shaft includes a two-part hub, the two parts being axially clampable, a sleeve attached to the cam, the sleeve having a portion that is clamped between the hub parts, and a radially expandable locking device operating between the first hub part and the shaft. The clocking mechanism includes a sleeve tab extending axially from the sleeve, and at least two hub tabs extending radially from the first hub part.
