Swirl tumbler

Apparatus for trimming and ejecting articles integrally thermoformed in a sheet of thermoplastic material from the sheet including a pair of opposed trim dies which will trim parts out of a web of thermoplastic material. Apparatus is provided for pushing the trimmed parts out of the trimming station at a greatly accelerated rate. The apparatus includes a pusher member reciprocally movable in a to-and-fro path of travel between a retracted position and a forward ejecting position. Apparatus is provided for moving the ejector mechanism in the to-and-fro path and includes a toggle linkage mechanism which engages a cam for movement between relatively folded positions on one side of a plane and relatively oppositely folded positions on the opposite side of the plane to rapidly advance and even more rapidly retract the pusher member.
