Abstract: A collapsing core mould is provided for forming a moulded part. The collapsing core mould has a longitudinally moveable center section for withdrawing from a plurality of surrounding laterally moveable peripheral sections, at least some of which laterally moveable peripheral sections are also longitudinally moveable. Withdrawal of the center section allows lateral movement of the at least some of the peripheral sections toward each other. Subsequent longitudinal withdrawal of the at least some of the peripheral sections allows for the remaining peripheral sections to move toward each other and release the moulded part.

Abstract: The present invention provides a laterally movable lifting arm and follower which may be mounted adjacent a mold. The lifting arm is movable from a cap engaging position wherein it initially moves the cap away from the mold into the path of the follower. The cap is initially moved across the lid by lateral movement of the lifting arm. The follower is subsequently passed across the cap to lockingly engage the closure.
