ABSTRACT:
A device for closing a lid of a cap while the cap is still in the mold where it was formed. The device includes a plate forming the moveable side of a parallelogram that rocks between the mold plates during mold opening to press the lid closed and then rocks back out of the way to allow part ejection. The motion is activated by mold opening so the molding cycle is not lengthened by its action.
