ABSTRACT:
A cavity stripper which is positioned between two mold plates of a mold is used to remove a molded U-shaped article from a cup in one of the mold plates. The cavity stripper is movably attached to the mold plate that houses the cup. The cavity stripper is spring loaded such that it follows the moving mold plate for a short distance and by mechanical interference urges the molded article to remain with the mandrel during opening operations.
