APPARATUS FOR DEEP DRAWING AN OPEN BOWL

摘要

An apparatus for deep drawing a bowl from a blank of deep-drawable plastic material is provided comprising deep drawing tools, and cooperating jaws including an outside heating jaw and a forward feed heating jaw. The deep drawing tools and cooperating jaws are movable relative to each other to advance a blank of deep-drawable material for preheating, forming, and deep drawing a bowl open at one end therefrom. The outside heating jaw includes at least one outside suction plate to retain the blank, and intermittently moves in a first direction into and out of cooperating relationship with the forward feed heating jaw. The deep drawing tool also intermittently moves parallel to the first direction into and out of cooperating relationship with the forward feed heating jaw. The forward feed heating jaw includes a plurality of main suction plates secured to a heatable carrier to retain and heat the blank as it advances thereon. The forward feed heating jaw is intermittently moved in a second direction perpendicular to the first direction to alternately position different ones of the main suction plates into cooperating relationship with the outside suction plate of the outside heating jaw.
