Abstract
A apparatus and method for making multiple layer molded padded products comprising at least three layers, the intermediate layer comprising padding. All of the layers are formed on male molds which are cast from a single master mold, thereby reducing mold costs and assuring perfect matching of the layers. The entire area of the female mold on which the intermediate layer of padding is formed is either completely cut away or is spaced away from the male mold so that the thickness of the pad is not substantially reduced during the molding operation. The female mold is heated and acts as an oven to draw back compressed fiberfill padding and/or to cure polyurethane foam padding.
Claims3
The method of forming a breast pad having a substantially thick layer of padding disposed adjacent to a relatively thin layer of fabric, said method comprising molding said layers simultaneously on a three dimensional male mold and a female mold, the entire inner area of said female mold being spaced away from the adjacent inner area of said male mold a distance at least equal to the thickness of the molded layer of padding, so that the portions of said padding forming the inner area of said pad are not compressed during said molding by engagement with said female mold, said female mold having a peripheral portion which engages the peripheral portion of said male mold around the entire periphery of said molds, thereby compressing and deforming said layers between the engaging peripheral portions of said molds simultaneously with the molding of the inner portions of said layers to form a precise cutting edge defined by the peripheral portions of said molds, said cutting edge extending around the entire periphery of each layer of said pad, said male mold being unheated and said female mold being heated and facing upwardly to form a heated enclosure which surrounds said male mold during the molding of said layers, said layer of fabric being heated to a temperature between 300.degree. F. and 400.degree. F., said padding being heated to a temperature between 100.degree. F. and 200.degree. F., and said female mold being heated to a temperature between 150.degree. F. and 200.degree. F.
