ABSTRACT:
An apparatus and method for molding articles of manufacture of resinous materials whereby, the surface of the molded article contains a pile-like texture or structure. The pile-like structure is composed of material of the surface stratum of the article and is formed by the adherence of such material to the surface of the mold cavity wall in which the article is molded and by pulling the article away from the mold cavity wall while at least the surface stratum thereof is in a deformable condition such as a semimolten or plastic state resulting from the elevated temperature thereof caused either by the manner in which it is cooled or by applying heat thereto through the mold cavity wall.
