Abstract
Continuous molding of objects using a rotatable molding wheel with peripheral orifices in accordance with the objects to be molded. Plastic is extruded upon the periphery of the wheel and a knife in substantially eliptical contact is used to skive film from the objects being molded. Following molding, selected portions of the objects can be selectively distended. Suitable distention can be achieved using diverging sprocket wheels. When the continuously molded objects are fasteners with filament-like portions, the diverging sprocket wheels can be used to stretch the filamentary portions and reorient their molecules.
