Abstract

See full text

A method of continuously producing an elongated strip-like fastener member is disclosed which facilitates highly efficient formation of the fastener member with a great multiplicity of resiliently flexible hook-like projections. The method comprises the formation of an extrusion of plastic material which is shaped between a pair of coacting first and second rollers. Notably, one of the rollers defines a plurality of hook-forming cavities about its periphery within which the hook projections of the fastener member are formed. The forming roller is suitably cooled so as to effect substantial reduction in the temperature of the molten plastic extrusion from which the fastener member is formed. In this manner, the fastener member may be removed or stripped from the forming roller without opening of the hook-forming cavities, thus promoting highly efficient formation of the fastener member without resort to unduly complex equipment of processes.
