Abstract
A method for making a collated fastener assembly includes the steps of arranging a plurality of fasteners each having a head and a tip, in a row parallel to one another, the fasteners being arranged in a plane. The plurality of fasteners are preheated to elevate the temperature of the fasteners and a molten polymer material is applied onto the preheated plurality of fasteners. The fasteners, maintained in the plane, are conveyed with the molten polymer thereon between a pair of forming wheels. The molten polymer material is molded onto the preheated fasteners and between adjacent fasteners to form a plastic molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. A cooling vapor is sprayed onto the fasteners and the plastic molding as the fasteners and the plastic molding exit from between the molding wheels. A gaseous cooling stream is forced over the fasteners and the plastic molding to cool the strip to form the fastener assembly.
