Abstract
A method for making a collated fastener assembly includes arranging a plurality of fasteners in a row parallel to one another, in a plane, and spaced from one another, preheating the fasteners, applying a molten polymer material onto the fasteners and conveying the fasteners with the polymer into a mold cavity. The fasteners are maintained in the plane. The polymer is molded onto the fasteners and between adjacent fasteners to form a molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. The molding maintains the space between the fasteners. A cooling stream is introduced onto the fasteners and the molding as the fasteners and the molding exit from the mold cavity.
