Abstract
An apparatus for molding a plastic cap onto a pre-formed metallic shank includes a shank insertion device for inserting the shank onto a carrier member such that a head of the shank is elevated above the carrier member. A molding device, having an open mold cavity engages the carrier member such that the carrier member acts as a portion of the mold. A contour forming device can be used to form raised contours in said carrier member prior to the insertion of said shanks at said shank insertion device. A feeder mechanism is provided for drawing the carrier member through the contour forming device, the shank insertion device, and the molding device.
