Abstract
Abstract This invention relates to a fastening device which has a plate, a layer of hot melted adhesive adhered to one side of the plate and a mechanical fastening means protruding from the other side of the plate, and to an apparatus for applying the fastening device. The apparatus has an electrically heated element having an aperture therein shaped so that the mechanical fastening means can be passed through the heating element, control means for turning the heating element on and off, and gripping means adapted to clamp onto a portion of the mechanical fastening means which has been inserted through the heating element. The gripping means, which can be selectively moved between non-clamping and clamping positions, is adapted to hold the fastening device so that the side of the plate not covered with adhesive is in direct face-to-face thermal contact with the heating element.
