Abstract:
1. Method for coating surfaces for fixing elements with hot-melt adhesive powder, whereby the pre-mixed adhesive in pulverized form is applied to the surfaces and is exposed to a thermal effect sufficient to adhere the adhesive to the surfaces by exerting a pressing force upon the adhesive, characterized in that the adhesive powder is filled into recesses in a working plate having contours that correspond to the surfaces of the element, and is then smoothed out in the desired thickness, the element, after being heated to the temperature required for adhesion of the adhesive powder to the surfaces, is positioned over the recesses that have been filled with the powdered adhesive, the adhesive powder is then pressed against the surfaces from below by tappets having a cross section that is matched to the recesses and top sides that are matched to the geometry of the surfaces.
