Abstract: In the case of a hinge for the connecting of a temple shaft with a hinge piece of a spectacle frame, at least one hinge eye is located on only one of these elements (the hinge piece or the shaft of the temple). The hinge pin running through this eye is designed in one piece with the other element (the shaft of the temple or the hinge piece). For this purpose, either the hinge pin of plastic is injection molded into the opening of the hinge eye or the hinge eye of plastic is injection molded around the hinge pin. In this case, one preferably proceeds in such a manner that one of the two elements with the associated hinge eye or hinge pin is formed first and that this initially formed element forms a part of the surface of the cavity of the injection molding tool for the other element such that the other element is injection-molded directly onto the initially produced element.

Abstract: A process for fitting temple end pieces onto the ends of the temples of a spectacle frame with a simplified manner of trimming the ends of the temples to the proper length and affixation of the temple end pieces thereto in the proper angle of rotation about the axes of the temples is disclosed together with apparatus for performing the process.
