Patent DE-3321348-A1 (DE)
Title: Universal joint element
Inventor: KRUDE WERNER DIPL ING
IPC: F16D3/40
Filed: 1983-06-13
Abstract: The universal joint element consisting of fibre-reinforced plastic has at one end of a tubular piece two diametrically opposite longitudinal webs which are connected at their ends by a transverse web and contained in which there is a bore for receiving each of the bearing bushes, the said bores in alignment with one another. The reinforcing fibres or fibre groups are at least partially guided by the longitudinal webs and the transverse web. While of low weight, the universal joint element allows stable trunnion-cross mounting, because the longitudinal webs do not undergo inadmissible torsional or flexural deformations even when transferring considerable torques. Joints having these joint elements have a great angular mobility, especially as the form of the joint element is also suitable for the winding technique. <IMAGE>

Abstract: The subject matter of the application starts from a method of attaching a soft-formed edge profile and a cover strip of veneer wood or plastic on top of it to the diagonally opposite edges of square or rectangular plate-shaped workpieces of wood or wood-like material, such as furniture front panels, by means of a machine continuously working the workpieces, in which method first of all the edge profile is cut at the respective workpiece edge, then the cover strip is moved up from an endless supply while conforming to the edge profile, is at the same time adhesively bonded onto the workpiece and is cut to length at the workpiece corners. In the process, the cover strips are to be joined at the workpiece corners exactly along the mitre edge which is formed by the edge profiles converging at the workpiece corners. To this end, first one pair of the parallel workpiece edges are cut, then the workpiece edges running transversely thereto are cut and the cover strip is moved up to their edge profile with a projecting length beyond the mitre edges formed by the edge profiles converging at the workpiece corners and is also cut off along the mitre edges, and then the cover strip is moved up to the edge profile of the workpiece edges cut first and is also likewise cut off along the mitre edges at the workpiece corners.
