1,027,112. Jointing; making pipes, silencers, filters &c. WURTTEMBERGISCHE METALLWARENFABRIK. April 8, 1964 [April 10, 1963], No. 14525/64. Headings B3A and B3V. [Also in Divisions F1 and F2] A method of joining the edges of one or more parts made from metal filaments comprises compressing the edges to be joined to reduce the pore-volume, as by rolls or a press, and then connecting the edges as by welding, riveting, screws, pegs or an adhesive. The edges may be overlapped, and the joint-thickness may be less than that of the parts 3. Alternatively, the edges may be compressed and turned into flanges 2, Fig. 4 (not shown) or a single part 1 may be formed into a hollow cylinder, Fig. 6 (not shown), for use as a filter, silencer or a pipelagging. A metal reinforcing strip or strips may be welded or soldered between or externally of the edges to be joined. Filaments or powder of another metal may be dispersed on or in the joint surfaces. |
