Abstract
1346925 Seaming non-metallic sheet material TELLEBORGS GUMMIFABKIKS AB 19 April 1971 [16 April 1970] 27115/71 Heading B5K [Also in Division B8] In a method of manufacturing from an elastomer, an endless conveyer belt of a thickness which is large in relation to the intended radius of curvature of the belt around the drive and end pulleys thereof, long lengths of conveyer belt material are manufactured and cut into short separate belt lengths the ends of which are spliced to form an endless conveyer belt having a carcass consisting of at least one longitudinally tension-reinforcing ply 15 and several transversely tension-reinforcing plies 17-19 and having a wear resistant cover 20 fixed to the transversely tension-reinforcing plies of the carcass. The invention is characterized in that in the manufacture of the carcass of the long conveyer belt lengths, the longitudinally tensionreinforcing ply or plies are made in continuous lengths while the transversely tension-reinforcing plies are made shorter lengths and are spaced apart along the longitudinally tension-reinforcing ply or plies, each space 10 between the lengths of the transversely tension-reinforcing plies corresponding to a splicing area 14 when the short belt lengths are spliced together in a series to form the manufactured endless belt. A further feature of the invention is that the longitudinally and transversely tension-reinforcing plies are vulcanized with spacer pieces 13 placed in the spaces and are removed after the vulcanization. Upon splicing the short belt lengths formed by cutting the long conveyer belt lengths and intended for the manufactured endless belt, a butt joint is formed between the ends of the longitudinally tension-reinforcing ply or plies. A piece of a tension-reinforcement ply 23 which with regard to strength, substantially corresponds to the longitudinal tension-reinforcement of the remaining part of the belt, is placed in each of the spaces between the ends of the transversely tension-reinforcing plies. While omitting at least one transversely tension-reinforcing ply, such a number of transversely tension-reinforcing ply pieces 24, 25, are inserted on top of each other in each of the spaces that the conveyer belt carcass has a substantially uniform thickness within all parts of the composite conveyer belt. In cutting the long conveyer belt length into short lengths, the longitudinally tension-reinforcing ply or plies are cut obliquely across the conveyer belt. Fig. 2 shows two ends of two belt lengths in alignment for splicing and it shows the alignment of the inserted reinforcement ply 23, the additional transversely reinforcing ply pieces 24, 25, and the portion of the wear resistant cover 20 which covers over the joint. In addition there are thin rubber interlayer portions 21, 22, and 26, inserted in, and covering the joint.
