ABSTRACT:
The invention is directed to a method of manufacturing an insertion-type seam for making a cloth belt, especially a wire cloth, endless, in which the warp ends of each cloth side are interwoven with an auxiliary warp strip, and to a seaming machine for carrying out the method. In order to mechanize and automate the conventionally required intricate and time-consuming manual work for preparing the insertion-type seam and to thereby achieve a significant relief of personnel and thus an improvement in productivity and the quality of insertion-type seams, it is proposed that the warp ends after unravelling of the right-hand and the left-hand cloth sides are strung in a magazining bunch, and thereafter mechanically individually separated in accordance with the weaving order and alternatingly returned and re-woven about a central wire of any desired cross-sectional area, said central wire being disposed in the center of the auxiliary warp strip and consisting of at least one wire, so that in accordance with the weaving process a warp end of the right-hand and the left-hand cloth side alternately winds about the central wire, while the respective opposite warp is re-woven without being looped about the central wire, the warp ends after insertion into the shed made in accordance with the weaving order being beaten up in parallel to the selvedge.
