A Method Of Manufacturing An Insertion-Type Seam For Mak- ing A Cloth Belt Endless, And Seaming Machine 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 in- tricate 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 productivi- ty 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 re- turned and re-woven about a central wire of any desired cross-sectional area, said central wire being disposed in the centre of the auxiliary warp strip and consisting of at least one wire, so that in accordance with the weaving progress 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 be- ing looped about the central wire, the warp ends after in- sertion into the shed made in accordance with the weaving order being beaten up in parallel to the selvedge.
