  • Patent number: 4290458
    Abstract: Amultiple longitudinal traversing shed weaving apparatus comprises a weaving rotor having beating elements for the laid or inserted weft threads and shed-retaining elements which retain the warp threads, throughout a predetermined path, in their upper shed position and lower shed position. Each intermediate space between neighboring beating or beat-up elements has operatively associated therewith a respective shed-retaining element which determines the upper shed position or lower shed position and, viewed in the direction of travel of the warp threads, there is arranged forwardly of the weaving rotor a control means for the lateral deflection and selective allocation of the warp threads to a shed-retaining element which determines the upper shed position or lower shed position.
