  • Positioning pile yarns in a gripper axminster carpet weaving machine
    Patent number: 5806568
    Abstract: For positioning pile yarns in variable selection positions in a carpet weaving machine of the gripper Axminster type, in which pile yarns (1-8) of different colors are placed next to each other in a line in pile yarn loaders (10), each pile yarn loader (10) is brought directly from a selection position to a following selection position. The selection movement thereby remains limited to moving over the distance between two successive selection positions.
