ABSTRACT:
A method and apparatus is provided for weaving which utilizes a plurality of moving warp sheds, wherein the sheds move in a direction parallel to the warp threads, and wherein gripper shuttles are employed for carrying weft threads from one side of the machine and through the moving sheds to the other side of the machine, with the gripper shuttles being unconnected to the machine, during their traverse through the moving warp sheds. The weft threads are supplied from a weft supply station which includes a plurality of stationary weft supply spools. The weft threads are supplied to a plurality of weft feeders and guides which operate to successively transfer the weft threads to the gripper shuttles. Once the gripper shuttles have been loaded with weft thread, the gripper shuttles are ready to be fired through the moving warp sheds. Before a gripper shuttle enters a moving warp shed, its lateral speed is synchronized with the lateral speed of the moving warp shed. Once the gripper shuttle enters the moving warp shed, it operates to lay weft thread in the moving warp shed during the entire time that it traverses the moving warp shed. As the gripper shuttle emerges from the moving warp shed, the gripper shuttle is received and stopped at a receiving station.
