  • Shuttle return conveyor mechanism
    Patent number: 4330018
    Abstract: The conveyor belt for the shuttle return conveyor mechanism is formed with a support on the upper surface for laterally supporting a series of shuttles thereon and drivers which act as abutments for moving the shuttles from the catching mechanism to the picking mechanism of the weaving machine. The shuttles are thus conveyed directly on the conveyor belt and do not require separate guides or channels in the weaving machines.
