  • Patent number: 4767076
    Abstract: A mechanism for automatically feeding and collecting elongated cores of rolled fabric, which is used with an unrolling machine for unrolling fabric from the cores. The mechanism includes elongated frames on which endless link chains circulate with pairs of hooks for supporting ends of the cores. Parallel stock arms provide cores of rolled fabric to the hooks at a rear side of the frames. The cores of rolled fabric are removed from the hooks at a forwardly extending upper portion of the frames. Guide rods below the upper portion of the frame guide empty cores from the unrolling machine to the hooks as they circulate along the lower side of the frames. Spaced collector arms direct the empty cores dropped from the hooks at the bottom of the frames, away from the frames for removal from the mechanism.
