  • Device to distribute sliver automatically to spinning machines
    Patent number: 4922707
    Abstract: A device which automatically distributes new sliver to spinning machines. The device includes movable units which run in a track along parallel banks of spinning machines stopping at the machines which need to be refilled. Generally, these units transport full cans of sliver from a storage facility to the specific empty spinning machine where the units feed the silver into the spinning machine by placing the end of the sliver into a feed conduit. The units then transport the empty can to a facility where it can be refilled.
