  • Devices for folding into the warp shed both ends of a weft thread in a fabric made by a shuttleless loom having a continuous weft supply mechanism
    Patent number: 3951177
    Abstract: Means are provided for entraining the free ends of weft threads extending from a formed fabric in movable suction hoses at each side of the loom. The hoses manipulate the weft thread ends into a position adjacent the sheds where hooked needles engage and fold the ends into the shed prior to beating. The weft threads on the side of the fabric which are attached to bobbins are folded into the sheds according to the pick repeat of the loom and the threads on the opposite side are folded into the next shed.
