Background Art

Warping machines can be divided into two categories, one is the traditional drum-type friction drive warping machine, the other is the new warping machine with direct drive of the warping beam. The pressure method of drum-type friction drive warping relies on the weight of the heavy hammer, the warp beam arm and the weight of the warp beam itself. The old machine was modified to adopt the horizontal pressure method. After the yarn of the slitting warping machine is led out from the bobbin on the creel, it is wound onto the drum one by one through the guide rod, rear reed, guide rod, photoelectric end breakage automatic stop plate, twisting reed, fixed width reed, length measuring roller and guide roller. When the shaft is reversed, all the warp yarns on the drum are withdrawn in the counterclockwise direction according to the double-dotted line as the weaving shaft rotates, and then rolled onto the weaving shaft.
