Problems solved by technology

However, for some special weft yarns with flat shapes, the weft yarns cannot be twisted and not wear-resistant during the weaving process, the existing weft insertion devices of looms cannot meet the requirements at all.

Embodiment Construction

[0022] like figure 1 , 2 As shown, the radial unwinding weft carrier of the present invention includes a shuttle box 1 and a weft storage device located in the shuttle box 1, and a yarn outlet 7 is provided on the side of the shuttle box 1 for installing and dismounting the weft storage device And extract weft yarn, storage weft device comprises yarn storage shaft 2 and the mandrel 3 that is positioned at storage yarn shaft 2, mandrel 3 is fixed in the shuttle box 1 by clamping device, and storage yarn shaft 2 can rotate on mandrel 3.

[0023] The lower surface of shuttle box 1 inside is provided with through hole 8, is used to place mandrel 3, and the upper surface of shuttle box 1 is provided with through hole 9, and mandrel 3 one end is provided with flange 31, and the other end is inserted into through hole 9, clips The tightening device is located on the flange 31. Both ends of the mandrel 3 are covered with damping washers 14 for preventing the yarn storage shaft 2 fro...

Abstract

The invention provides a radially unwinding filling carrier which avoids the twist phenomenon and a radially unwinding method thereof. The radially unwinding filling carrier comprises a shuttle box and a filling storing device, wherein the filling storing device is positioned inside the shuttle box; a yarn outlet is formed on one side of the shuttle box; the filling storing device comprises a yarn storing shaft and a central spindle positioned inside the yarn storing shaft; the central spindle is fixed inside the shuttle box by a clamping device; and the yarn storing shaft can rotate on the central spindle. In the radially unwinding filling carrier and radially unwinding method thereof, the original axial unwinding is changed; a radially unwinding yarn is adopted to remove the twist of the yarn generated in the unwinding process; the manufacturing requirement of a flat yarn can be met; and the abrasion of the yarn is greatly reduced.

Description

technical field [0001] The invention relates to a weft carrier of a loom and an unwinding method thereof, in particular to a radial unwinding weft carrier and a radial unwinding method thereof. Background technique [0002] During the weft insertion of various looms at present, the weft yarn is all unwound from the weft feeder or shuttle in the mode of axially pulling out. Every time unwinding a circle, the weft yarn will be twisted once, and a twist change will occur. Yet for the weft yarn of some flat shape, in the weaving process, weft yarn can not be twisted and the special fabric variety that requires such as not wear-resisting, existing loom weft insertion device can not satisfy its requirement at all. Because the shuttle (weft carrier) and the weft feeder in the weft insertion device of the existing loom are all axial unwinding, every unwinding one circle is twisted once. Contents of the invention [0003] The invention provides a radial unwinding weft carrier with...
