Method for economizing material of gripper loom and apparatus thereof

Abstract

The invention relates to a method for saving materials for a gripper loom and a device thereof. A movable scissors device is arranged on the position on one side of the gripper loom, which is fixed with scissors previously; a warp edge thread feed wheel, a warp edge thread separating mechanism and a warp edge thread winding device are arranged on the other side of the gripper loom; on one side of the movable scissors device, when a woof feed mechanism of the gripper loom pushes forward, the movable scissors device withdraws to avoid impacting with the woof feed mechanism, while the woof feed mechanism returns, the movable scissors device returns back, and cut off a woof yearn; and on the other side of the movable scissors device, a warp edge thread used for nipping the woof yarn to move from the warp edge thread feed wheel towards the warp edge thread winding device, and passes through the warp edge thread separating mechanism in the middle, and under the action of the warp edge thread separating mechanism, the warp edge thread is separated from the woof yarn which is knitted in a knitting area. Through the method and the device, the invention has the advantage of effectively saving materials.

Description

technical field [0001] The invention relates to a method for saving materials in weaving, in particular to a method for saving materials for a rapier loom. [0002] The invention relates to an accessory used on a textile machine, in particular to a material-saving device for a rapier loom. Background technique [0003] Rapier looms are mature equipment with simple structure and strong adaptability in the textile industry, and are widely used in the textile industry at present. As shown in Figure 1, the working principle of the rapier loom (1) is to weave the weft thread (2) through the wire feeding device (51), the wiring device (5) and the warp thread (21), and the rapier loom ( 1) Both ends will produce waste of a certain size and length. The weft thread (2) is continuously propelled by the weft thread propelling mechanism (12) and is woven together with the warp thread (21). At the two ends (V) on the sidemost side of the rapier loom (1), the (W) area has no warp thread...

Problems solved by technology

As shown in Figure 1, the working principle of the rapier loom (1) is to weave the weft thread (2) through the wire feeding device (51), the wiring device (5) and the warp thread (21), and the rapier loom ( 1) both ends will produce waste of a certain size and length

The weft thread (2) is continuously propelled by the weft thread advancing mechanism (12) and is woven together with the warp thread (21). At the two ends (V) on the sidemost side of the rapier loom (1), the (W) area has no warp thread (21) , will produce useless weft waste (23), and since the position of the fixed scissors (11) is fixed, in order to avoid collision with the weft advancing mechanism (12), the distance away from the effective weaving area will be relatively far, forming a large The weft line waste edge (23) of area causes great waste; The warp line (22) shown in the figure is to prevent the weft line (2) from retracting because of its own elasticity, and plays a role in clamping the weft line (2). To avoid the shrinkage of the weft thread (2) and produce inferior fabrics, but at present, this kind of warp thread (22) often cannot be reused, resulting in great waste
