In order to meet the requirement of smooth edge, it is necessary to install mechanical fold-in mechanism on the shuttleless loom. These mechanical fold-in mechanisms are complex in structure, large in size, troublesome to install, and high in manufacturing cost, which also increases the purchase of loom users. The cost
In addition, the above-mentioned mechanical tuck-in mechanism cannot meet the weaving requirements of high-speed rapier machines and air-jet looms, and also has defects such as inconvenient adjustment.
At present, there is no corresponding method for the smooth edge treatment of the cloth of the shuttleless loom

Embodiment
[0028] A method for weaving smooth-edged cloth on a shuttleless loom, the specific steps are as follows:
[0029] (1) Push the weft thread of the cloth into the U-shaped nozzle 13 by using the weft thread advancing mechanism;
[0030] (2) The solenoid valve drives the upper scissors 11 matched with the U-shaped mouth to move downward, and cuts the weft under the cooperation of the upper scissors 11 and the matched lower scissors 12; at the same time, the movable closed circuit block 14 matched with the U-shaped mouth 13 The same scissors 11 move downward together to close the U-shaped nozzle 13, so as to isolate and retain the cut weft thread in the U-shaped nozzle 13 that has formed a closed circuit;
[0031] (3) After the weft thread propulsion mechanism is restored, the solenoid valve controls the air jet to blow air towards the weaving area, and blows the cut weft thread waste into the weaving area, thereby weaving into a smooth edge;
[0032] (4) The upper scissors 11 an...

The invention relates to the technical field of looms, in particular to a weaving method for shuttleless loom plain-edge cloth.The method includes the specific steps of firstly, pushing weft of the cloth into a U-shaped nozzle through a weft push mechanism; secondly, making an electromagnetic valve to drive a pair of upper scissors matched with the U-shaped nozzle to move downwards, using the upper scissors in cooperation with a pair of lower scissors for cutting off the weft, and making a movable closed loop block move downwards at the same time to close the U-shaped nozzle so that the weft which is cut off can be isolated and left in the U-shaped nozzle where a closed loop has been formed; thirdly, making the electromagnetic valve control an air jet hole to blow air in the direction towards the weaving area after the weft push mechanism recovers so that waste weft materials which are cut down can be blown into the weaving area and the plane edge can be woven; fourthly, making the upper scissors and the movable closed loop block reset, and waiting for the next time of circulation movement.The operation method is simple.The requirement for the structure of an edge fold-in mechanism for plane edge processing of the corresponding cloth is low, and existing devices can be transformed to adapt to the method.The effect of the processed plane edge is good.
Description
technical field [0001] The invention relates to the technical field of looms, in particular to a weaving method for smooth-edged cloth on a shuttleless loom. Background technique [0002] Cloths woven by existing shuttleless looms are usually raw edges, but some cloths with special requirements require smooth edges. In order to meet the requirement of smooth edge, it is necessary to install mechanical fold-in mechanism on the shuttleless loom. These mechanical fold-in mechanisms are complex in structure, large in size, troublesome to install, and high in manufacturing cost, which also increases the purchase of loom users. The cost. In addition, the above-mentioned mechanical tuck-in mechanism cannot meet the weaving requirements of high-speed rapier machines and air-jet looms, and also has defects such as inconvenient adjustment. At present, there is a lack of corresponding methods for the smooth edge treatment of the cloth of the shuttleless loom. Contents of the invent...
