Background

As is known in the art, shedding devices for weaving looms are mainly treadplates, electronic dobbies and jacquard machines. After the shuttleless loom replaces the shuttle loom, the weft insertion mode is changed, meanwhile, the form of the weft fabric is correspondingly changed, specifically, the weft is discontinuous at the selvedge, so-called burrs are formed, and the burrs are easy to fall off because no effective constraint (restraint) is formed between the warp and weft yarns, so that the appearance and the quality of the fabric are influenced to a certain degree. If the raw edges are processed in the manner of cutting, hemming, sewing, etc., it is labor, time, material and increases the production costs for the textile manufacturer.

Selvedges are treated by special selvedge forming devices on shuttleless looms to form so-called reinforced edges, of which twisted edges are one type. Because the yarns have certain elasticity, the two ends of the weft yarn must be fixed before the weft yarn passes through an opening formed by the warp yarn during weaving to ensure the quality of the cloth surface and the smooth weaving, so the openings of the twisted edge parts at the two sides of the cloth surface must be closed before the middle cloth surface, and a special opening device is needed.

Further, from the above description and in conjunction with the knowledge in the art: the jacquard machine itself has a shedding function, i.e. it is a loom shedding device itself, and the selvedge device is also a shedding device. In order to ensure the quality of the cloth surface and the smooth weaving, the cloth surface of the twisted edge needs to be fixed firstly, namely the opening of the twisted edge part is required to be closed firstly, so that the weft yarn is fixed and cannot rebound before the next weft is carried out on the weaving machine, and the eccentric cam screw 37 can be adjusted according to the opening angle of the jacquard machine so as to reasonably change the relative positions of the first eccentric cam I35 and the second eccentric cam II 36 on the twisted edge shaft 31 and ensure that the twisted edge opening is closed firstly compared with the opening of the jacquard machine.
