Problems solved by technology

The leno hemming device can not only solve the existing problems of the leno hemming device in the prior art, such as large and complex structure, short service life, and inability to adapt to high speed, but also can replace the rope-like hemming device, and solve the problem of high-speed shuttleless looms. Due to the use of continuous rope-like hemming devices, there are complex mechanisms, large loads, high noise, many wearing parts, high cost, and low reliability, or the use of discontinuous rope-like hemming devices has large energy consumption and manufacturing and high cost of use

Embodiment Construction

[0037] In this article, "left" and "right" refer to the left-hand side and right-hand side of a person facing the loom and standing in front of the loom, respectively, and "upper opening position" refers to the position of the shed triangle when the shed is opened to the maximum. The position of the upper line or the position of the corresponding components, "the position of the lower opening" refers to the position of the lower line of the shed triangle or the position of the corresponding components when the shed is opened to the maximum.

[0038] Such as figure 1 Shown in Fig. 3 is the first embodiment of the present invention, in this embodiment, leno hemming device 1 comprises a set of space link mechanism 2, and space link mechanism 2 comprises crank 3, bending shaft 4, Swing torsion bar 5 and connecting rod 6. Such as figure 2 As shown, the bending shaft 4 includes the main shaft 7, the auxiliary shaft 8, and the bending shaft gear 15. The axis line of the main shaft...

Abstract

The invention discloses a gauze edge twisting device (1) which is simple in structure and applicable to high-speed shuttle-less looms. The gauze edge twisting device comprises one or two rocking arms (5) doing spatial rocking motions and bending shafts (4) in quantity the same with the rocking bars (5). Each bending shaft (4) comprises a main shaft (7) and an auxiliary shaft (8), a bending angle formed by intersection or spatial crossing is set between the main shaft (7) and the auxiliary shaft (8), the main shaft (7) is connected with a frame through a revolute pair, each of the rocking bars (5) is connected with the auxiliary shaft (8) through a revolute pair, and the bending shaft (4) rotates or rocks relative to the frame around the main shaft (7) when the rocking bar (5) rocks around the auxiliary shaft (8). Under effect of the spatial rocking motions of the rocking bars (5), a first twisted warp (18) and a second twisted warp (19) are guided through guide holes (16) to form a gauze twisted edge.

Description

technical field [0001] The invention relates to a leno hemming device, in particular to a two-warp leno hemming device used on a shuttleless loom. Background technique [0002] The selvedge is an important part of the fabric, and its basic function is to lock the side warp yarns on the outside of the fabric to prevent the side warp yarns from loosening and slipping. The shuttleless loom needs to cut the weft yarn after the weft insertion is completed, so the weft yarn is no longer continuous at the selvedge, and burrs are formed on both sides of the fabric. In order to lock the side warp yarns on the outside of the fabric and prevent the side warp yarns from loosening and slipping, various types of locking devices have been applied. The types of hemming devices on shuttleless looms mainly include: leno hemming device, rope-like hemming device, folding-in hemming device, hot-melt hemming device, etc. Among them, the most widely used are leno hemming device and rope-like hemm...
