Abstract

In a travelling wave shed weaving loom a chain (3) arranged below the rotary beating up blades (13) is provided with shuttle picking jib arms (17) which pass between the waves of the blades 13 and between the blades 13 and the dents of a separating reed (10). The dents of the reed (10) fit closely to the circumference of the blades (13), at least between the plane of the lower warp threads (23) of the shed and the weaving plane, the blades (13) are supported by rotating rollers (11) and the jib arms (17) are provided with rollers 18 which drive the shuttles (20). <IMAGE>

Description

This invention relates to a weaving machine with a wave-like movable throat.

A loom with a wave-like movable throat contains means designed to form a fabric, including a rotating reed, a distribution grid and weft yarns, which are moved by an endless cecy in the throat from the main threads.

There are several options for weaving. X machines with a wave-like movable throat. Versions are known in which between the wraped reed and raspredete. The cage has a much larger gap, in which the weft plotters are mixed. In rotary birch plates, where the surf edge sinks and leaves the base, there is a result of insufficient direction of the main threads between the wrench plates, e-state reed and distribution peineTKH plates, the overlap of these threads from one gap of the rotating bird to another that ) 1 causes tissue defects. The rotating reed has a relatively narrow groove in which the weft thread is laid, the exit is nuiH from the plotter so that it is nailed to the edge of the fabric. Often it happens that the thread is not inserted into the groove of the paving, not transferred to the edge of the fabric, leaving immediately behind the plotter. A defect arises, to eliminate which the weaving process must be interrupted. Known weaving shoe with wave-like movable throat, (Switzerland's LlaienT, LU H19274, class. 03 D 47/26, 1980), containing the weft arms of 1Stey, endless chain transport, to move the plotters inside of the main lines, installed with the possibility of lying | 1and bordo for dribbling the weavers, plastic_1 1 of which | 1ac1k): i) wiped women. innnn, set,; 1 fixed at 11, private distribution, lit. | on the grid for the main HHTeii and on the gate for the plotters, set to 1E with the possibility of contact with their lower part. With the aid of a proc, 1adc,: 1 e, partially on a rotating reed, partially in a direction,: 1 th Hievi channel, ob1) directly in the ny parts of the distribution grid. As a result of the formation of this channel, a gap arises between the Vaiyauni1ms Bird and the distribution grid, precisely at the place of the weaving plane, again a large gap allowing the break of the OCHOBHI IX strands at the moment the edge of the rotating reed penetrates. As a result, a considerable force, which is often necessary for pulling the plotter through the base, arises not only on the vampire reed, but also on the small slot and the shortening of the service life of the equipment. Vra cayuples

Because of its flexibility and low stiffness, pressure can be easily deformed during weaving. This leads to a slight deviation of the plotter's deviation and to an increase in its resistance during the nro passage through the distribution distributor channel. Therefore, the raised reed is supported by massive moving support shafts. Finally, it is necessary to apply special equipment, which at the entrance transfers the plotter from the endless chain to the rotating reed, and at the exit transfers the plotter from the lying reed back to the endless chain.

5The purpose of the invention is to improve the quality of the tkapi by reducing the possibility of cutting it.

/one. I achieve this celil- ranporter located under the reed, while the guides for the plotters of the assembled ny of the links of the conveyor chain so that they are located in the hollows of the reed helix during its rotation, and the plates of the distribution reel abut on the contour of the reed at least in the area mezh5 DU line dredging machine and the plane of the lower branch of the throat main threads.

On the frame 1 of the weaving shoe, attach 5 pa1a 2 directions for an endless lenn conveyor, connect the connector.: 1 with 3 axles, on which you oscillate,: расп расп, 1) 1 link 4. At both ends, connecting pins 3 provided with pedal rollers 5 guiding the stump.

0 Against the fallout, the chain on the other hand has 3 support rollers 6 in the middle part of the trunnions, articulated by means of the shanks 7 in the holder 8.

The holder 8 is fixed on the frame 1 of the stack and in its upper part is provided with a distribution grid formed by the frame 9 in which the plates 10 are fixed. Between the frame of the distribution grid and supporting rollers 6 the holder 8 is provided with a notch for a vaginal fit

The plates 10 of the grid; 1n () of the lattice are parallel and at the same distance, as well as the section 13 of the rotating D) e) and are longitudinally deflected from the axis. From the side of the rotary blade of the Iflast base plate, P1 111 is a convex but circular curve 16 corresponding to the outer contour of the side of the body, from which the plates 10 closely adjoin their convex part. The links of the infinite penny 4 with their lower ends are attached to the harvesters of the plotters - stre: 1, 17, passing between the spiral lines of the spiral line, formed by the plates 13 and the plates I) of the distribution grid and are equipped with drive rollers 18 at their upper end. The drive rollers 18 drive the driven rollers 19, which are located vertically on the plotters 20 of the weft thread 21. The plotters 20 lie with free arrows on the arrows 17 that move them through the open mouth 22, formed upper and lower main threads 23, controlled by galev 24, located but sekny m in columns 2G). 11p () to: the handlers 20 are supported on top by a folding stop bar 26. Pa of the pharynx 22 are located on the created fabric 27 1 of the 2H paring.

The operation of the machine is as follows.

When launching a weaving stack with the help of a non-depicted zvudo.podochig- in the movement of an infinite chain. (.) rotates the rotation of the reed synchronously, synchronously ((/ warmers 17 are fascinated by the lines 4 of the endless chain) and through the driving and driven rollers 18 and 19, the windrowers 20 are set in motion. B) the waves by the surfboard edges 14 of the plates alternate 13 forward and continuously moving forward along them the boom of the boom 17 with the plotters 20. And the wave-like movable mouth 22 in front of them gradually opens and closes behind them, and the weft thread is nailed by the next wave of the rim edges 14 of the plate 13 with the plotter 20. to the fabric of the fabric, where peg stranded with the new yarns 23, with the formation of the following throat 22 d, t sat, 1: the next plotter 20. A pair of the main yarns 23 meets the top 15 of the surf edge 14

the main yarns 23 are therefore separated directly by the WB, the plasticine 10 paciquMe tel lattice, which ensures their exact direction and prevents them from moving to the other 13th liebeard 13 plate. In order to prevent the wedge from retaining it, it should be underneath by the supporting rollers 11 that lie with it. Pickers, after engaging the drive and driven rollers 18 and 19, are mounted from above with

With the aid of the support bar 26, which can, if necessary, be n (M1 1 arm (jcHOBbi fold back).
