FIG. one

This invention relates to tension | devices for weaving machines controlled by the jacquard mill.

The purpose of the invention is to increase the long eternity and reduce the load on arctic ishurs by using tensioners with lower power characteristics.

FIG. Figure 1 shows schematically the structure of the proposed tensioning device; on (lig. 2 - layout of additional elastic elements in the unified node; l Lig. 3 - connection naphpl of your tubes and plate; in Fig. A - the same, another form of execution; on Lig. 5 - the same as Fig. 4, with a preliminary tension of an additional elastic element.

FIG. Figure 1 shows a schematic arrangement and arrangement of the jacquard machine I with respect to the loom W. The warp threads 1 passing through the loom W can, by means of an appropriate arcade cord 2, obstruct the throat. To remove the warp threads of 1 liter of zepa, the cord is affected by a 3-nlt tool, shown schematically with a spring, creating a force F1 in the direction 1 to the machine tool. In Jacquard m .-. Pnne I, the hooks in accordance with the program move between the POSTRY OF the upper and lower throat branches and stop depending on the pattern in one of two positions. Each hook 4 is connected through a frame cord 5 to at least one single cord 2 of the weaving loom W, for example, by means of a carabiner and loop, which are located at the corresponding end of the frame cord 5 and, accordingly, apw of the cords pmura - lks: two position can

carried out in a known manner. one

In the position of the lower shed branch, the lower end of the hook 4 rests on the sieve 6 of the Jacquard machine T., which is fixed in the frame of the machine.

With one hook 4 (tbnr. 1) several arcades of cords .1 can be connected to form a predetermined rapport interlacing. Such arrangements are common and known. The arkaty cord 7. passes through the direction of the yupne, which are connected to

us These lines should not be parallel to one another due to the overcrowded extreme arcade cords on the cuscium board 7.

The reset force acting on the hook and the warp thread must meet certain conditions. If this force is too large, wear is too great, if this spring force is too small, functional disturbances may occur.

This problem is solved with the aid of a unified unit F containing a spring-generating element. According to FIG. 1 unified node. F has a face 8, which can be firmly but detachably connected on one side with the frame cord 5, and on the other side with the arcade cord 2. The face 8 carries the stop 9. Between the stop 9 and the plate connected to the machine frame 10 s The holes provide an additional elastic element 11, which creates a spring force G 2. The latter is determined in such a way that it is enough to feed the hook 4 down. The force g 1 of the tension means 3 is designed so that it is sufficient to feed the lower branch of the yarn. warp 1 if the corresponding hook 4 is driven in the lower position. Thus, the force r - created by the element 11 is determined regardless of how much the arcade should be lifted and, accordingly, lowered with a single hook.

As for the jacquard machine T and the loom V a number of elements 11 must be arranged in accordance with the arrangement of the hooks 4, it is advisable to provide a guide tube 1. with the same arrangement, with element 11 in the guide tube, ramepusht, faces 8 and stop 9 (Fig.). The guide tube 12 is rigidly fixed between the top plate 10 with the holes and the other plate 13 with the holes. The guide tube 12 may be thin-walled if both plates 10 and 13 are mounted on the frame of the machine at a predetermined distance from one another. Nl FIG. 2 shows the approximate arrangement of the holes 14 in the plates 10 and 13, necessary for the passage of persons 8. Depending on the arrangement of the hooks 4 in the jacquard machine T the holes 14 of adjacent rows

can be located one more displaced one to LGU g mu. LLKM- placing coins to allow adjacent guide tubes 1 2 to touch one another, Face 8 (Lig. 2) has a carabiner 15 at the upper end, and a loop 16 at the bottom, however this arrangement may also be reversed depending on how equipped frame cord 5 n arcate cord ..

FIG. Figure 3 shows an arrangement in which an additional elastic element 11, designed as a coil spring 17, is fixed to a plate 10 with holes. Hole 14 for the passage of the face B has basically only a slightly larger dilmeter compared to the diameter of the face. However, on the side of the guide tube 12 in the plate, a recess 18 is provided, the diameter of which corresponds to the outer diameter of the guide tube 12. Between the end of the guide tube 12 and the bottom 19 of the recess 1J, the last turn of the spring 17 is clamped so that when the spring moves, it is impossible for him; to-

A recess 1B is also provided on the other side of the plate 10, which serves to place the corresponding end in it with the direction tr. 12, but a plug 2 ° is inserted between the guide tube 12 and the bottom 1e of the recess 18. with a hole that is intended to pass the face 8. The plug with the hole serves as a fastening element for the spring 17.

The support on the face 8 inside the guide tube 12 is made in the form of a washer 2, the latter, in its outer diameter, fitted to the inner diameter of the guide tube 12 and may have openings for the passage of air. Therefore, washers 21 should be made in the form of asterisks, etc.

At the other end, the guide tube 12 is likewise secured in another plate 13 with openings. However, since there is no need for support for this from the side, it is sufficient to provide a hole 22 equivalent to the hole 14, as well as a recess 23 equivalent to the recess 18.

In order to prevent buckling of the guide tubes 12, it is advisable to provide a support plate 24 with holes, which has corresponding through holes 25, fitted to the outer diameter of the guide tube 12. The support plate 24 with holes is placed approximately in the center of the compressed spring 17, m. e., approximately in the upper third of the meddu space, with both plates Yu and 13 with holes. A support plate 24 (Lig. 5) with holes is connected to the bottom plate 13 with holes by means of a bolt joint 26.

The hook moves between the lower and upper positions, and in the southern position the lower end of the hook 4 rests on the grill 6. As shown in FIG. 4, the arrangement is such that in this lower position and the loop 16 lies without tension on the plug 20 (respectively, on the plate. 10 g holes in the shape of design B respectively: it is shown in FIG. 3) I upper; ° faces 8, which corresponds to the upper half of the hook 4, with the maximum of G2 maximum. The stroke h between the lower position and the upper position o is the value specified by the base of the warp on the machine.

FIG. 5 shows the same layout as on the league. 4, when located in the frame of a unified unit F, consisting of two plates 1 G1 and 13 with holes, and the melting is established between these plates by elements, creating an elastic force. A unified unit F is fastened between the upper part of the frame 27 of the jacquard machine I and the lower part of the frame 23 of the weaving machine with the help of the bolted joint 29. This shows that the layout according to the invention is mo. Can be used in existing jacquard machines and looms without changing them.

Unified node G (in comparison with Fig. 4) is planted deeper by the value of t due to the fact that between

top of frame

and plate

with holes 10 there is a space of 7170

exact detail 30 thick t. By selecting the thickness of the intermediate part 30, it is possible to additionally achieve pre-tensioning in the lower position and in the upper position on the spring 17, i.e. with one spiral spring 17, the force F2 can be varied.

According to the invention, the spring 17 is compressed in the upper position and the pressure force F2 applied through the plug 20 to the face 8 acts downwards. This arrangement may also be such that

 the upper position of the spring element., so that jacquard

will be stretched, and the force F2 will also act down. Other types of springs can also be used.

The jacquard machine with the tensioning device is operated in a known manner.

The machine has two plates located across its entire width with holes, and the guide tubes are located between them and the ends attached to these plates in the holes.
