Description

Close to the sponge is supplied with ItenaPra, in: it-ate € M, (located at the end of the weft yarn directed to the source, nourishment.

The grip has a 1nutical pointed sponge / rigidly connected to a rapier (not shown) and a turning sponge 2, which sits on axis 3. Sponge / I1 has a hook 4, .withrein surface 5 of which is solr. a female with a surface 6 of the swiveling jaw 2 and between the shihs there is a gap between them, narrowing towards the point of the fixed gubzhi. Contacting of the adjoining (surfaces is carried out due to the spring 7. The movable sponge 2 is equipped with a cam lug 8 for engagement; also: with the control body of the machine. On the fixed sponge 1 to be installed {straightener etch 9. Conjugated friction 5 - cool-ach 4 hl 6 - the jaws 2 are preferably screw-shaped with a decreasing angle (called the pointed jaw in the side of the stationary jaw. Figures 2-5 show some versions of .noBepxiHOCTCM 5 to 6, where the surface 5 is always flat, inclined relative to horizontally The second plane in the direction of closing the grip, and the surface 6 1M | Ozhet; AND | Mark the various Bapinants of the performance.

Z-grab works as follows.

With its pointed h-side with: hook: mop passes, into the feed grip and moves back after the daily thread forgives noBeipx zryuchka 4. When the gripper is reversed, the yarn thread bursts between 1PS1 top1 5 hooks 4 and the surface 6 of the rotary shaft 2. The entrance of the weft yarn between these two surfaces, which takes place. From the beginning only under the air generated by the load gripper. This tension is directed in the direction of the arrow R in the opening зах opening (see Fig. 7 and 8). After the end of the weft yarn comes out of the feed grip, the following applies to it: about the tension created by the tensioning devices and the feeding reels. This tension is directed along arrow F (see Figs. 7 and 8) and acts in the direction of closing the grip. This ensures that the clamping 1I; pr101Cladding; N | Ie the weft thread, (because there is a grip (It works as a self-zap. Than

prevents the possibility of thread loss in the throat. This effect of samozagirani is improved with the use of the thread guide 9. Zakh1vat in the normal position is compressed

The ino engagement of this invention allows both thick and thin weft yarns to be laid. The gripping action ensures efficient operation with alternate laying of weft yarns of various thickness.
