Description

(54) DEVICE FOR RIPPING THE DECK OF CUTTED CHORD

The longitudinal surfaces of the hollow cylinder 8 are made and then three rows from each end of the cylinder. The hollow zilin-dr 8 has flanges 9. To the ends of the hollow cylindrical 8, there are attached undercuttings of 10 to 11. Caps of lodshilnikov are closed with lids 12. On the left corulus: spike 10 is mounted on the starPEN 13 by means of the slider 14.

The mechanism for tearing the weft also contains 5 thin sheets 15, 16 and 17 assembled on a cylinder of a cylinder, the thickness of which is approximately equal to the thickness of the thread of the cord being processed. Each lusty has a projection 18 along the edges of the DZA, and their distances from the ends of the plate are different. The difference between the distances of d-voh adjacent llastins is somewhat greater than the width of the protrusion 18. The protrusion width at the ends of the plastane and the difference of distances from the ends of the plates to the protrusions in the two adjacent plates has a ratio of, for example, 1: 1.2.

Plates 15, 16 and / 7 are installed in cut and by means of the protrusions 18, the sequence of alternation of the plates is observed; in the same order. The protrusions 18 interact with the eccentrics. 5 l relate to the last distances of different distances from the end of the eccentric, and thus all the protrusions 18 of the plates 15 are disposed at the same distance, the plastine 16 on the other m and the plastic / 7 on the third. This way it is allowed to have. plates, closely adjacent to each other, are the outer surface of the cylinder 5. At the same time, on the eccentric 5, the projections 18 do not touch each other, allowing the lasters to move freely in the radial direction. To keep the plates pressed, the eccentric rubber is provided to the eccentric. 19. The asterisk 13 is connected by a drive chain 20 with an asterisk 21 1 on the motor: re, do-22.

On the frame / fortified two racks 23, on which freely rotating rollers 25 and 26 are mounted in Kodas 24 24. Two ratchets on 27 are mounted on the same bed, in which there are slides 28 in the slider. tensioning roller 30, which turns on the help of screws 3.1.

For Lrizhati rubberized cord 32 "plate-m 15, 16, 17} the device is equipped with an endless rubber band 33, put on a roller 25, 26 and 30.

ycTipoECTBo. works as follows.

A cord 32 with threads 34, arranged parallel to the axis of the hollow cylinder 8 and with a weft 35 connecting “it and 34” is fed into the gap between the upper part of the slider 8 with the plates and the rubber band 33. Distance. “Between the strands of the horde is equal to. as

in the upper part of the plate fits snugly around each other and the thickness of them is approximately the same thickness of the thread, it is natural that each thread falls on the upper plane of the plastilla immediately zap.iks: it is pressed on it to press the Mash tape 33. Pressing It is determined by the tension of the role. In such a way that when the weft is broken to pour: it cannot slip off the plate. With further rotation of the hollow cylinder 5 of the shaft 3 from the gear motor 22, the threads move with the plates, and the rubber tape 3k is drawn by this movement in the same direction as the cord 32. When moving the plate along the ECCE They move relative to the center of rotation and the radius r increases to size R by the value of two eccentricities, e. The increase in radius in the mellow area is 100-26, .nli is% The distance between each plate when moving them from upper position to lower position. For a galloping rupture of a hard-nosed duck, this slice is taken in the range of 30-40%. If the step between the nitas. Mi at the entrance is equal to b, then at the output it is equal to,, larger relative to b by 30-40%. This percentage of step stretching does not exceed the elastic limit of the raw rubber, which binds the thread to the binder, therefore, over a long period of time, the step decreases to the original b.

The technical effect of the proposed arrangement is to improve the quality of the horde going to build tires of a radical design, as a result of which the line length increases and decreases the marriage, which with a solid weft is quite great. TO.
