Description

A known weaving machine with fabric-forming discs mounted on a common shaft, including a device for laying the weft yarn, provided with a moving perforated tape with a clip. For gripping the end of the weft thread from the reels.

The described weaving machine as compared with the famous boggey is productive. This is achieved by the fact that the perforated tape is driven from eight spike rollers, which alternately drive the tape and receive rotation around their Axis. The axes of the rollers are reinforced four on gears, mounted on the shaft of fabric-forming discs, having four spiral-shaped longitudinal grooves inside to direct the perforated tape to the corresponding roller, and the boomers are mounted on the cross, also mounted on the shaft of the fabric-forming discs.

. ., FIG. 1 shows a kinematic design of a weaving machine; in fig. 2-- technological scheme of refilling the machine.

From the motor / through the V-belt transmission, the rotation is transmitted to the gearbox 2, which through a pair of tapered shchy | Steren 3 and 4 and the pin roller 5 communicates the movement of the continuous perforated tape 6 with the scanning eye 7, which unfolds the continuous weft thread. Rollers 8, 9 and 10 are idle. Through sheyterni 11 and 12, the shaft 13 receives rotation, on which the tissue-forming disks 14 15 15 n 16- are mounted.

The discs M serve to form the lower branch of the shed of the base and have grooves for guiding the perforated tape laying a non-continuous weft thread. The disks / 5 serve to form the upper base of the base and have grooves for the passage of a discontinuous weft yarn laid with perforated tape 17. The disks 16 for making the weft yarn and have grooves for the passage as interrupted 120771-2 -

both HcnpcpbiBiibix weft yarns. The configuration of all the disks ensures that when they are turned, a creeping pharynx is obtained, which makes it possible to carry out the laying of wefts during the rotation of the disks.

The drive of the perforated tape-U / carried out from eight spiked rollers / i, located on; Four on each side of the e-tank. The axes of the roller rollers 18 are fixed on gear 12. The rollers 18 receive rotation around their axes through a fixed conical bristle /.9, a movable conical jaw 20, two partig 21 and 22. cylindrical bristles and a roller 23, which through a system of bevel gears (on the diagram is not shown) informs the rotation of the rollers 18- On the shaft 13, the crosspiece 24 is fastened, on which four reels 25 are mounted. two branches and enters the fabric shaping discs. The tape / 7, which performs a longitudinal-rotational movement, passes through the grooves of the tissue-forming disks / o. And has a grip, by means of which a discontinuous weft thread is captured from one of the four reels 25. The weft is cut when it strikes the cutter 32. Return tape 17 is carried out through the spiral longitudinal grooves 33 of the shaft 13, which provide rotation of the tape, and moving it to its original position for submission to the subsequent shed.

As a result of rotation, along with the disks of the rollers / 8, advancing the belt 17, an increase in the time for laying the intermittent weft yarn is achieved. A continuous weft yarn, reeled off the reel 34, passes through the nitate resident and the fixed eye 35 into the hinged eye 7 of the continuously moving belt 6, which spreads the thread onto the smooth surface of the discs between the two QCHOBbi branches. In the process of rotating the discs 14, the thread is caught in their grooves and retractable grippers 36.

The finished fabric enters through the breast 37 per tonne of the platen roller 38 and the roller roller 55.

Subject invention

A weaving machine with cloth-forming discs mounted on a common shaft, including a device for laying a weft yarn, equipped with a moving perforated tape with a clip to grip the end of the weft thread from reels, in order to increase the productivity of the equipment, the perforated tape is driven from roller rollers, for example, eight, alternately driving a belt and receiving rotation around their axes, mounted four-by-six on cogwheels, mounted on the shaft of a cloth-forming disk in having four inside spiral longitudinal recess for guiding the tape to a corresponding perforated roller, wherein the bobbin mounted on the crosspiece, fortified also drives the shaft tkaneformiruyuschih -;
