Description

We do not have axis II and carriers of roller 12, all together with a cam disk 13. The cam disk is not a shaft 14, with a main rate connected to the main shaft. The pulley; / 3 is connected through a watering belt 15 to a pulley 16 sitting on the shaft of a stationary electromotor 17 connected to a power source. Before ; The tea bag containing the straight bolts 3 and 16 in the belt 15 is a co6oib means for rotating the roller 2. The RoStage 1 is formed by a tubular element (see Fig. 7), inside which an axis 18 passes. The shaft 18 is mounted in two ball bearings 19. Not one axle of the axle by means of the nut 20 and the cotter pin 21 is fixed to the roller 2. The roller 2 has an annular groove 22 for the passage of the weft yarn. The other end of the axle 18 carries the pulley 3.

At the end of the lever 1 facing the roller 2, a flange 23 is fixed with two sectors 24 and 25, each of which partially covers the roller 2 with a radial clearance that is less than the thickness of the final thread. Sector 24 overlaps the part of the path that the weft thread passes in the area of roller 2, thanks to the possible exit of the weft thread from the frame 22. Sector 25 has a stop 26, which comes with a side and radial clearance in the part of the rope 22 that is not covered by the thread. The restrictor prevents the slack weft yarn from being wound on roller 2.

The compensator is made of two pulleys 27 and 28, covered by flexible elements. belt 29. Pulleys are located on a vertical bar 30 fastened to the console 31, On one shaft with; pulley 28 sits up, an optional pulley 32. The latter, through belt 33, is connected to terminal 34, which is not mounted to shaft 35 connected to the machine's lead. The roller 2 is mounted on a support 6 fixed on the belt 29. On the shaft po-i of the face 2 there is a friction wheel 37, which is attached to the guide 38 located on the beam 30. The flanges of the guide Sv; C-pe are pressed to guide the friction wheel, 37, which has a smaller diameter in alignment with the diameter of the roller 2 and is set in motion when the belt 29 is moved.

The device compensates a weft yarn reeled from a reel 39,

on a bobbin holder 4O, aakrv- ". mounted on frames" e 41. On the same frame there is a stand 42 with an eye for nap. board 1.LTYa. On the way of movement of the weft g: Ш1ТИ a brake 43 and rollers 44 and 45 are installed to jffiHe.

The device works as follows. The weft thread, unwinding from the reel, grows in Pivsa loop between the loop and 44 and 4S of the collar. During the period of time provided for removing and stretching the weft yarn, the brake, yarn is released. During the work cycle, the lever 1 is turned. MojKeT can be provided with two roars ira 1 (see Fig. 3), on a roller of which the TG is fixed 2. The roller 2 moves from the upper position to the lower one, providing the flow of the drawn loop to the yoke. Ozi at the same time with the specified movement takes place the rotation of the roller. At the same time, its circumference for speed must be greater than the maximum speed of movement of the weft yarn.
