The expanding y -producting wedge (Fig. 1) consists of a plate 1 with two columns 2 designed for

fixing the wedge on the rail yarn feeder. In the front part of the plate 1 there is a working surface 3 with bevels 4 and 5. On one machine it is advisable to use a number of such wedges that differ from each other in the length of the working surface 3. Depending on the length of this surface and the installation location of the wedge and their number the location and extent of the area depend, the liner and the sleeve do not rotate in a bypass. These areas are filled with loops of a certain color.

For the installation of all types of patterning wedges, throughout the entire length of the yarn guide rail, holes are drilled with minimum pitch, in which the stands of 2 patterning wedges enter. To be able to install pattern-forming wedges anywhere on the rail, it is necessary that (L

the distance between the uprights 2 was a multiple of the pitch of the holes in the rail.

The patterning wedge wedge (Fig. 2) consists of a plate 6 with struts 2. A plate 7 is mounted on top of the plate 6. This plate can be moved relative to the plate 6 and screws 8, which are rigidly mounted on the plate 6 and serve to guide the movement of the plate 7. For the same purpose, the plate 7 has grooves. On one side, this plate has a working bevel 9. On one machine, it is necessary to use inclining pattern-forming wedges with a different arrangement of bevel 9 and the reverse slope of the slots. Thus, in addition to various sizes, inclining pattern-forming wedges can be either left or right.

FIG. 2 shows the right pattern. wedge This wedge consists of a plate 6 with posts 2 for mounting a wedge on a rail. On top of the plate 6 is a plate 7 with a single bevel 9 of the working surface. Plate 7 has inclined grooves that allow it to move relative to plate 6 and screws 8, which are screwed into plate 6. Racks 10 and 11 are used to return the plate 7 after it has been reset to its original position. on plate 7, and stand 11 - on plate 6.

The tapering pattern-forming wedge (FIG. 3) consists of a plate 13, in front of which teeth 14 are cut. On top of the plate 13, a wedge 1b is fixed with screws 15. Racks 2 fixed in plate 13 are used to install a narrowing pattern-forming wedge on the thread sub-rail rail.

A sleeve with holes for the threads is used to quickly change the total initial rapport width of the pattern (Figure 4). The sleeve is used in place of the upper liner and pulley of the thread guide tube of the known device. The device is equipped with several similar sleeves with different diameter D.

power racks 2 rail 17, with the axis 18 of the drive roller 19. This roller rotates freely on the axis 18. In the middle part, the drive roller 19 has a groove under the drive belt 20, which causes the sleeve and the insert with the holes for the threads to rotate. Axis 18 is firmly fixed to the strap with the help of a nut 21. This strap is freely mounted on the yarn feeder and, using a special spring (not shown), keeps the drive roller 19 in contact with the rail 17 of the yarn feeder. Thus, in the absence of 17 pattern-forming wedges on the rail, the drive of the sleeve and the insert with the threads is in an operating state. When the axis 18 interacts with the working surface of the expanding or tilting wedges, the drive roller 19 interacts with the stop 23. This stop is rigidly mounted on the yarn feeder pad and is designed to prevent the spindle 19 from spinning spontaneously during idling of the yarn feeder. In the upper part, the drive roller 19 has a gear gear 24. This gear (FIG. 6) is designed to interact with the teeth 14 (FIG. 3) of the plate 13 of the tapered pattern-forming wedge.

To remove the roller 19 from the rail 17 and the correct orientation of the gear 24 relative to the teeth 14, use a wedge 16 mounted on the plate 13 with screws 15. This wedge will work with its working surface on the axis

18, disengages the roller 19 with the rail 17, and the movement of the axis 18 is calculated so that the roller

19, coming out of the interaction with the rail 17, does not interact with the stop 23 (FIGS. 3 and 6).

The sleeve 25 (Fig. 7) is mounted on the upper end of the tube 26 and is locked with a screw 27. Thereafter, a drive belt 20 is threaded onto the groove in the sleeve. The bar 22 (Fig. 5) at the attachment point of the axis 18 has a pack (not shown) allowing after heading the nut 21, move the axis 18 along the rail 17, which is necessary for tensioning the drive belt 20 after long-term operation and changing the sleeve 25 (Fig. 7). After tensioning the belt

20, the nut 21 (FIG. 5) is tightened, fixing the axis 18 in a predetermined position

Figures 8-14 show the possible variants of the patterns that allow obtaining the device using various types of pattern forming wedges and combining them together.

So, for example, the drawings in Fig. 811 and 13 MAY BE POSSIBLE AT IC-

using the expanding and tilting wedges, the drawing in Fig. 12 - using the expanding wedges, the drawing in Fig. 14 - using the expanding and narrowing pattern-forming wedges.

The device works as follows.

When moving on the rail 17, the roller 19 (figure 5), in contact with its surface, rotates the liner and the sleeve of the yarn guide. If an expanding wedge-shaped wedge 1 is installed on the path of movement, then it, acting on its working surface 3 with the speeds of 4 and 5 (Fig. 1) on the axis 18, disengages the roller 19 from engagement with the rail. At the same time, the sleeve and liner stop rotate, which allows to obtain on the canvas a plot of a given color. The position of the sleeve and the liner is fixed by the stop 23. After the axis 18 leaves the interaction with the wedge 1, the rotation of the sleeve and the liner resumes as the roller 19 comes into contact with the rail 17.

If an inclining wedge occurs in the path of the drive unit, the following occurs. By acting on the axis of the drive roller with a bevel 9 of the working surface of the plate 7 (Fig. 2), the tilting clip stops the rotation of the drive roller. During the reverse movement of the yarn feeder, the drive roller axis, acting on the step 7 of the plate 7, discharges the plate, shifting it into the grooves relative to the screws 8. At the same time, the initial ROIIC does not stop its rotation, since in this case it pulls out the HP from engagement with the rail.

The right pattern wedge allows any inclination and various locations of the pimp. With a double yarn guide, this wedge is blind; the wedge stops the wedge of the salary and the stump, and when moving to the right, the palenus ml and 7 turns off, and

Water rotation of the liner and bushings is not interrupted by its own work.

The action of the left tilting wedge back to the action of the right.

If a narrowing pattern-forming wedge occurs in the path of the drive device, the device operates as follows.

The wedge 16 (FIG. 6 and 6), acting on the axis 18 of the drive roller 19, removes the roller from engagement with the rail 17. Thereafter, the tooth 14 of the plate 13 comes into contact with the gear 24 of the drive roller 19. A quick turn of the drive roller 19 occurs, and ultimately the rapid rotation of the sleeve and liner with the threads. This reduces the blurring of the borders of the color bars and the width of the bars themselves. At the same time, the drawing acquires clear boundaries in the place of installation of the narrowing wedge. The amount of rotation of the drive roller is determined by the number of teeth 14.
