The invention relates to the knitwear industry and is intended for household appliances in hall machines used for knitting apparel in household conditions.

The aim of the invention is to improve the ease of maintenance of the machine.

Figure 1 shows the machine offered in the batt, a section along the carriage and needle bed; figure 2 is a view of the carriage from the side of the wedges; on fig.Z - view along arrow A in figure 1; Fig. 4 shows the construction with installation on axes x located closer to the middle of the carriage, two po, faces; figure 5 - section bb in figure 4; Fig. 6 shows a hinged construction of the axes of the rollers; figure 7 is a view along arrow B in figure 6.

A household machine contains a needle bed 1 (Fig. 1), in the slots 2 of which the tongue needles 3 are placed. On the rails 4 fixed on the needle bed the carriage 5 can move. On the carriage a bracket 6 is fixed, to which the corners are attached 7 - 9 s the axes K) - 13, which are locked on them (Fig.2). Gear wheels 14 - 17 are installed on the axes, each of which is made in the form of a truncated cone (FIG. 3), roller teeth 18 are formed by a conical surface 19 and a flat surface 20 on the larger base of the cone. The rollers (figure 2 / turned the apex of the cone down towards i opposite from the needles 3.

Axes 10 and 12, located closer to the middle of the carriage, are inclined in two planes. The angle of inclination oi to the axis of the needle groove (Fig. |) Lies within 50 - in. The angle of inclination and FIG. 3 to the plane of the carriage wedges is between 59 and 79. The rollers 14 and 16 are located in the zone between the end 21 of the platform 22 of the curling wedge 23 and the point 24, corresponding to the exit of the axis 25, the needle tongue 3 to the level 1 of the front edges 26 of the fender teeth 27 of the case 1 at the intersection of the front edge with the bottom of the needle groove 2. The point of the axis of the axis to the level of the front edges of the bog teeth is located from the front edge of the bog teeth at a distance K (Fig. 1 and 2) equal to the size of the needle to the axis little tongue.

 1 Axes 11 and 3, mounted closer to the edge of the carriage, are inclined at an angle K in FIG. 1 to the axis of the needle groove.

The angle J is in the range of 66-85. Each of the rollers 15 and 17, mounted on axes 11 and 13, is located against the working edge 28 of the wedge 29, in the area between the points 30 of pressing and the conclusion 3i. The pressing point 30 is located at the intersection of the inclined edge 32 of the lifting clip 33 with its edge 34 located at the level of pressing.

On the machine, designed for the boom extruded weaves with a large number of sketches, it is possible to manufacture a carriage (FIG. 4), in which two rollers 37, 38 and 39, 40 are installed on axes 35 and 36. The cones Bepnraffiii of polishes 37 and 38 are directed in different directions, the top of the cone of the roller 38 is in the direction of the needles, and the top of the cone of the roller 37 is in the direction opposite to the needles.

The structures shown in Figures 6 and 7 are designed for use on machines with a large range of the length of the loop produced by the knitwear. Axes 41 and 42 in their lower part are equipped with flats 43 and holes that include a finger 44 attached to the bracket 45. Axis 41 and 42 spring spring 46 and mounted on the finger 44 hinged with the possibility of rotation. The upper ends of the axles 41 and 42 are pressed to the bevels 47 of the strip 48, rigidly fixed on the wedge 23. 23.

Ma.shina works as follows.

When the carriage 5 moves along the rails, the 4 needles, moving along the path defined by the wedges of the carriage, form loops. The rollers are engaged with the end teeth 27, and when they are twisted, the carriages rotate around their wheels. When the carriage moves from left to right, the roller 16 rotates (Fig. 3) and due to the inclination of the axis 2 pulls the loops down, not allowing them to move following the needle, rising to the end. The roller 17 holds the hinges near the leading edges 26 of the baffle teeth 27, ensuring reliable loops of loops from the tongues of the needles to their rods.

when the carriage is moving from the left, for example, by retaining and holding the loops, rollers 16 and 17 are produced, while moving the carriage from right to left, these operations are performed by rollers 14 and 15.

"

In the case when a knitted fabric of the same fabric or a press weave with a large number of sketches is used on the machine, the design shown in FIG. 4 is applied. As the carriage moves to the left, the roller 38 rotates, snaps into the teeth and teeth and pulls the knit loops at the point of needles to the level of the front edges of the breaker teeth at the point of their intersection with the bottom of the needle groove. The roller 15 is rotated in the area between the pressing and closing points, and the roller 37 is rotated between the rollers 15 and 38, affecting the loops that come out of contact with the toothed rollers 38,

pulling them away and keeping them from following the needles.

In the case when the machine has a very wide range of density changes and the displacement of the kulirny klein to a large value, the construction shown in Fig.6 and 7 is used. When the kulyrnogo wedge 23 is moved, it is rigidly fixed

On it, the strip 48 moves in one of the directions indicated by the arrow in Fig. 6 (with an increase in the length of the loop - to the right, with a decrease - to the left). At the same time, C1; wasps 47

5 strips 48, acting on the upper ends of the axes 41 and 42, rotate them relative to the finger 44, changing the angle of inclination of the axes. When knitting with a long loop

The tilting of the axes is increased, thereby making the loops protruding by a large amount, while knitting with a small loop length is reduced, the tilt angle of the axes is reduced.
