Abstract

The invention relates to a knit machine industry, namely to needle designs, and allows for increased reliability in operation. The width of the needle in the wide part of the rod exceeds the distance from the end of the tongue, which is turned perpendicular to the rod, to the needle back by a value of 0.2-2.0 mm. In the wide part of the needle core, a cut is made on the side of the back between the heel and the shoulder, the size of which exceeds the width of the carrier, as well as mutually perpendicular grooves. 8 il.

Description

The invention relates to a knit machine industry, namely to the design of needles.

The purpose of the invention is to increase reliability in operation.

Fig. 1 shows the means for forming and transferring loops, side view; Fig. 2 shows a needle mounted in a needle disk, section A-A in Fig. 1; in Fig. 3, a means for forming and transferring loops, top view; in FIG. 4, a needle without a carrier, side view, on the other hand; figure 5 - section bb in figure 4; figure 6 is a section bb In figure 4; on .fig.7 - carrier, side view; on Fig - the same, top view.

The means for forming and for transferring the loops (Fig. 1) on the circular machines consists of a tongue needle 1, a tongue 2 and a detachable carrier 3 and is installed in the asymmetrical slot 4 of the needle cases (Fig. 2).

The tongue needle 1 (Fig. 1) has a rod 5 with a wide 6 and a narrow 7 parts with a transition of the contour of one part to another at a right angle forming a ledge 8. On the wide part 6 of the rod 5 there is a heel 9. The narrow part 7 ends , the hook 10, and on the side surface 11 of the needle 1 (FIG. 3) there is a groove 12 (FIG. 3.6). The edge 13 (FIG. 1) of the wide part 6 of the rod 5 on the side of the hook 10 when it is extended to the line 14 is located above the back 15 of the pin reversed perpendicular to the back side 15 so that the width H of the wide part 6 of the rod 5 exceeds the size h from the end of the tongue to the back needles on the size of the gap d 0,2-2 mm. In addition, the wider part 6 of the rod 5 of the needle 1 is provided with a cutout 16 on the side of the backrest 15 between the step 8 and the tip 9, and on the side surface 17 (FIG. 3) opposite to the side surface 11, grooves 18, 19 are made (FIG. 4 , 5) with the same width B and depth hi, located perpendicularly relative to each other.

The detachable carrier 3 (FIG. 1) is made in the form of an elastic plate, the rod 20 of which is provided with a pin 21 bent away from the plane 11 (FIG. 3) of the rod 5 of the tongue needle 1, part 22 with the tip 23 (FIG. 8) at the end and inclined sections 24, 25. The tip 23 of the detachable jumper 3 enters with

elastic pressing into the groove 12 (Fig. 3,6) on the side surface 11 of the narrow part 7 (Fig. 1) of the rod 5 of the tongue needle 1, and the inclined section 25 (Fig. 8) passes through the notch 16 (Fig. 1) on the side side 17 5 (FIG. 3) of the tongue needle 1, rod 20 with heel 21 are installed in mutually perpendicular grooves 18, 19 (fig. 4.7), width Bi of hem 21 and carrier bar 20 3 {figure 7) corresponds to the width B of the grooves 18, 19 10 (Fig.4.5) of the rod 5 of the tongue needle 1 (Fig. 1), the thickness h2 (Fig.8) of the carrier is equal to the depth hi of the grooves 18.19 (; Fig.4.5), and the tip thickness ha (Fig. 8) is less than the depth h / i of the groove 12 (Fig. 6). The width hs (Fig. 2) of the asymmetrical groove 4 of the 15 needles of the bed is equal to the thickness Bz (Fig. 5) of the rod 5 of the tongue needle 1 (Fig. 1). Cutout 26 is made for relief (Fig. 1.4).

To prepare for operation, the needle 1 (Fig. 1) is connected to the carrier 3. (Fig. 7) by installing an inclined section 25 (Fig. 8) of the carrier 3 into the notch 16 (Fig. 1) 20, which is inclined to The side surface 17 (FIG. 3), then the pc 21 and the carrier rod 20 3 (FIG. 7) are installed in mutually perpendicular grooves 18.19 (FIG. 4), and the tip 23 (FIG. 8) is installed in the groove 12 (fig.Z).

Next, the needle containing the tongue needle 1 itself, connected to the removable 30 carrier 3, is placed in the asymmetrical groove 4 (Fig. 2) of the needle bed, the width of which hs corresponds to the thickness B2 of the needle 1 (Fig. 1.5).

A needle needle 9 (Fig. 1) is installed in a 35 inth wedge channel (not shown) and moves in a circumferential and longitudinal (along a groove) direction, providing known operations in the underside and transfer of loops. During the transfer of the loops, the needle transferring the loop 40 rises above the baffle line of the needle bar to a height 1.5 times greater than npVi in conventional knowledge. This causes the previously connected loop to fall well below the end of the open tongue 2 and the loop extension 45 by the inclined part 24 of the carrier 3, which ends with the abutment of the loop in the ledge 8 of the wide part of the rod. After that, the needle, which passes the loop, stands, and the needle, which was previously set at the level of the 50 line of the needle bed, is advanced so that

its hook is extended beyond the loop section on the ledge 8, the entrance between the needle shaft 5 and the carrier 3. Having reached this level, the receiving needle stands, and the needle passing the loop lowers, leaving the loop under the receiving needle hook 23, and the tip 23 of the carrier 3 of the transfer needle bends back, output from the side groove 12, and passes the thickness of the receiving needle. After this, the carrier, due to elasticity, returns the tip 23 to the side groove 12 for stringing on its inclined loop section 24 in the next loop transfer cycle.

A technical advantage in industrial use is higher reliability when transferring loops due to increased needle stiffness and reduced deformation during this work, as well as providing higher accuracy of the connection between the needle and the carrier, which eliminates carrier displacement and the associated defect during transfer. loops.
