BACKGROUND OF THE INVENTION

Small diameter knitting machines for the manufacture of sock goods are known in which the wedge heel or toe is formed in a return knitting system. The stitching is handled by the ejectors that move the needles to the non-working instep position, which is higher than the needles closing position. When needles are added, the picked needles are then returned to the knitting path by means of a puller. Heel thus knitted has a very good quality, especially in the area of the run. The disadvantage of this solution is that the device is space-intensive, which prevents multiple knitting systems from being arranged around the needle cylinder.

Further, small diameter knitting machines are known in which the return heel knitting system is not equipped with a puller and ejector, but the picking and adding of the needles takes place from the selection patterning device. In this type of knitting, the instep needles are moved in the lower non-working position and the removed needles pass through the nipples. below the retractable locks in both directions of rotation ^J in the needle cylinder. As a result, the stitched eyelets are constantly tensioned and loosened, and the stitches become excessively stressed and damaged: To overcome this problem, the machine knits the heel so that 5 on the needle, adjacent to the needle knitting the last stitch of one heel and then the first a loop of the next heel row,; se'uplet like a catch. This solution ensures close ujímek,, * · ψ '1 · _r' specific binding freedom to compensate for the unwanted voltage and thus does not damage the last rows of stitches stalemate. These catch eyelets are confused both when taking and adding, ie in all rows of wedge heels. Although this solution eliminates excessive stress on the scratches, it is nevertheless an interference with the weave structure in close proximity to the scratches, which in a way damages their appearance. This device also requires additional patterning devices.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome these drawbacks.

The function of the above locking system is as follows. First, it is explained for better understanding in rotary knitting of six systems and in transition to return knitting. When knitting six systems in the SI direction, the radial slide buttons 13 to 18 are turned off and the radial slide buttons 25 to 30 are turned on. Updators 67 to 72 are operable to control the patterning tracks 88 according to the program. 55 to 60, which lift the needles to the closing positions at the closing level 94 by means of the sliding trackers 89 and the needle trackers 84. Here, the yarn is loaded into the needles 83. Thereafter, the lower nodes 86 of the needle tracks 84 are depressed by buttons 25 to 30, thereby squeezing their opposed nodes 85. Beyond the nodes 85, the needles 83 are retracted to the retracting level 91 along the right edges of the retracting cams 7 to 12 and the needles 83, , eyelets are formed. Meanwhile, the pulling locks 43 to 48 have pulled the sliding tines 89 and with them the rocking tines 87 back to their original level, their nodes being pushed back by the fixed buttons 31 to 36.

At the start of heel knitting, the update command 67.68.69.71 and 72 is commanded to stop the selection to the respective knitting systems. The respective non-selected needles 83 then, after being lifted by the lock segments 37, 38, 39, 41 and 42, then move beyond the working level 92, where its nodes 85 are crimped by the fixed buttons 19, 20, 21, 22, 23 and 24, and further influenced by retractable locks. The last stitches of the rows are then secured in a known manner by the catch eyelets, using the catch locks 49,50,51.

_53 a_54.

Next, knitting is continued only with a retractable lock 9 and an update 70. The control electronic device turns on the radial sliding buttons 13.14.15.17 and 18 and further turns off the radial sliding buttons 25.26.27.29 and 30: Button 16 remains off and button 28 is on. Thus, the lock system is ready for return knitting. The retractable lock? the needles 83 are raised from the retracting level 91 to the non-working level 92 by means of the butts 85, and since the update 69 does not work, their butts 85 are pushed by the fixed button 21 and the needles 83 extend horizontally further.

The function of the updater 70 is now terminated and the selector is activated with the update 69 for the first heel row of the first wedge heel received. The selected swinging sheaves 87 are raised by the right-hand lifting edge of the closure lock 57 and the corresponding needles 83 are lifted to the closure level 94 by means of the sliding shutter 89, their nipples 85 pressed into grooves 82 of the needle cylinder 81. Once all the needles 83 of the first heel arc have been raised, the needle cylinder 81 begins to rotate in the direction S2. The heels 85 of the needles 83 of the first heel arc pass through the retract lock 9 and are then squeezed back by the pushbutton 28 into the working position and retracted by the left edge of the retract lock 10, the yarns being loaded into the respective needles 83. Next, an update 70 is actuated which raises the closing lock 59 to the closing level by means of the tracks 87.88.89 and 84 and the left lifting edges. Similar to the embodiment of the SI needle of the second heel arch. The instep needles 83. again as in the previous case, still passes at the non-working level 92, which is higher than the depth of needle retraction 83, but lower than the gripping position at level 93, in order not to participate in knitting. At the closing level 94, the needles 85 of the needles 83 are pressed again by the button 17 and then undergoes retracting locks, the entire heel arch being arranged in the closing position on the other side of the return knitting system. Then, the needle cylinder 81 begins to rotate toward S1 and the entire cycle is repeated.

The cycle described above is used in stitching stitches, with the last stitch stitch stitches being secured by the following procedure. The last heel arch needles 83 are not retracted and lifted to the closing position when retracted, but are passed out of working position with the eyelet 01.02.03,04 (Fig. 2) at level 92 along with the instep needles. The closure lock 58 is lowered to the catch level during heel knitting, as shown in FIG. Thus, when the rotation directions are reversed, the non-lifted heel eyelets 83 come back into the knitting system in the off-and-off position, the tip of the retracting cams 9 and W, respectively. Further, by means of the updates 69, the rocker stops 89 and 84 and the lifting edges of the closing lock 58, they are raised to the catch level 93, i.e. to the catch position along the path t. Then their nodes 86 are pressed by the button 29 and their nodes 85 are squeezed, and the respective needles are retracted at the retract locks 9 and 10 respectively. Further, by means of the updates 69, the rocker tracks 87, the track shoes 89 and 84 and the lifting edges of the closing lock 58 are raised to the catch level 93, i.e. to the catch position along the track t. Then, their nodes 86 are pressed by the button 29 and their nodes 85 are squeezed, and the respective needles are retracted at the retract locks 9 and 9, respectively. 10.

These needles 83, raised to the catch level, but as the needle cylinder 81 is rotated, re-engage in its hooks next to the removed eye 01.02.03.04 its return platinum loop R, which surrounds the needle hook when returning the needle cylinder from dead center. This is also made possible by the fact that the lifting of the needles 83 takes place in the area of the open disc sinkers 97 running along the track 96. Since the stitches 01 to 04 have only one regurgical platinum cage and on the other hand the yarn goes into the guide. they do not fall on the needle scape and the second platinum cup is captured as described above. In the further course, the needle passes along with the instep.

This method repeats itself during the seizure or formation of the first heel wedge. When knitting the second half of the heel, the loop-catching procedure R is not repeated and the two parts are woven together in a conventional manner.
