Abstract

The present invention relates to a control device for sinkers in a circular knitting machine to manufacture socks with double border. The operational border range of the cam ring that controls sinkers is wider than the remaining portion and therefore sinkers extend with their points up to the stems of the needles, thus preventing wire rings to slide from said sinkers.

Description

The invention relates to a circular hosiery knitting machine with an apparatus provided with instrument hook-on sinkers for hanging loops, for example when knitting a double hem in cooperation with needles.

Known small diameter knitting machines with double hem knitting machines are equipped with needles whose tongues are not shorter than 7 mm. With these machines, there is no difficulty in forming a double hem. For machines equipped with needles whose tongues are 5 mm or less in length, it is necessary at the beginning of the entanglement that the instrument sinkers were as low as possible above the discard sinkers due to the reliable introduction of threads into the needles. In this case, however, already in the following knitting system, i.e. after hanging the loops, where the loop is not yet formed, the hanged loops are withdrawn by the needles going from the closing to the retracted position.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-mentioned disadvantage, which is essentially achieved by the fact that on the arc between the knitting system where the hooks on the sinkers are hung and the point of retraction.

The advantage of the solution is that by simply adjusting the lock rings on the device, the secure holding of the hanging handles is solved.

1 shows schematically the arrangement of the locking means of the apparatus, FIG. 2 schematically illustrates the position of needles, sinkers and overhangs as seen from the side in a knitting system following the knitting system, where Fig. 3 is the same as Fig. 2, but seen from above, Fig. 4 is the same as Fig. 3, but in the knitting system in the second order after hanging, Fig. 5 schematically shows the position of the needle, the sinker and the sinker. retracting the eyelet.

A known one-cylinder circular knitting machine for manufacturing hosiery is provided with a needle cylinder (FIG. 5), in which longitudinal grooves are stored needles 2 which during knitting cooperate odhazovými sinkers 2 · ^{Above the} needle cylinder 1 there is a unit 4 ^, in which instrument sinkers 5 for carrying loops when knitting a double hem or knitting the unparalleled rows of closed spokes. The instrument sinkers 5 are actuated by a lock ring 6 (FIG. 1) and further by two switchable axially displaceable locks 7 and 8 '. The lock 7 serves to slide the sinkers 5 into the working position and the lock for their insertion. The locking ring 6 is formed in such a way that its working edge between the knitting systems and the knitting system 6, respectively. The corresponding heights of the knitting systems P1 - P4 are round with radii R1 and R2, where R2> R1. The radius R2 is formed on the arc behind the knitting system P1, where the handles are carried to point A, where the working edge of the lock ring further moves away from the center of the apparatus 4 to release the handles when the stitches are retracted. The instrument sinkers 5 are extended at the radius R2 so that their tips intersect the vertical lines 21 interspersed with the groove bottoms 2.

The function of the device described above when knitting a double hem is as follows. Lock 2 ^e j lowered into working position and ejects the instrument of platinum to the working position. Lock 2 is off. The knees 51 of the sinkers 2 are brought to the working edge of the lock ring 15. As a consequence, the knitting system Pl known manner к К transferring the loops (Fig. 2, 3) of knitting platinum on the instrument 2 ^{and the} distribution of the needles 2 in a ratio of 1: 3. With further rotation in the direction of arrow S, the knees 51 of the sinkers 2 are retracted only to the radius R2, so that the tips of the sinkers 2 with the hinged keys К reach into the space behind the arc formed by the groove bottoms. position. In the knitting system P2, the needles 2 are in the 1: 1 distribution and are raised to the closing position as shown in FIG. 2. The extended tips of the sinkers 5 do not allow the knobs К to slip outside the sinkers 2 or. . at line 21 and therefore of the needle stems 2 ^and 3 ^and thus ensure their possession. In other knitting systems РЗ ^and P4, the sinkers 2 ^{on the} radius R1 are pulled more, as seen in their position relative to the needles 2 in Fig. 4. Here, the handles К can no longer be removed from the sinkers 2, since more rows are already created knitwear.
