Device for more perfect knocking off in rows of stitches by means of sinkers on a double cylinder

Circular knitting machine

The invention relates to a device for achieving a more perfect cast-off in courses by means of knock-off plates on a double-cylinder circular forming machine, in which the individual stitches are formed with the help of girls, polygamy in the formation of stitches with straight cut-off and sickle-shaped containment plates work together, with the needles and also the inclusion plates when the needle cylinder is rotated, they are actuated by the knitting machine's lock systems.

Previously known devices of this type are constructed in such a way that the sinker loop handles in the with With the help of effective needles of the lower needle cylinder rows of stitches formed by warping individual handles

over the bridges of crescent-shaped containment plates and the already mentioned sinker loops in the with the help of effective girls of the upper ¥ nobility cylinder formed rows of stitches are formed by warping the handles over the edges of straight sinkers, The enclosing sinkers move in a radial direction move, the individual stitches formed on these sinkers are knocked off properly. But since the upper straight sinkers in radial Do not move sighting, the knockdown of all stitches is significantly deteriorated and when knitting ^ of links-linkware the stitches are at some points- ™ len not beaten at all. The discount will then be replaced by an increased deduction effect, which however not enough in such circular knitting machines Let can be developed, in which the individual knitted fabrics with each other, for example by the known ! Crennlinie, are not connected, but each one Empty knitted fabric! Blame begins. With backpack iht the fact that the individual stitches are not properly knocked off by the enclosing sinkers, piercing occurs especially with sample machines or impaling previously formed stitches on the needle hook, thereby reducing the quality of the knitted fabric | will. This deficiency is most evident at the beginning of knitting a stocking foot sole with a needle needle division 1: 1 noticeable.

The invention avoids these disadvantages. The invention The object is to improve the device in the simplest possible way to the effect that it works reliably and also enables

that the inclusion sinkers both in the meshes of the needles effective in the lower cylinder cylinder, as well Form sinker loops in the stitches of the needles that work in the upper needle cylinder.

The invention "is that the axial movement of the Needles in the upper, and also in the lower needle cylinder in the Course of the job change from a laying to a Kulierbahn is interrupted until a yarn is trapped between the hooks of the needles and tabs of the containment sinkers. It is useful to if a lock system of the upper and lower needle cylinder is equipped with ball cam lock parts, which working feet of needle slides and thus also needles assigned to them by the action of Kulierkanten actuate, these Kulierkanten are arranged perpendicular to each other and in different from each other Direction and are interrupted by horizontal edges, behind which in the direction of rotation Needle cylinder gate edges, for example vertically movable gate lock parts, advance further.

It is advantageous if the horizontal edges of the cam lock parts are arranged at one point which hook of the needles from the upper and also lower needle cylinder a knock-off plane of enclosing sinkers happen.

It is also advantageous if the containment plates with their jiases at the point of interruption of the axial movement the needles assume an enclosed position.

A double cylinder fiund knitting machine consists of a known rotatable lower and upper needle cylinder around which stationary lock shells are arranged, whose part is shown in Fig. 1 in the developed state. The lock shell part shown as an example belongs to a known and not shown main knitting system in which the upper lock shell consists of a fixed lock ring 1 and a fixed lock part 2, between which the Track for guiding working feet A of the needle slide is formed. The mentioned track is made of a single

final web a, a run-up edge 3, laying web b and Kulierbahn formed. The latter is through a gate 4 and a horizontal edge 5 determines which corresponds to a path c, this path c being the coulier edge divides into two parts. The path c connects to a vertically movable upper cam lock part 6, along whose coulier edge 7 then advances the coulier path up to a horizontal coulier plane d. The Kulierstellung continues until an edge 8 of the lock ring 1 again the working feet A and thus the ladein begins to lift, which with its actuation means the upper lock system in the direction of the arrow S run through.

The lower lock jacket consists essentially of a stationary lock ring 9 »which has one edge the path for guiding work feet B of the liadelplatinen certain The work feet B mentioned are in the Main knitting system guided in an inclusion path a ', which is determined by the fixed lock ring 9 and the fixed part of a heel cam lock part 10 is and extends to an edge 12 of a central countersunk lock part 11, along which edge 12 the Working feet B are guided into a laying track b '. The laying web b * is in the direction of the arrow S by a Kulierkante 14 terminated, which is formed on the stationary part of a cam lock part 13. Perpendicular under the horizontal edge 5 arranged in the upper lock jacket is also the one in the lower lock jacket arranged Kulierbahn interrupted the working feet B, which move in a horizontal path c ', which from above by an edge 15 of the stationary

Kulierschloßteiles 13 is determined. This orbit c ' is vertically movable in the direction of arrow S by a cam edge 17 in the stationary cam lock part 13 lower gate lock part 16 ended. The lower end of the Kulierkante 17 connects to a horizontal Kulierbahn d ', which terminates by a discharge edge 18 of the stationary lock ring is.

Double needles equipped with hooks 20 (] Pig. 3) 19 are displaceable in longitudinal grooves formed by ribs 21 of an upper rotatable needle cylinder 22 stored, wherein in the lower rope of the upper cylinder 22 a support sleeve 23 is mounted and its lower edge is provided with fixed straight sinkers 24. With the help of needles 19 of the upper needle cylinder 22 known sinker loop handles are formed on the knockdown edges 25 of these sinkers 24. JThe sinkers 24 are in the Eragbüchse 23 rotating with the upper needle cylinder 22 by a pressure plate 26 recorded.

Double latch needles 27 equipped with hooks 28 are also displaceable in longitudinal grooves formed by ribs 29 of a lower rotatable HadelZylinders 30 stored, being in the upper part of the lower needle cylinder s a rotatable sinker guide ring 31 is seated, in the hats of which crescent-shaped containment sinkers 32 are mounted radially displaceable. The latter have working feet 33 and sinker noses 34, under which an edge 34a the so-called inclusion or tee

level forms. The working feet 33 are guided in a track C (Pig.2), which with the help of two stationary, in the interior of the plate guide ring 31 overlying Sink lock rings 35,35 'is formed (Pig. 3). The sinker ring 31 with the superimposed Lock rings 35,35 * is supported by a rotating ring 36 and whose locking nut ring, not shown, is held on a sleeve, also not shown, which is inside the lower thread cylinder 30.

The path C (Figure 2) of the working feet 33 in the direction of the arrow S is given by various edges 37, 38, 39 and intermediate transitions 37a, 37b, the edge 38 of the upper sinker lock ring 35 an open position, the edge 37 a closed position and the edge 39 a cut-off position of the cooperating with her Enclosure sinkers 32 are determined.

The device works as follows:

The upper and also lower Madel cylinders 22, 30 revolve in the direction of the arrow S. In this direction, both the working legs A, B of the needles 19,27 be controlled needle slide, and the working legs 33 of input \ closing boards 32 in the path of the two sinker 0

and stationary lock part 2 located containment spell a, from which they pass through the run-up edge 3 of the ortsfe-. most Schloßteileee 2 are raised in the laying track b. At the same time, the working feet B also run through Hadelschieber and thus also the associated ladein 27 of the lower needle cylinder 30 that is located between the stationary lock ring 9 and the lower cylinder lock part 10 Inclusion path a ', from which it passes through the trailing edge 12 of the central countersunk lock part 11 in the Laying lane b 'are pulled down. In the laying lanes b, b ' are in the hooks 20,28 of the rebukes 19,27 through the mediation of a thread guide, not shown, yarn inserted. When the working feet A run into the needle slide on the Kulierkante 4 of the fixed lock ring 1 and the working feet B of the needle slide on the cam edge 14 of the stationary cam lock part 13 are the HadeIn assigned to the needle slides pulled down or lowered into the ICulation position. At that point at which the containment sinkers 32 from the edge 38 of the upper sinker lock ring 35 certain open position in the determined by the edge 37 of the upper sinker lock ring 35 containment position should pass, take the needles 19 of the upper needle cylinder 22 as well as the Hadein 27 of the lower Needle cylinder 30 is in such a position that its hooks 20,28 pass the cut-off or containment plane, which is formed by the containment edge 34a located under the rabbits 34 of the containment plates 32. At this moment the axial movement of the needles 19,27 is interrupted because the working feet A of the Needle slide and associated MadeIn 19 in the horizontal Move track c and the working feet B of the needle slide and associated girls 27 in the horizontal track c *. That held by the hooks 20, 28 of the needles 19, 27

tene yarn 40 is still through at this moment the noses 34 of the enclosing sinkers 32 enclosed because their working feet 32 through the transition edge 37a of the upper sinker lock ring 35 were moved from the open position to the locked position, which is determined by the edge 37 of the same sinker lock ring 35. After enclosing the yarn 40 between the hooks 20,28 of the Badein 19 »27 and noses 34 of the enclosing plates 32 run the working feet A of the needle slide in the upper needle cylinder 22 on the coulier edge 7 of the vertically movable upper cam lock part 6 and the working feet B of the needle slide in lower needle cylinder 30 on the cam edge 17 of the vertically movable lower cam lock part 16 As a result of the progressive movement of the working feet A, B in the direction of arrow S, they take them in the Kulierbahn d, d 'a coulier position, whereby the associated needles 19 »27 of the upper and lower needle cylinders 22.30 are in a Kulierstellung. The size of the kulation depth and thus also the row density of the knitted fabric is regulated by adjusting the height of the vertically movable gate lock parts 6, 16.

After the yarn 40 is trapped between the hooks 20, 28 of the needles 19, 27 and lugs 34 of the containment sinkers 32 is, the sinker loops of the individual tabs from the yarn 40 are also in the through Needles 19 of the upper needle cylinder 22, stitches formed on the lugs 34 of the containment sinkers 32, whereby after the completion of individual stitches in a row of stitches, a complete knockdown of this newly formed Mesh is secured.
