Device for adjusting the course density at

a circular knitting machine

The invention relates to a device for adjusting the course density in a circular knitting machine, which is provided with one or more knitting systems, at least one of these knitting systems, for knitting wedge-shaped knitted parts, for Example heels and toes of stockings by commuting of the Hadelzylinders is formed.

Previously known devices for changing the Meshes on circular knitting machines consist of Lock parts which are arranged on a lock casing in such a way that, for example, those in the main knitting system for round and pendulum knitting arranged gate lock parts are coupled together, so that when Adjustment of the cam lock parts which are effective during circular knitting and also those during pendulum knitting

G09333 / Q909

effective cam lock parts are set.

The disadvantage of this device is above all; in that due to inaccuracies in production and various conditions of thread insertion in the Madelhaken in circular and pendulum knitting in the main knitting system as well as different Conditions for thread chopping with the help of sinkers it in pendulum-knitted wedge-shaped knitwear Part of the formation of stripes occurs, which 'due to uneven mesh length in the individual rows of stitches is caused.

The invention eliminates the stated disadvantage.

The invention consists in that cam lock parts, which in a knitting system that is active in both circular and pendulum knitting of the needle cylinder Determine the feed depth of the needles, regardless of the height. depending on each other, for example by means of regulating screws, can be adjusted into a basic position and in the course of knitting with the help of a common actuating mechanism, for example a goods sealing ring controlled by means of operating levers.

The device according to the invention is both in the It works reliably as well as in operation and enables a reduction if the setting is correct the formation of stripes in the pendulum-knotted wedge-shaped Greetry part, for example in the stocking heel,

The essence of the invention is based on the following Description of an embodiment example shown schematically in the drawing explained in more detail. Show it:

1 shows a schematic partial view in view P of the arrow drawn in FIG. 3 on the development of lock parts in the main chain system of a double-cylinder circular knitting machine, which is in operation both during the circular and pendulum motion of the needle cylinder;

Fig. 2 is a partial view of the outside of a Lock jacket with the lock parts of the same main knitting system already shown in FIG. 1 and the device according to the invention;

Fig. 3 is a plan view of part of the main stream system and to the device according to the invention according to levels III-III in Pig. 1.

As can be seen from FIGS. 1 and 2, the Madel cylinder, not shown, moves in the direction of S _{1 of} the arrow during circular knitting Pendulum motion of the Madel cylinder in the direction S _{1 of} the arrow, it also moves in the direction S «of the arrow.

The main knitting system in which the threads both in circular knitting as well as in the pendulum motion of the needle

- 4 -909838/0909

Cylinder are actuated, ordered from a vertically movable cam lock part 1, to which a likewise vertically movable lower lifting lock part 2 is assigned. These lock parts 1,2 are in action in circular knitting. During the pendulum motion of the needle cylinder, a heel cam lock part 3 and a lower lifting lock part 4 assigned to it are assigned. These two lock parts can be moved vertically. The cam lock part 1 moves vertically in a recess 5a of an inclusion lock part 5 and the fc heel lock part 3 moves in a recess 6a of an inclusion lock part 6 which, like the inclusion lock part 5, is stationary. Between the two inclusion ^{lock parts 5, 6, a} central countersunk lock part 7 is fixedly arranged, which determines the insertion position. A central lifting lock part 8 is fixedly arranged between the two lower lifting lock parts 2, 4.

A holder 9 (FIG. 2) of the heel cam lock part 3 and lower lifting lock part 4 and a holder 10 of the Link lock part 1 and lower lifting lock part 2 are vertically movable in a fixed lock casing

11 stored, around the outside of a goods tight ring

12 is rotatably arranged. At the scope of this product sealing ring 12 cutouts 1.2a, 12b, 12c are provided. One arm end of one engages in the cutout 12a angular! operating lever 13, which is on a in the lock jacket 11 screwed pin 14 is pivotably mounted. The other end of the arm of this operating lever 13 is provided with a regulating screw 15, which is against a projection 10a of the holder 10

- 5-909 838/0909

supported, the set position of this regulating screw 15 is secured with the aid of a screw nut 16. In the cutout 12b of the goods sealing ring 12 engages an arm end of an angled actuating lever 17, which is on one in the lock jacket 11 screwed-in pin 18 is pivotably mounted. The other end of the arm of this operating lever 17 is provided with a regulating screw 19, which is supported against a projection 9a of the holder 9, the set position of this regulating screw 19 is secured with the aid of a screw nut 20. In the cutout 12c of the Y / arendichteringes 12 engages an arm end of an angled main operating lever 21, which is pivotably mounted on a pin 22 screwed into the lock casing 11. That the other end of the arm of this main operating lever 21 is, for example, from a main switching drum, not shown the knitting machine controlled by the intermediary of a lever mechanism, also not shown.

The device works as follows:

Adjusting the lock parts 1,2,3,4 in a vertical position Direction into a basic position takes place by turning of the regulating screws 15,19, which are against the Support projections 9a, 10a of the holder 9,10 of the aforementioned lock parts 1,2,3,4, their basic position with Is secured with the help of the screw nuts 16, 20. This setting enables generation inaccuracies to be eliminated in the production of individual parts.

The regulation or change of the stitching in the individual rows of stitches in the course of the waistband and also. Pendulum knitting is usually carried out by the pulse of the main indexing drum of the knitting machine, for example with the interposition of a lever mechanism which controls the main operating lever 21. Ring 12 engaging the lever arm this ring in the direction of arrow S ^*: by pivoting said lever 21 about the pin 22 into the cutout 12c of the Warendichte- twisted (Mg. 2). As a result of this leilum- 'rotation of the ring 12, the cutouts 12a, 12b begin to take along the engaging arm ends of the actuating lever 13 * 17 also in the same direction S *. By pivoting both levers 13, 17 around the pin

14.18 the associated regulating screws are also used

15.19 taken, which on the projections 9a, 10a the lock part holder 9 »10 press and this with the. Move locking points 1, 2, 3 »4 in the downward direction. As a result of this fact, the working feet passing through between these cam parts are activated by actuating means, for example sinkers in circular knitting the ball cam lock part 1 and the pendulum action of the needle cylinder lowered more by the heel lock part 3, whereby the individual stitches in the associated. Row of stitches are lengthened compared to the previous row of stitches and thus also the density ~ ζa course is changed.

By releasing the main operating lever 21 reverses the goods sealing ring 12 against the direction S, des Arrow back to the original position .. This also releases the operating levers 13 ^ 17,

which also assume their original position. With them, the associated lock part holder 9,1.0 of the lock parts 1,2,3,4 also take their original position Position.
