The invention relates to a flat edge knitting machine System Cotton with thread control elements, the in a bar above the machine needles that can be moved along the machine needles by means of an eccentric drive are arranged. To keep the old stitches and the newly cultivated thread loops separate grip the thread control elements with their downwardly bent tips into the usual, the hook receiving Zasche the machine needles.

Devices of this type are already known from French patent specification 1215 078, wherein the thread control elements arranged at the level of the machine needles and provided with a stop are. The machine needles and the thread control elements can only be moved in the horizontal direction. The stops on the machine needles have the task of placing the newly cultivated thread loops under the To bring hooks of the machine needles to be lead in the pressing position.

It is the object of the invention to provide improved thread control elements.

According to the invention this object is achieved in that the stitching of the machine needles in their Basic have an opening into which the bent tips of the thread control elements through a eccentric, longitudinally displaceable cams can be swiveled in. The cam works with a roller lever together, which is attached to the bar which is pivotably mounted on the arm of the machine needle bar the thread controls is attached.

These measures ensure safe and non-destructive cooperation between the machine needles and ensures the thread control elements and avoids deformation of the bent tips of the thread control elements; because in practical use leads to the pressing of the curved tips of the known thread control elements after a certain period of time to deformation in the teeth provided for this purpose on the machine needles the thread control elements, so that they no longer perform their task without interference and are therefore renewed Need to become. With particular advantage are between the bar of the thread control elements and the Machine needle bar setscrews provided.

The invention is illustrated in the drawings. It shows

Machine needle bar 2 are attached, shown. The machine needle bar 2 is on the arm 3, a Roller lever 4 and a roller 5 operated. It is the usual machine needle bar eccentric 6 on the Main eccentric shaft 7 is provided. Furthermore, the usual sinkers 8, sinker head piece 9 and others conventional bars or rails 10 and 11 are shown.

There are thread control elements 13, which are held in bars 12, are provided. The bar 12 is inclined, the thread control elements 13 have similarly inclined downward shafts, horizontal shaft parts 13 a and tips 13 b bent downwards from the free end of the shaft part so that they are perpendicular to openings 14 (Fig. 2, 4 , 5) are aligned, which are formed in the base 15 of the prongs 16 receiving the hooks of the machine needles 1 in the shafts of the machine needles 1.

The bar 12 (FIG. 1) is rotatably connected to the arm 3 by arms 12 ″. Adjusting screws 17, the the arm 3 are attached, grasp behind the machine needle bar 2, around the needles relative to the pressing edge 28 to be able to adjust. Furthermore, an eccentric adjustment device is at the pivot point of each Arm 12 ″ provided to the thread control elements 13 and the machine needles 1 horizontally to each other to adjust.

The bar 12 is also carried by roller levers 18 which rest against cams 19 by springs 18 a , which stepped cam parts 19 ″, 19 b, 19 c,

19 d have and are slidably displaced in order to hold the various cam surfaces alternately ready for the roller lever 18. For this purpose, the cam 19 is arranged to slide horizontally in a guide rail 20 which is attached to the board head piece 9 and carries an arm 21 to which a lever 22 is rotatably attached and at its upper end by a pin and slot connection 23 to the cam 19 and is connected at its lower end to a rod 24 of an eccentric-operated device which is mounted on the rails 10, 11 and has a roller lever 25 with a roller 25 λ which is operated by an eccentric 26 on the main eccentric shaft 7. The machine needles 1 and the chair needles 27 (FIGS. 2 and 8) are operated in the usual manner for knitting, the drawing process in FIG. 2 is shown. It is also shown that at this point in time the parts 13 a and the bent tips 13 b of the thread control elements 13 lie between the sinkers 8 and the machine needles 1, the roller lever 25 being arranged on the part 19 c of the cam 19. The chair needles 27 are lowered in order to pull new stitches along the noses Sa of the sinkers 8 during their return movement (FIG. 3). During this time, the machine needles 1 lower themselves to a level for pressing their hooks through a pressing edge 28, so that the tips 13 a of the thread control elements 13 are at a distance above the machine needles 1. At this point in time the machine needles 1 advance a little and take the thread control elements 13 with them, so that the machine needle hooks release the old stitchesMOL and the tips 136 lie below the old stitchesMOL, as shown, with the roller lever 25 on part 19c of the cam 19 lies. In the next stage according to FIG. 4, the machine needles 1 and the thread control elements 13 advance onto the pressing edge 28, and the sinkers 8 retract further, so that new chair needle loops FNL are drawn from the chair needles 27 through their old stitches FOL and new machine needle loops MNL are drawn over the thread control elements 13. In addition, the roller lever 25 rests on the part 19 d of the cam 19 so that the thread control elements 13 are lowered until their tips 13 b protrude through the openings 14 in the machine needles 1 in front of the old stitches MOL. During this time, the chair needles 27 perform an inward movement. You carry the stitches with you until the new machine needle stitches MNL are under the machine needle hooks (Fig. 5); the old machine needle loops MOL are held away from the machine needle hooks by the tips 13b. If consequently the machine needles! (Fig. 5) press their hooks against the pressing edge 28, the old MaschenMOL are held safely away from the new MaschenMiVL by the thread control elements 13. In this position, the roller lever 18 remains on part d of the cam 19. FIG. 6 shows the next stage, in which the roller lever 18 lies again on the part 19c of the cam 19, so that the thread control elements 13 are raised so that their tips 13b are released from the machine needles 1. The machine needles 1 go back to place the old ίο stitches MOL on the hooks while the hooks are still pressed. The machine needles 1 then knock off the old stitches by giving them back further, and the various organs return to the position shown in FIG. 1 back to repeat the work cycles. The parts 19 a, 19 b of the cam 19 are properly shaped according to FIG. 7 and 8 used. F i g. 7 shows that the thread control elements 13 are lifted by the roller lever 25, which lies on the part 19b, so that machine needle loops get under the tips 13b when the chair needles return to the reduced position in which they are connected to the deckers 29 assigned to the chair needles cursing. Fig. 8 shows that the thread control elements 13 are raised by the roller lever 25 therhin. This works on the part 19 a, so that the tips b of the thread control elements 13 are released from the cover 30 associated with the machine needles during their movements. Patent claims: 1.
