The document EP 2 604 359 A1 relates to a latch needle with a needle body with a shaft in which a slot delimited by two side walls is formed. In order to create an improved tongue position, we in the document EP 2 604 359 A1 proposed forming in the slit walls two continuous bearing openings which are aligned with one another and have a matching constant cross section, with a latch which has a latch shaft with a continuous latch hole whose cross section is smaller than the cross section of the bearing openings, with a bearing pin which extends through the latch hole and having bearing heads of the same shape that are produced within both bearing openings by plastic deformation.

The document EP 1 911 867 A1 relates to a needle bed of a knitting machine, with a base body which is provided with a number of guide channels which are designed for receiving and longitudinally displaceable mounting of knitting tools between two guide webs.

The document DE 433 757 C relates to a braking device for needles on knitting machines. the document DE 433 757 C according to which brake springs are placed around shafts of needle jacks. The springs are segmented or angled, provided with slits and with these slits enclose the shafts of the rams, so that the rams are braked during a gear and in every position and thus also for the needles. It is proposed to provide the springs with slits at their ends and optionally also at their apex with a slit or incision. A jack is braked by an inserted brake spring when, for example, its apex comes into contact with the next needle shank. If the brake spring is also provided with a slit or incision at the apex, into which the next pusher is inserted, the pusher is guided by the spring at two points and the adjacent pusher at one point.

Braking sections of the braking elements 704, 706 are prestressed against the knitting elements 714 and form friction pairings with the knitting elements 714. Braking forces are thus applied to the knitting elements 714 . Braking elements 704, 706 each cause a predetermined, defined braking force and/or a predetermined, defined braking force profile over a movement path of knitting elements 714.

The braking elements 704, 706 can be exchanged for other braking elements in order to change or restore a predetermined defined braking force and/or a predetermined defined braking force profile over a movement path of the knitting elements 714. The knitting device 700 with the knitting element carrier 702, the braking elements 704, 706 and the knitting elements 714 forms a modular system.
