Disengaging the needle foot 1 ··; is effected by means of the plate 15 ″, which is articulated at its front end with a slide 19 which is provided at its front end with a sloping surface 20 which can run onto a counter sloping surface of a bar 21 at the same level, which extends above the needle shafts 15 over the entire length of the needle bed 10 provided with needle channels. When the slide 19 hits the bar 21, the loading shaft 13 is locked in its bent position of a control foot 22 of the plate 15, which is described in more detail below. The return of the plate 15 to the rest position shown in Fig. ^{5 1 Ig.}

The control foot 22 of the board 15 is formed in one piece with a slide 23 which is the same thickness as the board 15 has and is mounted in a longitudinal groove 152 of the board 15 so as to be longitudinally displaceable. It protrudes the control foot 22 through an upper opening through a front stop edge 153 and a rear stop edge 154 for the control foot 22 is marked, the plate 15. Between the two Ansohlagkanten 153 and 154, the control foot 22 in the plate 15 can be moved freely in the longitudinal direction.

and padlock of the flat knitting machine, with which control of the needles is effected. The rope lock is essentially through the lock parts 26,27,28 and 29 formed. The lock channel is designated with the reference number 30 ". The cape chi ο ß is limited by lock parts 31, 32, 33, 34 and 35 ". The depressions 291 and 331 in the lock parts 29 and 33 can be used to correct the position of the needle feet 14 disengaged! censures 12 serve. The lock also has several reset lock parts 36,37,38,39,40 and 41, which act on the return feet 151 of the sinkers 15. The lock parts 36 and 38 are against Spring force in the lock bed can be lowered, since they should only be effective in one flow direction. That Sinking takes place automatically by the resetting feet 151 of the plates 15 running onto the lock part bevels 361 and 381. In.Pig.3 is also the control lock track 42 for the control foot 22 of the plates 15 is shown.

The control lock track 42 has multiple branches provided, "in which by lever lock parts 43 the Control lock track each in a through branch 421 and is divided into a propulsion branch 422. At the beginning and at the end of each branch is the control lock path 42 at least on the side of the pass-through branch 421 limited by permanent magnets 44, each of which is narrow and excitable according to the pattern in the direction of passage Control magnets 45 are connected upstream. The permanent magnets 44 strive to the control feet 22 of the boards
