Flat knitting machine having needle selector device

Flat knitting machine with at least one needle bed (25) with needles (42) which can be moved longitudinally in slots (40) of needle bed (25) and with at least one set of cams (10-20, 23-39) movable relative to needle bed (25), with cam parts (10-20) for the longitudinal movement of needles (42) and with a needle selector device (21/22) which is likewise movable relative to needle bed (25);

• each needle (42) has one fixed butt (44) and one butt (47) which can be moved transversally to the direction of needle movement out of the range of influence of the longitudinally movable cam parts (16-20) of the cam system, a selector jack (50) being associated with each needle (42), which selector jack is mounted movably in needle bed slot (40) the same as the longitudinally movable needles (42), and also is pivotable, and a selector butt (55), on which can press a selector part (22) at the selector point (21) of the needle selector device (21/22), at least one operating butt (23, 54), which can be effected by controllable press cam parts (33-35, 33'-35') of the cam system, and presents a pusher butt (52) on which, selector jack (50) being selected, one cam part (23, 24) acts on each side of selector point (21) of the needle selector device for longitudinal pushing of selector jack (5), which bring about a longitudinal movement into different positions (I, II);
• and the cam system for either direction of movement presenting a pair of adjustable draw-off cam parts (15, 17), which cause the different draw-off strokes of needles (42) and of which the one (15) acts on fixed butt (44) while the other (17) acts on adjustable butt (47) of needles (42), and a separately controllable press cam part (33-39, 33'-39') being provided for each position (Q, I, II) of selector jacks (50).
