Multi-system circular knitting machine with JacQuardmuatereinriohtun "

The invention relates to a vlelsyatemige circular knitting machine with a jacquard pattern device, which for each Knitting system has a pin drum which can be pivoted via pattern rockers in the rotating needle carrier mounted sample sinkers, which are each coupled to a tiltable and longitudinally displaceable needle punch, the needle punch via feet of a correspondingly vlelsystemigen needle = ram lock and the needles from one accordingly syotemlgen needle echioß of the machine are affected

The invention has for its object to provide a knitting machine with a JacquardeinriohtuBg, which has a much higher Syatemzahl as mowers known _s with Mustereinriohtungen provided knitting machines and on which the high Syatesnzalil gradient-free sample trpta with a huge rapport established, can be <>

Ea lat ready known to dispense with pronounced catching areas in order to reduce the length of the individual knitting systems of a circular knitting machine in order to increase the number of knitting systems arranged over the entire circumference of the machine in the needle lock part and also to shorten the length of the cam eccentric an additional shortening of the length of the knitting systems a steeper design of the angle of inclination of the Fhruxsgskanten of the lock parts could only be achieved at the expense of a »reduced running speed of the machine, because otherwise the needle feet would break Buren decided not to use a catching area in the lock systems, but in the known machines the knitting systems in no way affect the actual working area of the needles, namely the area of the needle drive mid dee need el = exhaust into the coulier position, limited »but also have an initial area in which all needles or the associated Stouerorgaaö for pattern

The invention takes this approach in solving the entrance-mentioned object, and is characterized in that the length jedea lock system, which determines the TJmfangsbereich each knitting system on the machine, the length of a needle cam system is limited, which consists only of a workspace _t in which the needles are driven out in the knitting position and withdrawn again via the coulier position into their starting position _B and that the control area of the assigned needle lock system at least partially overlaps the working area of the preceding pin lock system and the collection of all needle locks in the needle lock system for pattern selection for a knitting system completely in the overlapping area with the working area of the preceding needle lock system, i.e. in the area of the preceding knitting system of the machine

For this purpose, according to the invention, the needle picks are the machine with three feet, namely an Aus · = drive foot, a trigger foot and a tilt foot with three separate lock tracks of the needle pusher lock can cooperate ^ whereby the engagement of the shoot = Fußee and dee soft foot in the assigned lock railways.
