Abstract: A yarn feeder is caused to perform a single reciprocating motion in a section in which the boundary of an intarsia pattern varies discontinuously such that a jump occurs between a yarn feeding end position of the yarn feeder and a following yarn feeding start position, and thus the stitches of the section in question are formed in halves between an outward route and a return route. As a result, yarn jumps do not occur even when the boundary of the intarsia pattern varies discontinuously.

Abstract: The invention provides a method by which a transit yarn fastening portion can be formed with a comparatively small number of steps by a flat knitting machine. The method of forming a transit yarn fastening portion is performed in a method of forming, by a flat knitting machine including a yarn carrier and two needle beds, a knit fabric having a transit yarn section in which a yarn from the yarn carrier is not knitted and forms a transit yarn portion and a knitting section in which the yarn from the yarn carrier is knitted, and includes the steps of successively forming two or more loops of the transit yarn by one of needles of that one of the needle beds which does not contribute to knitting which needle is located in the proximity of a boundary between the transit yarn section and the knitting section, and transferring the loops formed in the first step to one of needles on the other needle bed which contributes to knitting.

Abstract: In a method for the production of intarsia knitted pieces on a flat-bed knitting machine, at least some of the yarn guides associated with each one of the intarsia areas and the respective needle bed are moved in a direction relative to each other when one of the needle beds is traversed in both lift directions by a carriage provided with one or a plurality of cams in the border area between two areas of intarsia, and the yarn guides are being coupled with the movement of the carriage in each intarsia area. At the end of a movement segment which extends at most across a number of intarsia areas corresponding to the number of cams, the carriage is reversed in its lift direction and returned, together with the yarn guide last used as well as with the yarn guide to be used for the following intarsia area, to the intarsia area last produced, without making a needle selection.

Abstract: A method for knitting a flat knitted fabric, wherein all knitting needles of the flat knitting machine are individually connected to an actuator, and each actuator of the corresponding knitting needle is activated in accordance with the predetermined knitting plan, and a flat knitting machine for implementing the above-mentioned knitting method. Preferably a linear direct current motor is used as the actuator. The flat knitting machine in accordance with the present invention can be operated at a higher speed than known conventional knitting machines and can provide a novel flat knitted fabric which cannot be knitted by the conventional flat knitting machine, by individually changing a retracting length of a needle.

Abstract: The machine comprises a knitting head (2), a camholder carriage (3) and several striping bars (7), on which thread guides (6, 6a) are mounted between two movable stop blocks (9, 9a) and are equipped with a thread catcher (21, 21a) and driven by fingers (25, 25a). Auxiliary drive means (11) for the stop blocks and a mechanism for attaching the thread guides automatically to the stop blocks, detachable by means of the drive finger (25), make it possible at any moment to shift the thread guides together with one of these stop blocks independently of the movement of the carriage, thus making it possible to move away the thread catcher when it stops knitting, in the production of INTARSIA knitted fabrics.

Abstract: An apparatus for selectively controlling yarn carriers for movement along with a carriage in a flat knitting machine. A trick location detector is provided on the carriage for detecting varying positions, expressed in terms of the number of tricks from one or the other tricked end of a needle bed, of the carriage on the needle bed during its run thereon. Coupling plungers in a plunger box on the carriage are controlled by solenoids in such a way that the plungers each is actuated to slide to its operative position relative to one of the yarn carriers for engagement therewith so that the yarn carrier so engaged by the plunger is carried along by the carriage over the predetermined distance.

Abstract: A knitting machine includes a knitting carriage, guide bars for thread guides having plunging yarn hook/feeders and a thread guide control device. A control device is integral with the knitting carriage. The control device cooperates with at least one thread guide formed of a cam having faces defining at least three different plunging levels and actuating the plunging yarn hook/feeders located on its pathway, independently of the direction of motion of the knitting carriage.

Abstract: A method and apparatus are disclosed for knitting sections of predetermined contour and/or of a design of the Intarsia type of predetermined shape in which a yarn guide member is moved along a bank of needles in a knitting machine between a pair of carrier splicing blocks which are movably mounted in the machine. The positions of these blocks are selectively variable, and a releasable latch arrangement connects the yarn guide to a splicing block during movement thereof in order to automatically vary the starting position of the next stitched row.

Abstract: A flat bed knitting machine having a motor driven carriage is provided with control means which counts needle slots as the carriage moves beyond working needles at one end or the other of the bed of the machine, and is effective when a predetermined count is attained to cause the motor to reverse the direction of movement of the carriage.

Abstract: In order to produce an inlay-type pattern on a flat-bed knitting machine, a plurality of thread guides carrying differently colored threads are mounted on respective slides which are movably supported, in pairs, on horizontal guide bars above a needle bed. Each slide coacts with a pair of adjustable stops limiting its reciprocation along the guide bar, another slide taking over the thread feed at the point where a previously active slide is arrested. In order to prevent the thread of the first slide from being engaged by the needles simultaneously with the thread of the second slide, the thread guide of the first slide is swung back from a leading to a trailing position upon reaching the end of its run in one or the other direction; this repositioning of the thread guide is accomplished by a pair of feelers contacting the associated stops.
