Abstract: New stitches on knitting machines are formed by producing two stitches from one stitch suspended on a knitting needle, in that the stitch suspended on the knitting needle is transferred by a transfer element associated with the knitting needle and subsequently a new stitch loop is pulled from the knitting needle through the stitch suspended on the transfer element.

Abstract: When a new yarn is received by a hook to form a new stitch loop, to prevent old stitch loops from going beyond the top end of the slider and being knocked over, the advanced position of the slider into the trick gap is maintained, and the new stitch loops are pulled into the old stitch loops. Next, the hook of a compound needle of the opposing needle bed is inserted into the old stitch loop, and said slider is lowered and retracted, and at the same time, the old stitch loops are transferred onto the hooks of the opposing needle bed to make split knit.

Abstract: A tubular knitted fabric is broadened while fully preventing generation of open gap. Yarn is hooked on a needle of a second needle bed and twisted to form a loop, and this loop is transferred onto a first needle bed to become a broadening loop. A subsequent stitch is formed on the broadening loop and transferred back to the second needle bed. Yarn is hooked again on a needle of the second needle bed and twisted to form a loop, and this loop is transferred to the first needle bed to become a broadening loop.

Abstract: In a flat knitting machine wherein a plurality of knitting locks work on a single needle bed to knit, the consumption of each yarn is measured and compared with the standard yarn length, and the stitch cam adjustment values of the respective knitting locks are corrected. The stitch cam adjustment data is stored for the respective combinations of stitch cams and yarns. Correction is not limited to the stitch cam which knitted the yarn of which consumption was measured. Correction by the same value is also given to the stitch cam adjustment values of other stitch cams relative to the yarn. As a result, for any combination of a stitch cam and a yarn which appears suddenly in the latter half of knitting, the stitch cam adjustment values have been corrected on the basis of the measurement of consumed yarn lengths of other stitch cams, generating no knitting gaps.

Abstract: A stitch increasing needle operating cam for a flat knitting machine having stitch increasing function. The needle operating cam for operating needle bodies and sliders of compound needles separately from each other, in which in relation to a lowering face of a needle body lowering cam of a loop delivering side cam, a slider lowering face for lowering a slider at a timing earlier than that by the lowering face of the needle body lowering cam is provided.

Abstract: A stitch control mechanism for a flat knitting machine, for controlling loop size in knitting a knit fabric on a flat knitting machine. A spiral cam plate is attached to one surface of a stitch cam control cam, the spiral cam plate is held between a pair of cam rollers, and the pair of cam rollers are supported on a guide plate combined with a stitch cam and having a portion slidably fitted in a guide slot formed in a base plate.

Abstract: A knit run cam for vertically moving a needle when fabrics are knitted. There is provided a knit run cam comprising two cams having a needle butt lowering bevel overlapped in a range of at least a part of the same phase in a moving direction of a carriage, one cam having a needle butt lowermost position higher than the other cam.

Abstract: A device is designed to operate two slides to which corresponding stitch regulation cams are bound, and it includes: a plate, mounted on the carriage and located below the slides, that is able to be moved by means in relation to the carriage in the direction in which this latter is itself moved, two tracks, symmetrical in relation to a vertical plane, formed in the upper part of the plate, each constituted by flat horizontal surface and by a flat surface that follows on and inwards from the former, turning downwards, elastic means which keep the extremities of the slides in contact with the corresponding tracks.Movement of the plate in one direction causes the slide which is downstream in respect of the direction of movement to be lowered in proportion to the amount by which the former is moved.

Abstract: A carriage 14 is reciprocable along a needle bed of a flat knitting machine and carries a needle cam. A pair of stitch cams 12 and 13 are adjustably supported by the carriage 14 and are disposed so as to trail behind the needle cam in alternate strokes of the carriage, respectively. An adjustment mechanism 11 includes a stepping motor 38 (FIG. 3) which adjusts the trailing stitch cam 12 or 13 not only at the beginning of the respective stroke but also during the course of the stroke itself, thereby enabling the stitch density to be varied within each row of the knitted article as well as from row to row.

Abstract: The present invention relates to a flat knitting machine capable of changing the stitch size of an optional wale in every course, and this flat knitting machine comprises a selector actuator for selecting needles to be raised to a knitting or tucking position, select jack pressers for locating at lower butt positions butts of select jacks for operating needles or corresponding jacks raised to a knitting or tucking position, and a pair of upper and lower piled knitting cams, the upper knitting cam being a knitting cam for higher butts, which is brought into butting contact with higher butts, and the lower knitting cam being a knitting cam for lower butts, which is brought into butting contact with lower butts, wherein the stitch size can appropriately be changed by changing the position to which the needles are brought down by said knitting cams.

Abstract: A flat knitting machine includes a device for adjusting the retractor elets for the needles in the cam systems on the carriage of the machine for the setting of the stitch tension. In order to simplify the tension adjusting mechanism and simultaneously to produce a sensitive setting mechanism, there is provided on the carriage a single electrical stepping motor, with position sensor, for counterbalanced adjustment of the leading and of the trailing retractor elements of each cam system.

Abstract: Knitting machine with at least one needle bed in which knitting tools exhibiting feet are mounted for camming up and camming down, with at least one cam transportable past the feet and influencing the latter, which exhibits at least one cam-down part mounted movably but lockably and unlockably and adjustable as to its cam-down depth, and with a switching apparatus arranged outside the needle bed which exhibits means for unlocking, means for adjusting and means for locking the cam-down part, while the means for adjusting the cam-down depth exhibit an adjustable guide rail intended to slide the cam-down part and a switching device to adjust the guide rail according to pattern before the cam-down part rides up (FIGS. 1 and 6).

Abstract: A flat knitting machine comprises a needle bed and a carriage traversible along the needle bed. Stitch cams presettable in a plurality of different positions according to a desired knitting pattern are provided, and an adjustably positioned ramp in the needle bed fixed to a slide is adapted to displace a cooperating stitch cam into a selected position. Means are provided on the carriage for clamping the stitch cam in the position to which it has been displaced by the ramp and a slide to which the ramp is attached is raisable by control cam means preceding knitting cams in the carriage.
