Abstract: It is an objective of the present invention to provide a method for knitting a novel knitted fabric in which a stitch direction on an instep side is orthogonal to a stitch direction on a sole side using a flat knitting machine. In a sole section (4), a pickup stitch (8) in which a cover section (3) continues to a left side and a right side of the sole section (4) is formed while moving a stitch row of a BB, which becomes a part of a toe section (2), toward one side (right) in a knitting width direction. In the cover section (3), a three-dimensional cover section (3) is formed by carrying out a narrowing knitting while forming a new stitch following a stitch row of an FB of the toe section (2), a stitch row of an BB of the toe section (2) in which the pickup stitch (8) is formed on a left side (12) and a right side (13) of the sole section (4) while being moved toward the right, and a stitch row of the pickup stitch (8).
Abstract: A knitting machine with multiple feeders may be utilized to knit a knitted component. Feeders may be used to knit the knitted component and a combination feeder may also inlay an inlaid strand within the knitted component. As an example, a combination feeder may include a feeder arm that reciprocates between a retracted position and an extended position. In manufacturing the knitted component, a feeder inlays the strand when the feeder arm is in the extended position, and the strand is absent from the knitted component when the feeder arm is in the retracted position. A dispensing tip disposed at the end of the feeder arm supplies the strand for inlaying in a location disposed below the intersection of the planes of the needle beds and for one or more of knitting, tucking, and floating in a location disposed above the intersection of the planes of the needle beds.

Abstract: In order to process yarn preliminarily, and to change over yarn precisely at a desired knitting position, the yarn fed to a flat knitting machine is processed by a yarn processing device. To change over the yarn at a changeover position of knitted fabric, it is necessary to actuate the yarn processing device preliminarily at an actuating position C. A controller calculates the actuating position from a set value in a setting circuit and pattern information from a memory. When an encoder detects that a position of feeding the yarn to a knitting needle has reached the actuating position, the yarn processing device is actuated. The length of the yarn from a yarn processing position to the actuating position is nearly equal to the sum of a knitting loop length from the actuating position to the changeover position.
Abstract: A yarn feed assembly for circular knitting machines for presenting one or more yarns chosen from a plurality of available yarns into the needle path under the control of a microprocessor. An arcuately movable sector-shaped yarn guide includes a plurality of openings therein for positioning a plurality of yarns in spaced parallel position with each other. A toggle clamp for each yarn located downstream from the yarn guide keeps the yarns taut in their normal stored position. To select a yarn for feeding to the feed station, a transfer arm selects the yarn positioned in a pickup position by the yarn guide. As the transfer arm begins to move, the corresponding toggle clamp releases, and the yarn is then fed onto its yarn feed location.

Each collar rack is designed to hold a plurality of yarn guide collars. The yarn changing device includes a collar support mechanism carried by the carriage for detachably holding a selected one of the collars. The collar support mechanism has three working positions including an operational position and two transfer positions. Each transfer position allows the transfer of the selected collar between the collar support mechanism and one of the support racks. A mechanism is also provided to change the position of the collar support in response to movements of the carriage relative to the needle bed. In a preferred embodiment, the position changing mechanism changes the position of the collar support mechanism in response to movements of the carriage relative to the needle bed.
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 yarn changing device for use in a flat-bed knitting machine having a carriage. The yarn changing device provides a relatively simple but effective arrangement for repetitive, alternating selection of any one of three or more yarns for knitting operation upon such successive reciprocation of the machine 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.
