A sinker is disposed at the front end of a needle bed of a flat knitting machine so as to be capable of swinging displacement. A groove guiding advancing, retreating and swinging of the sinker is formed at the front end of the needle bed. A knitting yarn holding part is formed at the front end of a sinker plate. A knitting yarn drop preventive part, for preventing knitting yarn between a knitting needle and the sinker from dropping into the groove during knitting, is disposed adjacent to the sinker.

Sinker mechanism for flat knitting machines having yarn drop prevention

In a needle bed in which plural rows of needle plate grooves are provided in a lower needle bed base, lower needle plates are inserted into the needle plate grooves, and a lower needle groove is formed between the lower needle plates, wherein a part of the lower needle plates is extended upwardly, the extended portion serves as an upper needle bed supporting member, a fixing member for stopping an upper needle bed base is provided on the upper needle bed supporting member, and an upper needle bed base is supported above the lower needle bed by the upper needle bed supporting member.

Upper needle bed support for V-bed knitting machine

There are disclosed improvements in flat knitting machines incorporating a plurality of carriages which respectively adjust the forward and backward movement of knitting needles mounted on respective needle beds, a pair of yarn guide rails which are respectively secured above and in the longitudinal direction of respective needle beds, and a plurality of yarn feeders which respectively feed yarns to knitting needles in association with those yarn guide rails while the carriages run themselves. The improvements comprise novel apparatus for arranging the yarn feeding apertures of the yarn feeders by lowering same to a predetermined position while controlling the shifting movement and stopping operation of the yarn feeders.

Apparatus for controlling displacement of yarn feeders

A flat knitting machine which can carry out changing of knock over timing and changing of an elevating amount of a needle, in which a knock-over plate provided at its extreme end with a loop pressing plate having an end edge in contact with a knitting yarn is inserted into a bottom of a needle groove of a head portion of a needle bed so that the knock over plate can be slidably moved in a direction of forward and backward movement of a needle. Further, a knock over plate cam for operating the knock over plate in engagement with the knock over plate is provided on a carriage, and the knock over plate is moved forward and backward by the cam.

Flat knitting machine

The multibed flat knitting machine has upper needle beds, lower needle beds disposed under the upper needle beds, respectively, with their heads located adjacent to those of the upper needle beds. Knock-over bits are placed in the heads of the upper needle beds so as to slide parallel to the sliding directions of the upper needles. The knock-over bits are capable of being advanced to a position where the loop holders of the knock-over bits are beyond a corresponding position of the needle hooks of the advanced upper needles to support the needle heads of the upper needles of the upper needle beds.

Knitting method of weft knitted fabric and multibed flat knitting machine

The present invention relates to a flat knitting machine provided with swing sinkers and presser bars which can move into and out from a space provided between two needle beds in relative relationship so that they effectively urge the loops or stitches of yarn. Accordingly, both plain and rib knitting operations will be carried out with ease.

Flat knitting machine with swing sinkers and presser bars

The invention sets forth a movable sinker which is to be disposed on a needle bed of a flat knitting machine, employing compound needles. The movable sinker is provided with a cam abutting part, a stopper with a pivot hole between the cam abutting part and the stopper, a front tip part includes a guide part with an inclined lower edge which guides the knitting thread to a stopping part. The guide part is so formed that the knitting thread supplied at the time of knitting by this flat knitting machine is securely guided in the hook part of the knitting needle, and the stitch pull-in amount of the carriage at the time of forming a stitch is reduced.

Movable sinker in flat knitting machine

A sinker mechanism which includes multiple knitting needles placed in parallel above a needle bed with each sinker being mounted so that it can rock up and down so that its tip descends between adjacent knitting needles. A yarn-catching hook is provided at one sinker end; downward pressure is applied by a spring that can be removed from and replaced into the sinker so the yarn-catching hook will drop between adjacent knitting needles, and this downward force is adjustable so the yarn-catching hook's position is a function of the tension in the yarn it is holding. The sinker is located in the cut-out portion of the needle plate with the capability to rock up and down so that its back end can be linked to the end of the needle plate, and that the plate and is configured so that an arm projects to touch the rear cam. A spacer is provided whose front end is adjacent to the sinker's middle portion when the sinker is joined to the needle plate, and the spacer's back end is joined to the needle plate beside the sinker at a point higher than the knitting needle.
