Abstract: A yarn guiding apparatus for a flat knitting machine in which a pair of opposed needle beds defines a knock over edge area and a center line therebetween. A yarn holding member is arranged between a needle and a sinker mounted on a needle bed. The yarn holding member is moveable relative to the knock over edge area and has an operating face for pushing down a yarn fed from a yarn feeder to the knock over edge area. The operating face is configured for contacting the yarn and for pushing the yarn down toward a needle when the yarn holding member is advanced toward the knock over edge area. The yarn holding member is advanceable to a position in which a portion of the yarn holding member extends beyond the center line defined by the opposing needle beds.

Abstract: Different kinds of texture samples smaller than the knitted fabric to be produced are knitted with different loop lengths and finished. The loop length and loop density for the fabric are determined from the sample having an optimum texture. The density obtained is applies to pattern data as to the fabric to determine wale and course numbers, and the fabric is knitted with the determined loop length and finished.

Abstract: A presser controller device of a carriage in a flat knitting machine in which the carriage comprises: cams that project from the carriage for urging selector jacks of corresponding knitting needles which are parallelly arranged on a needle bed of the traverse knitting machine; cam lift-down plates arranged in parallel therein for actuating their respective cams for upward and downward movement; holding means for holding selected ones of the cam lift-down plates in a given location; springs coupled to their respective cam lift-down plates for constantly urging them in one direction; and actuating means for pressing the cam lift-down plates for displacement while resisting the yielding force of the springs.

Abstract: A flexible cable support is provided in a flat knitting machine for supporting power supply cables. The flat knitting machine comprises a carriage that reciprocates along a needle bed. The flexible cable support and the power supply cables are connected at one end to a terminal unit on the needle bed at a position representing approximately the middle of the travel path of the carriage. The other end is connected to the reciprocating carriage. The flexible cable support is composed of a series of joint sections pivotally connected to each other forming a continuous flexible support so that, as the carriage reciprocates, the cables supported on the flexible support are allowed to freely bend and move with the carriage.

Abstract: 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.

Abstract: In the apparatus for drawing down knitted fabrics, a fixed position roller, a pressure roller and a drive for the rollers are located below mountainously opposed needle heads. The contact pressure between the rollers is controlled by a pivot mechanism including a cam driven by a motor and a spring connected to the cam and also connected to a pivot arm supporting the pressure roller. Rotation of the cam controls the spring force exerted on the pivot arm by the spring and thus controls movement of the pivot arm to lessen or increase contact pressure between the rollers.

Abstract: A set-up comb 6, disposed below the gap 3 between needle beds in a V-bed flat knitting machine, comprises a comb bed 5 and a plurality of setting-up needles 4 mounted to the comb bed 5. Each setting-up needles comprises a needle body 10 fixed to the comb bed 5 and a slider 11 slidably combined with the needle body 10. The needle body 10 has a hook accommodating protrusion 20 formed at its front end for releasably receiving therein a hook 12 formed at the upper end of the slider 11. When the slider 11 is elevated, the hooks 12 retract into the hook accommodating protrusions 20 of corresponding needle bodies 10 and thus the set-up yarn 75a, 75b engaged by the hooks 12 are disengaged from the hooks.

The presser bar may be moved in the rocking motion toward and away from needle beds of the knitting machine and these beds have a space between them to allow entry of the presser bar. A reversible motor is associated with the pressure bar supporting arm to move the presser bar into and out of the spaced needle beds. First and second proximity sensors are provided to detect whether the presser bar is advanced into the range for a knitting operation or is retracted into a range for a knitting operation.

Abstract: A set-up comb 6, disposed below the gap 3 between needle beds in a V-bed falt knitting machine, comprises a comb bed 5 and a plurality of setting-up needles 4 mounted to the comb bed 5.
