Definitions
- the present invention relates to a composite needle comprising a needle body and a slider attached to a needle bed of a knitting machine, and more particularly to a composite needle in which a tongue of a slider is formed by superposing two blades.
- This composite needle is accommodated in a state where two blades of the slider are superimposed on a blade groove formed in the needle body.
- the thickness of the blade is made smaller than the groove width, a gap is provided between the blade and the groove wall, and the blade is supported so as to be able to advance and retreat in the groove. Therefore, the position of the blade in the width direction of the blade groove becomes unstable by the amount of the gap. This causes the problem of indeterminate blade centering in the groove. In particular, when the stitch is placed on the tongue at the tip of the blade, this problem becomes remarkable when the lateral tension from the knitted fabric to the stitch is large.
- the slider advances and the tip of the tongue Abuts on the tip of the hook and separates into two parts.
- the regular route that the hook is closed with the hook sandwiched from both sides cannot be taken, causing a collision with the hook or the blade branching off at the hook tip.
- the hook advances along one side of the hook, a malfunction may occur, which may affect the durability and knitting of the needle.
- the blade Even if the blade is branched at the tip of the hook and guided to the regular route, at the transfer position where the blade advances further beyond the hook, the blade extends diagonally straight along the side surface of the hook, and thus is viewed in plan. In this case, the tip portion widens in a fan-like manner from side to side.
- This has a needlebed arranged opposite to the front and rear pair, and a knitting member such as a sinker and a loop presser is arranged adjacent to the compound needle on the needlebed, and This is a problem for flat knitting machines that move forward and backward. It is conceivable that during transfer, the blade approaches the knitting member and closes the space for transferring the loop placed on the tanda to the receiving needle, causing problems in knitting. Disclosure of the invention
- the needle body includes a needle body having a hook at a tip thereof, and a slider having evening formed by stacking two blades, and a blade groove of the needle body is formed in a blade groove formed in the needle body.
- the blade side face is pressed against the groove side wall in the blade groove of the needle body, and the tip of the blade in the groove width direction
- a centering means is provided to hold the sides at positions equally distributed to the left and right from the center of the groove width (hereinafter referred to as centering).
- the centering means is a bend provided on each blade. Formed.
- the bend portions are formed so as to be separated from each other so as to open the mouth of the blade tip when the blade is exposed from the blade groove and advances toward the hook.
- the compound needle is configured as a transfer needle for allowing the tip of the blade of the slider to further advance beyond the hook and performing the transfer at the advanced position, and the bend is configured to allow the tip of the blade to extend beyond the hook.
- the blade is formed so as to narrow the gap at the tip of the blade when entering the transfer position.
- the bend is formed at a blade portion completely exposed from the blade receiving groove at the transfer position.
- the composite needle is configured as a transfer needle for the tip of the blade of the slider to further advance beyond the hook and performing the transfer at the advanced position, and the tip of the two-layered blade extends beyond the hook.
- the bends of the blades were formed so as to push each other so as to narrow the gap between the blade tips when moving to the transfer position.
- the centering means is configured such that one of the upper edge and the lower edge of the blade is pressed against the blade groove side wall.
- the centering means is formed by a swist provided on a blade.
- the composite needle composed of the needle body and the slider is accommodated and supported in a blade groove formed in the needle body with one blade portion of the slider.
- Each blade of the slider is provided with a ring ring.
- a bend is provided as a centering means at the part that goes in and out of the blade groove. The bend provided on each blade presses the side of each blade against the groove side wall, and the gear formed between the blade groove and the blade ⁇ : Works to center on the center of the groove width
- the blade is centered in the groove when the slider moves relative to the needle body and closes the hook, and the blade tip branches off when the tip of the tongue contacts the tip of the hook.
- the hook can be more securely closed with the hook clamped from both sides.
- the centering means By configuring the centering means so that either the upper edge or the lower edge of the blade is pressed against the side wall of the blade groove, the gap between the blade and the blade groove can be filled and the blade can be centered. Since the tongue at the blade tip is widened by the action of the swivel, the blade can be more reliably branched by the hook.
- the compound needle When the compound needle is configured as a transfer needle that allows the slider blade tip to extend further beyond the hook, the blade tip moves to the transfer position beyond the hook.
- the blade tip By forming a bend to suppress the spread of the gap at the tip, the blade approaches the knitting member even in the case of a knitting machine in which knitting members such as sinkers and loop pressers are arranged adjacent to the compound needle.
- knitting members such as sinkers and loop pressers are arranged adjacent to the compound needle.
- Can reduce knitting problems such as those encountered in This can be realized by forming the bend portions formed on the blade in a direction in which they press against each other, or by forming them in a direction away from each other.

- the hook member 7 includes a hook portion 15 from the tip end side, a receiving groove 17 for accommodating the blade 11, a slider body portion 13, a main body central portion 19 supporting the lower arm portion 39, and a rear portion.
- a recess 21 is provided to connect the tip of the jack 9.
- the hook member 7 and the jack 9 have the same thickness and are formed slightly thinner than the needle groove width.
- the jack 9 has a curved elastic leg 23 extending rearward from the recess 21 and having a rear end in contact with the bottom of the needle groove.
- a control battery 25 is protruded near the center of the body of the jack 9 and engages with a cam provided on a cam carriage (not shown) to move the needle body 3 forward and backward.
- the slider 5 comprises blades 11a and 11b and a slider body 13 as a separate member.
- the blade 11 is formed by stacking two plates having substantially the same shape, and is housed in the blade groove 17 of the hook member 7.
- the blade 11 has tangs 31 a and 31 b at the tip end thereof that abut against the hook tip 15 a, and is further provided at the rear side of the blade groove 17 for connection with the slider body 13.
- Connection parts 33a and 33b are provided.

- Reference numeral 39 denotes a lower arm portion branched from the main body portion, and extends into the main body central portion 19 of the hook member 7.
- a longitudinal groove 51 is formed by cutting one side surface of the lower arm portion 39, and a through hole 53 is provided on the longitudinal groove 51.
- the protrusions 33a and 33b of the blade 11 are connected and fixed to the through holes 53 of the slider body 13 by caulking or the like.
- the rear end 41 of one of the blades 11a extending to the longitudinal groove 51 is bent and pressed against the side wall of the needle groove to move the needle 5 along with the movement of the needle body 3 when the needle body 3 moves forward and backward.
