Claims

[Claims for Utility Model Registration] (1) Following a plate-shaped needle tip having a sharp end and a needle hole, a scarf surface is provided at a required angle to the thickness center line of the needle tip in the width direction. A scarf part and a shank part of a rod-like needle for a tufting machine, which is provided with a shank part with a circular cross section at the rear of the scarf part, can be freely rotated into a deep hole-shaped needle insertion part arranged horizontally in a row on a needle bar. By means of a set bolt inserted into the needle bar and aligned with the needle bar,
In a needle mounting structure of a tufting machine that presses and fixes the shake part from the same direction,
The shank part has a chord of the shank part, and with respect to the thickness center line in the width direction of the needle tip part,
A clearance angle adjusting part is provided which is cut out by a plane intersecting at an arbitrary angle selected in advance, and a pressing part consisting of a plane perpendicular to the advance/retreat direction of the set bolt is provided at the tip of the set bolt, and the pressing part is used to adjust the clearance. The needle mounting structure of the tufting machine features a structure in which the corner adjustment part is fixed by surface pressure. (2) Following a plate-shaped needle tip portion having a sharp end and a needle hole, a scarf portion having a scarf surface at a required angle with respect to the thickness center line in the width direction of the needle tip portion, and a scarf portion of the scarf portion. In a rod-like needle for a tufting machine having a shank portion with a circular cross section at the rear, the shank portion has a shape that forms a chord of the shank portion and is relative to the thickness center line in the width direction of the needle tip portion. ,
A needle for a tufting machine, characterized in that a clearance angle adjusting part is formed by notches formed by planes that intersect at a pre-selected arbitrary angle.
