Embodiment approach 1

[0105] Fig. 1(A) is a front view of the selector jack of the present invention, and Fig. 1(B) is a bottom view of the selector jack. Fig. 2 (A) is the front view of the spacer of the present invention, Fig. 2 (B) is the bottom view of the spacer, and Fig. 2 (C) is an enlarged view of the part surrounded by the circle of Fig. 2 (B).

[0106] The shape of the selector jack 6 viewed from the front is a long piece having substantially the same shape as a conventional selector jack. However, when the selector jack 6 is viewed from below, it is straight without bending in the thickness direction, unlike conventional selector jacks. In this selector jack 6 , a base point engagement portion 6A is provided at a front end portion 66 on the tooth mouth side, and a recessed portion 6B is formed in the vicinity of the lower side of a butt 61 described below. And, the front end portion 66 side of the needle selector 6 is provided with a butt 61 for descending, and the tail portion 64 side ...

Embodiment approach 2

[0116] In Embodiment 2, unlike Embodiment 1, a needle selection mechanism of a flat knitting machine using a knitting needle K in which a partially bent portion is formed on a selector jack instead of a spacer will be described. The needle selection mechanism of this embodiment is the same as that of Embodiment 1 except that the shapes of the spacer and the selector are different. Therefore, the description will focus on differences from Embodiment 1. FIG.

Abstract

Provided are a needle selection mechanism in which a needle selection error is less likely to occur even when a carriage is moved at high speed, and a selector and a spacer used for the needle selection mechanism. The needle selection mechanism for a weft knitting machine has a spacer (7) held at a predetermined position in a needle groove formed in a needle bed, and also has a selector (6) slidably placed in the needle groove so as to be parallel with the spacer (7). The spacer (7) is a linear long piece and has a spacer-side sliding resistance generation section (elastic bend (71)) formed to face the selector (6). The selector (6) is a linear long piece and has a base point engaging section formed at the front end side of the selector and engaging with an installation section secured in the needle groove to position the selector (6) at a base bottom position and the selector (6) also has a selector-side sliding resistance generation section (push out piece (65)). The selector-side sliding resistance generation section and the spacer-side sliding resistance generation section are formed so as to limit the area where sliding resistance of the selector (6) is generated by mutual contact between the sliding resistance generation sections.

Description

technical field [0001] The invention relates to a needle selection mechanism of a flat knitting machine, a needle selection piece for the needle selection mechanism of the flat knitting machine and a spacer for the needle selection mechanism of the flat knitting machine. Background technique [0002] Conventionally, in a flat knitting machine, the knitting needles sliding in a plurality of needle grooves arranged in parallel with the needle bed are driven by a knitting cam system mounted on a carriage that reciprocates along the length direction of the needle bed, to carry out the knitting action (for example, refer to Patent Document 1). The basic movements of knitting are loop forming, tucking and floating. The protruding position of the knitting needle toward the crest side is the most prominent entry position during knitting, the middle position during tucking, and the base position on the opposite side of the crest when floating. [0003] These knitting actions are pe...
