Problems solved by technology

[0007] In Patent Document 1, since a large hole is formed over half or more of the length of the bottom of the slider groove, the strength in the thickness direction of the needle body is low.
In particular, in flat knitting machines with a fine gauge, the thickness of the composite needle may be less than 1 mm, and the composite needle of Patent Document 1 may be insufficient in strength.

Embodiment approach 1

[0042] based on figure 1 , 2 The compound needle 1 according to Embodiment 1 will be described. figure 1 The top and bottom of the paper are the front and rear of the composite needle 1, the right and left of the paper are the bottom and top of the composite needle 1, and the direction perpendicular to the paper is the thickness direction of the composite needle 1. in as figure 1 (C) Sectional view of figure 2 Among them, the direction perpendicular to the outward direction of the paper surface and the way vertical to the inward direction of the paper surface are the front and rear of the compound needle 1 respectively, the right and left of the paper are the bottom and top of the compound needle 1 respectively, and the upward and downward directions on the paper are the compound needle 1 the thickness direction.

[0043] Such as figure 1 As shown in (A), the composite needle 1 includes: a needle body 2 having a hook 20 ; and a slider 3 slidably combined with the needle ...

Embodiment approach 2

[0059] In Embodiment 2, based on image 3 , 4 A compound needle 1 having a structure different from that of the first embodiment will be described. image 3 , 4 The observation method is the same as that of Embodiment 1 figure 1 , 2 same in image 3 , 4 In , members having the same functions as those in Embodiment 1 are assigned the same reference numerals as in Embodiment 1. FIG. In the following, this embodiment will be described focusing on differences from Embodiment 1. FIG.

[0060] The main difference between the needle body 2 of this example and the needle body 2 of Embodiment 1 lies in the shape of the waste discharge window 4 included in the needle body 2 . A part of the waste discharge window 4 of this example is formed in a solid portion on the rear end side of the slider groove 21 in the sliding direction. The upper edge surface 40 and the lower edge surface 41 are formed in the solid portion of the garbage discharge window 4 . The waste discharge window 4...

Abstract

The invention provides a compound needle which has sufficient strength and is not easy to retain garbage in the slot of the slider. The compound needle (1) has: a needle body (2), which has a needle hook (20) arranged at the front end and a slider groove (21) arranged on the upper end surface; and a slider (3), which is slidably embedded in the guide The needle slot (21) opens and closes the needle hook (20), wherein the composite needle (1) is equipped with a waste discharge window (4), and the waste discharge window (4) and the slider in the slider groove (21) The part on the rear end side of the sliding direction of (3) is connected, and an opening is formed on the side of the needle body (2). The shape in which the rear end of the part of the needle piece (3) that is in sliding contact with the bottom (21b) of the slider groove (21) is accommodated.

Description

technical field [0001] The present invention relates to a compound needle including a needle body and a slider. Background technique [0002] As a knitting needle used in a flat knitting machine, a compound needle is known in which a needle body having a hook and a slider for opening and closing the hook are relatively movable (for example, Patent Document 1). In this compound needle, the slider is slidably fitted into the slider groove formed on the needle body. [0003] In compound needles, waste such as dust and yarn scraps generated when knitting knitted fabrics on a flat knitting machine tends to accumulate in the slider groove. If the debris stays in the slider groove, the sliding of the slider will be hindered, and the hook may not be fully opened or stitch formation may become unstable. In view of such a problem, Patent Document 1 discloses a structure in which a hole (cleaning portion) is formed in a range not less than half the length of the bottom of the slider ...
