Abstract

To reduce the drive power consumption of a circular knitting machine by reducing the contact area of a tool for the knitting machine with the side faces of a thin groove to suppress a rise in temperature and the thermal deformation of the knitting machine by frictional heat. A part of the stem (17) of the tool for the circular knitting machine is raised from the bottom face (20) of the thin groove (19) in which the tool for the circular knitting machine is inserted and, at the same time, sunk from the upper end face (21) of the thin groove to form float parts (22, 22A to 22L) extending parallel with the thin groove (19). When a distance (L) between the bottom face and the upper end face of the thin groove (19) is used as a reference, the float part is so formed that its raised length (L1) is 10 to 40% of (L) and its sunk length (L2) is 10 to 40% of (L).

Abstract

Provided is a latch needle for a circular knitting machine, which has a relatively simple structure but can knit a double loop fabric stable in a fine gauge. In the circular knitting machine latch needle (7), a recess (8) is formed between a connecting portion (4) and a hook (5), and an angle (&agr;), which is formed by the inner wall (10) of the hook (5) together with the upper face (11) of the connecting portion (4), is made less than 55 degrees. It is preferred that the radius (Rb) of a curve to form the recess (8) is made less than 0.25 mm, that the step (H) between the recess (8) and the upper face (11) of the connecting portion (4) is at least 0.03 mm, and that the radius (Ra) of the inner wall (10) of the hook (5) is at least 1.0 mm.
