Embodiment 1

[0045] figure 1 A schematic configuration of the flat knitting machine 11 according to the first embodiment of the present invention is shown as viewed from the needle bed side in the vicinity of the front end of the needle bed 2 . On the needle bed 2, needle grooves 2a are formed at equal intervals along the longitudinal direction which is the left-right direction in the figure. The knitting needle 3, the movable sinker 14, the yarn guide spacer 15, the spacer 6, and the like are accommodated in each needle groove 2a. The movable sinker 14 has a Figure 8 The knitting yarn holding portion 14a, which is the same as the knitting yarn holding portion 4a, has an elongated hole 14b formed in the sinker groove 2c formed at the front end portion of the needle bed 2 including the top teeth 2b to be displaced. In the lower part of the part where the yarn guide spacer 15 protrudes toward the tooth mouth side, a Figure 8 The yarn guide 5a is the same as the yarn guide 15a.

Embodiment 2

[0061] Figure 7 It is a partial plan view showing a schematic configuration of a flat knitting machine 21 according to Embodiment 2 of the present invention with respect to the vicinity of the front end of the needle bed 22 . and figure 2 Likewise, needle grooves 22a are formed between the needle plates 18 upright on the needle bed 22, top teeth 22b are formed at the front end facing the needle bed 20, and sinker grooves 22c are formed near the top teeth 22b. In each needle groove 22a, the movable sinker 14, the knitting needle 3, and the yarn guide spacer 25 are accommodated. On the yarn guide spacer 25, it is also set as Figure 4 The yarn guide portion 15a of the yarn guide spacer 15 shown in (b) etc. is the same as the yarn guide portion 25a. In addition, only three knitting needles 3 housed in the needle groove 22a are shown, and other illustrations are omitted.

Abstract

There is provided a flatbed knitting machine provided with movable sinkers that can reliably prevent a knitting yarn from dropping into a space between the movable sinker and a sinker groove even though a front end of a needle bed is formed to be a top tooth. A movable sinker (14) is provided with a elongated hole (14b) so as to be capable of rocking displacement in a state where a leading end of a yarn drop preventing portion (15b) extended from a yarn guide spacer (15) inserted into the elongated hole. The yarn drop preventing portion (15b) covers a space produced between a sinker groove (2c) and the movable sinker (14) on a side where the movable sinker (14) is disposed next to a knitting needle (3), so that it is possible to reliably prevent a knitting yarn from dropping. The yarn guide spacer (15) is formed of a metal plate-shaped material, and the yarn drop preventing portion (15b) is formed on the leading end side of an extended portion (15c) extended to cross the bottom part of a needle groove (2a).

Description

technical field [0001] The present invention relates to a flat knitting machine in which at least a pair of front and rear needle beds face each other across a tooth bed, and are provided with a movable sinker arranged at the front end of the needle bed on the tooth bed side and capable of advancing and retreating at the tooth bed. Background technique [0002] Conventionally, a flat knitting machine equipped with a movable sinker capable of advancing and retreating at the needle bed has been used to push down the knitted fabric under knitting under the bed bed. A part of this movable sinker is inserted into a sinker groove formed at a position close to the front end of the needle bed, and a knitting yarn holding portion is formed at the front end protruding toward the needle mouth side. The movable sinker is swingably supported at a position spaced from the tooth bed, and the knitting yarn holding part can push down the knitted fabric to a deep position below the tooth bed ...
