Description

[Detailed explanation of the invention] 〓Industrial field of use〓 This invention is applicable when knitting pile fabric with a flat knitting machine.
This invention relates to a sinker for locking knitting yarn to form a pile.

<Prior Art> It is known to perform pile knitting using a sinker in a flat knitting machine (see Patent No. 1337595). To perform pile knitting using a sinker (see Fig. 5), a hook 2 for ground yarn is provided at the bottom of the tip of the sinker 1, and a hook 3 for pile thread is provided at the top, and the sinker 1 is connected to the needle 4. In synchronization with the downward movement of the needle 4, the needle 4 is advanced from the state shown in FIG. 3A to the state shown in FIG. The sinker 1 is advanced with the pile hook 3 interposed between the ground yarn 8 and the pile yarn 9 fed from the base yarn 8 and the pile yarn 9.

In the state shown in Fig. 3C when the needle 4 is at its lowest position,
The ground yarn 8 is held by the ground thread hook 2, and the pile thread 9 is locked by the pile hook 3, and both threads 8, 9 are held one after another by the subsequent lowering of the adjacent needles 4, 4, . . .
are bitten by the hooks 5, 5, . . . of the needles 4, 4, . . . and form a ground structure and a pile structure.
Then, the ground structure and the top loop 1 of the pile
0 and 11 are in a state where they are hooked on the shank 12 of the needle 4. At this time, loop 1 of the ground structure
0 is pulled downward by the weight of the continuous knitted fabric and is in close contact with the shank 12, but the pile loop 11 has a larger loop diameter than the loop of the ground weave, so the needle 4 shank 1
It will be in a floating state compared to 2. At this time, the yarn for knitting the next course is fed, and when the needle 4 begins to descend, the latch 13 of the needle 4 passes through the inside of the pile loop 11, as shown in FIG. This sometimes caused damage to the knitted fabric and damaged the pattern.

〓Problems to be solved by the invention〓 In view of the above-mentioned points, the present invention is designed to separate the loops of the fabric weave that are attached to the shank of the needle and the pile loops when knitting pile fabric with a flat knitting machine. The purpose is to prevent the latch of the needle from passing through the inside of the pile loop when the pile loop is raised and the needle is lowered to knit the next course.

〓Means for solving the problem〓 A sinker having a hook for ground thread and a hook for pile has a hook on the side surface of the base of the hook for ground thread when the sinker advances toward the needle. A small protrusion is provided to hold the pile loop between the side of the shank and the side surface of the shank.

〓Effect〓 When the sinker advances toward the needle, the small protrusion provided on the side surface of the base of the sinker hook for ground yarn comes into contact with the loop of the ground weave and the pile loop that are latched to the needle, and the thread is further tightened. As the sinker advances, the loop is sandwiched between the small protrusion and the side surface of the shank, and is pushed in the direction of the tooth opening, eliminating the raised part, and the pile loop is brought into close contact with the shank with its tip, similar to the loop in the ground tissue. become,
Even if the needle descends further, the tip of the latch will not pass through the pile loop.

〓Example〓 Next, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, needles 4 are provided on both sides of the center of symmetry with respect to the center line L, and are slidably fitted into the needle bed. Also, the sinker 1 is movable forward and backward from the direction perpendicular to the needle 4.
is provided by a sinker bed 1 (not shown). The sinker 1 is in the form of a plate, and has a hook 3 for pile yarn and a hook 2 for ground yarn at the top and bottom of its tip. A small protrusion 22 is provided on the side surface of the base of the thread hook 2. The small protrusion 22 has a height that allows the knitting yarn constituting the pile loop to be held between the small protrusion 22 and the side surface of the shank 12 of the adjacent needle 4 when the sinker 1 advances to the side surface of the shank 12 of the adjacent needle 4. be.

Now, in the state shown in FIG. 1A, the needle 4
Then, the ground yarn and the pile yarn are fed by a ground yarn feeder and a pile yarn feeder (not shown), and the needle 4 is lowered and the sinker 1 is advanced. At this time, both the loop 10 and the pile loop 11 of the ground structure knitted in the previous course are locked to the shank 12 of the needle 4, but the pile loop 11 is separated from the shank 12 with its tip floating. However, the base of the loop is supported by the tip of the needle bed 23.

Furthermore, when the sinker 1 advances as shown in FIG. 1B, the small protrusion 22 of the sinker 1 enters between the parallel needles 4, 4, . When the needle advances as shown in FIG. 24 to bring the pile loop 11 and shank 12 into close contact. The needle 4 is also descending in response to the advance of the sinker 1, but when the tip of the latch 13 descends to the position of the pile loop 11, the pile loop 11 is completely moved in the direction of the tooth opening 24 by the small protrusion 22. Since the latch 13 is pushed in, the tip of the latch 13 passes through and descends without passing through the pile loop 11.
Then, with the hook 5 of the needle 4 locking the newly fed ground yarn and pile yarn, the thread is passed through the loop 10 and the pile loop 11 of the ground weave to form the loop 10 and the pile loop of the new ground weave. Make 11.

〓Effect of the invention〓 When the sinker of this invention advances toward the needle, the small protrusion provided on the side comes into contact with the pile that is locked to the needle, and the sinker of the present invention makes contact between the shank of the needle and the top surface of the small protrusion. Since the pile is pushed in the direction of the tooth gap while holding the pile, even when the needle descends, the tip of the latch engages with the pile loop, and as the latch descends inside the pile loop, the pile loop It is possible to eliminate the occurrence of problems in knitting fabrics, such as the needle hook getting caught in the knitted fabric.
