Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitting method for welt yarns that are knitted using a knitting machine.

[0002]

2. Description of the Related Art In a conventional cam type knitting machine, the operation of a knitting needle is limited to three operations of knit, tuck, and welt,
In the case of the welt operation, the welt loop is formed by the operation in which the knitting needle does not move at all when the welt yarn is supplied from the yarn feeder. However, when forming a welt loop, there is no constraint point for the welt loop, so when we try to form a welt loop over multiple continuous needles, the welt yarn that forms the loop floats above the knitting machine sinker portion and continues. Generally, only a welt loop of about 5 to 6 needles can be formed. Therefore, in the case of so-called inlay knitting in which the weft insertion yarn is inserted into the weft knitted fabric, a tucking operation is performed at appropriate intervals to provide a welt loop constraint point.

[0003]

When the above-described inlay knitting is performed, the inlay yarn also has tack loops, and the inlay is not completely formed. Further, even when floating knitting, welts cannot be continued at long intervals, so that problems such as the need to form tuck or knit loops at appropriate intervals occur.

In view of the above problems, the present inventors prevent the welt yarn from rising from the knitting machine sinker portion at the time of forming a welt loop, and continuously or partially over the entire width of the knitting machine. An innovative knitting method in which a plurality of knitting needles each having an actuator are arranged as a knitting method for forming a loop, and a knitting motion can be performed by giving a sliding motion based on a predetermined knitting plan (JP-A-62-62). 282
No. 051)).

[0005]

That is, the first aspect of the present invention
Is a plurality of knitting needles each provided with an actuator and arranged in parallel in one plane, and a plurality of knitting needles that slidably support the plurality of knitting needles and extend left and right along the plane. Using a flat knitting machine comprising a knitting needle guide member that defines an interval between the knitting needle and a traveling table that reciprocates in the left-right direction along the knitting needle guide member, the travel table including at least one yarn supplying device, The position of the yarn supplying device on the traveling platform is detected, and a signal based on a predetermined knitting plan is applied to the actuator of each corresponding knitting needle, whereby the knitting needle slides based on the predetermined knitting plan. In the knitting method of a knitted fabric in which a knitting motion is performed by giving a motion, the knitting needle is maintained in a state where the knitting needle is raised to a position of a height sufficient to hold the welt yarn on the back side of the knitting needle, and the next knitting operation is performed. Wells characterized by migration A second method of knitting a yarn is characterized in that in a knitting machine having a bed having two or more front and back beds, the welt yarn is held by two or more knitting needles facing each other on at least two beds. The third method is to knit the welt yarn. The third method is to weft-insert the weft-inserting yarn into the rubber knitting by the above-described welt-knitting method, and then knit the rubber knitting in the same direction as the weft-feeding yarn. A fourth method is a knitting method for weft-insertion knitting of rubber, which is characterized in that when a knitting machine having a bed having two or more front and back beds, the opposite needles are empty needles. After knitting, transfer the loop held by the knitting needle of the bed in one direction to the knitting needle of the opposite empty needle of the bed on the opposite side, and then insert the weft-inserting yarn by the above-mentioned welt yarn knitting method. The direction of the yarn feeder of the weft insertion yarn And transferred sequentially eye in one direction, a weft insertion knitting method of knitting, which comprises carrying out the re-organization from the back of the loop for the first time the organization of state.

The present invention will be described in detail below based on the following examples.

[0007]

[Embodiment 1] When forming a welt loop, in order to prevent the welt yarn from rising from the sinker portion of the knitting machine, the welt yarn is pressed by the back (lower) side of the knitting needle as shown in FIGS. .. The timing of raising the knitting needle in order to hold the welt yarn on the back side of the knitting needle is as follows: when the knitting needle rises, the weft yarn reaches too far below the knitting needle as shown in FIG. Yes, FIG. 3 shows the state.

FIG. 4 shows a pattern of needle operation for producing knit and tuck loops following welt yarn knitting.
1 shows an example of a conventional method (upper side) and a method of the present invention (lower side). Since the knitting needle operation of the conventional knit and tuck loop using the cam is started from the position A shown in the upper diagram of FIG. 4, sufficient welt holding cannot be performed. On the other hand, in the method of the present invention shown in the lower diagram, the knitting needle can be raised to the position B in FIG. 4 and knitting can be started from this position, so that the welt yarn can be sufficiently pressed. ..

Similarly, FIG. 5 shows an example of a needle operation pattern for performing a transfer operation following the welt yarn knitting. Since the transfer needle operation of the conventional method is started from the position shown in FIG. 5A on the upper side, sufficient welt holding cannot be performed. In the present invention, the knitting needle can be raised to the position shown in Fig. B on the lower side of Fig. 5, and the transfer operation can be started from this position, so that the welt yarn can be sufficiently pressed.

More specifically, n-1 at the time of specific welt formation,
Table 1 shows the welt loop organization table for n and n + 1 courses.
The position of the knitting needle after knitting the n-course corresponding to this knitting table is shown in FIG. 8, and the obtained stitches are shown in FIG. Therefore, according to the present invention, the welt thread does not float above the sinker portion as compared with the conventional method using the cam, and the welt loop can be continuously formed.

The method for forming a welt loop with a knitting needle having two or more beds is basically the same as the above method. The knitting table of the welt loop at the time of forming the welt in that case is shown in Table 2, and the positions of the knitting needles of the n-course knitting table corresponding to this knitting table are shown in FIG.

[0012]

[Embodiment 2] In order to insert the welt yarn into the rubber knitted fabric, the knitted fabric as shown in FIG. 6 can be knitted by repeating "rubber knitting → welt knitting → rubber knitting". Pressing of the welt yarn during knitting of the welt yarn is performed using a knitting needle holding a loop as shown in the first embodiment.

Regarding rubber knitting after welt yarn knitting,
The knitting needle used to hold down the welt yarn has the knitting operation pattern as in the first embodiment (see FIGS. 4 and 5).
The rubber knitting can be performed with the other knitting needles and the other knitting needles can be knitted with the normal knitting operation pattern. Table 3 shows a knitting table of the welt loop at the time of forming a welt in this case, and FIG. 11 shows the positions of the knitting needles corresponding to the knitting after the n-course knitting.

[0014]

[Embodiment 3] Knitting when the opposing needles are empty needles (Tenji or 1
As an example of inserting a welt yarn in (1 × rubber, etc.), the knitted fabric of the front surface knitted fabric as shown in FIG. 7 is obtained by repeating "front surface knitted knit → transfer 1 → welt knit → transfer 2 → front knitted knitting". A knitted fabric in which a welt yarn is inserted can be knitted.

In order to express it more specifically, n-1, n,
Table 4 shows the composition table of the n + 1 course. As shown in FIG. 12, after finishing the n-1 course front knitting, in the next n course welt knitting, the welt loop to be knitted is n-1
A knit loop desired to be positioned on the surface rather than the knit loop knitted on the course is transferred to the knitting needle of the opposing empty needle by using the conventional transfer needle operation pattern (see FIG. 5).

The pressing of the welt yarn in the next n-course welt knitting is performed using the knitting needle holding the loop as shown in the first embodiment. This operation is shown in FIG. Regarding the transfer operation (transfer 2) after welt knitting,
The transfer needle operation pattern of the present invention in which the knit loop transferred after the n-1 course knitting is shown in Example 1 (see FIG. 5).
Using. The position of the knitting needle after the completion of this transfer operation is shown in FIG.

Next, for the knitting of the front surface knitting on the n + 1 course, the knitting needle rising to hold down the welt yarn has the knitting motion pattern of the present invention shown in Example 1 (FIG. 4).
Knit knitting is performed according to the conventional knitting operation pattern (see FIG. 4).

[0018]

EFFECTS OF THE INVENTION In order to knit a knitted fabric which has a woven property even though it is a knit product conventionally called an inlay, it is not possible to knit it only by a welt operation, but a tuck operation is used. Was common. However, according to the present invention, since the inlay can be knitted over the entire range of the knitting machine bed or partially continuously without using the tuck operation, it is possible to knit a fabric having a property closer to that of a woven fabric.

Further, by utilizing this continuous welt knitting, the yarn supply which is no longer needed during the knitting can be evacuated from the knitting range, or the retracted yarn supply can be moved to the knitting range without hindering the knitting range. Therefore, the efficiency of knitting of the knitted fabric is improved. If it is used for the welt of the back tissue with a single jacquard, the back tissue can be knitted continuously for 5-6 needles or more without knitting the stitches, so the conventional welt for the back tissue is 5-6 stitches or more continuously. There are no restrictions on knitted fabric design that arise from being unable to knit.
