The present invention has a stretchable weaving yarn that does not knit knitting, so that it is possible to walk the waveform between the knitted fabric of the tissue. It is about.

Korean Utility Model Publication No. 84-32, known as a pile knitting machine for reducing elasticity, was to improve the conventional seal knitting machine consisting of a dial cam and a cylinder cam to prevent the elasticity by welting the paper tissue at one interval. This could not be expected to prevent complete stretch due to unwelded paper.

In addition, Utility Model Registration No. 17,287 (Utility Bulletin 79-1694), which is a preliminary draft of this planner, was merely a circular knitting machine for double-sided file knitting, and it was not possible to organize a double-sided file letter for preventing elasticity.

This design is an improvement of utility model registration No. 17,287. It uses a long, short knitting needle and a special sinker, and a stretch preventing weft is knitted by a cam device to hang the stretch weft on the front and back of the floor. It is an object of the present invention to provide a pile letter capable of restraining the elasticity of the pile letter to the maximum by covering the waveform in the coarse direction and the alternating direction without this.

Referring to the present invention in detail by the accompanying drawings as follows.

Two types of eccentricity, hyphen needle (HN) (hereinafter referred to as long needle) and needle needle (LN) (hereinafter referred to as short needle) as shown in FIG. 1, are alternately inserted into the acupuncture needle. 2 is a sinker (S) used in the present invention, which is a lower nose (bottom nose) S ₁ , a lower throat (bottomthroat) (S ₂ ), a middle nose (S ₃ ), a middle throat (S ₄ ) It consists of an upper nose (S ₅ ) and an upper draft (S ₆ ).

3 shows the sinker cam C ₁ (upper curve) and the single needle cam pole C ₂ (lower curve) used in the present invention. The sinker cam C ₁ is a conventional one, and the _single needle cam (C ₁ ). ₂ ), cam group A, → cam group B → cam group A '→ cam group B → cam group A were combined in this order.

Cam group B is composed of a normal double-sided pile knitting cam, cam group A is a short needle rising cam (1) and (2) and a short needle lowering cam (3), long, short needle rising cam (4), long, short needle lowering cam ( 5), and the cam group A 'is combined with the long needle ascending cams (6) and (7), the long needle descending cam (8), the bowels, the short needle ascending cams (9), and the long and short needle descending cams (10). .

The cam group A and the cam group A 'are substantially the same except that the former has a short needle rising cam 1 while the latter has a long needle rising cam 6. FIG. 3A is a cam position display corresponding to the knitting process shown in FIG. 4A.

Referring to the knitting operation of the present invention 3, 4 and 5 as follows.

After supplying the anti-expansion weft Q in FIG. 4 (a) and then lowering the short needle LN biting the anti-expansion weft Q in FIG. 4 (b), the sinker S moves forward. At this time, since the long needle (HN) is stopped, the stretch preventing weft (Q) that is not bitten by the long needle (HN) is pushed forward by the sinker (S).

In FIG. 4 (c), when both the long and short needles (HN) (LN) rise, the stretch preventing weft (Q) is placed in front of and behind the long and short needles (HN) and (LN) as shown in FIG. Staggered.

Hereinafter, the double-sided pile is knitted by the pile yarn P, the surface pile yarn P _{1 and the} pile yarn P ₂ supplied in the process of FIGS. 4 (d) through 4 (g). It knocks over the guruup in the positioned state so that it is staggered across the bottom tissue in an unorganized state (see FIG. 6, first coarse).

Next, as in Fig. 4 (a) and Fig. 4 (b), the long hand (HN) comes down with the elastic prevention weft (Q) at (a ') (b) in Fig. When both (HN) and (LN) rise (Fig. 4 (c)), the stretch preventing weft (Q) is in a state opposite to that of the first coarse (HN) as shown in the second coarse of FIG. (LN) staggered in the stapling, so in the end, as shown in FIG.

In the present invention, the upper throat S ₆ of the sinker S serves to hold and push the anti-stretch weft Q. Letters knitted by the present invention is almost stretched in the width direction because the stretch preventing weft (Q) is almost straight in the coarse direction of the letter after processing.

Claims (1)

A normal double-sided pile knitting cam group (B) using a sinker (S) and a long needle (HN) (LN) in which an upper nose (S ₅ ) and an upper draft (S ₆ ) are formed on a conventional sinker. Knitting device of elastic double-sided pile letter made by combining cam group (A) and cam group (A '), which alternately crosses the weft prevention weft yarn (Q) to the long and short hands before and after.
