Description

TECHNICAL FIELD The present invention relates to a braiding method in a torsion lace machine.

[Conventional technology]

Conventionally, in a torsion lace machine, it has been used as a lace for various clothing, a table cloth, and various other decorative fabrics.
As for the form, a flat cloth-like material formed by thread removing or the like and a cylindrical material without thread removing are produced.
On the other hand, as is well known in a torsion lace machine, a braided yarn is collected and wound around the center of the machine frame from a bobbin that is fitted on a spindle shaft that is erected on a spindle plate arranged on the circumference. While taking, the rotation of the spindle plate is controlled, and the adjacent bobbins are exchanged for each desired braid row, whereby the combined braid yarns are braided while being separated by a knife. Braiding of fabrics and cylindrical fabrics can sometimes be done without problems.

[Problems to be solved by the invention]

However, in the conventional case where the obi sashing is manually made, it is only possible to manufacture one or a few pieces per person per day in the case of a double bag cloth with tight eyes. . Also, when formed by a conventional machine braiding method such as the above-mentioned braiding method, it is not possible to make a sufficiently tight and stiff one, and a flat bag in which a pattern pattern is formed by replacing the braid threads on the opposite sides. Braiding as a fabric was impossible.

The present inventor has solved the above drawbacks and can be efficiently braided by using a conventional torsion lace machine. The flat bag fabric has a pattern appearing at an appropriate position, and the fabric having tight eyes is braided. It is intended to provide a possible method.

[Means for solving problems]

As the braiding method of the present invention, the winding bobbins arranged in parallel on the circumference are divided into at least two braiding groups having different thread colors and / or thread types, and the braiding threads supplied from each group are not combined but independent. Braided into a double flat fabric,
A flat bag fabric is formed by binding and braiding only both ends of the front and back fabrics, and the two sets of braided yarns are instantaneously replaced at appropriate positions to form braids as constituent yarns of fabrics on opposite sides to form a pattern. It was done.

〔Example〕

An embodiment of the braiding method of the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view schematically showing a part of a main part of a braid of a torsion lace machine obtained by carrying out the braiding method of the present invention, and 10 is a spindle plate arranged in parallel on the circumference. , 11 are spindle shafts, 12 is a bobbin bobbin, and the bobbin bobbin 12 is fitted on the spindle shaft 11 which is erected on the spindle plate 10, and the braided yarn 13 wound on the bobbin bobbin 12 is provided with a yarn feeder 14 The yarn is collected from the machine frame central portion 15. Numerals 16 and 17 are knives divided into odd rows and even rows. By rotating the even and odd portions of the spindle plate 10 alternately by 180 °, the adjacent spindle shafts 11 and 1
1, the positions of the braided yarns 1 are interchanged, the braided yarns 13 and 13 fed from the bobbin bobbin 12 are also combined, and the knives 16 and 17 act alternately on the combined braided yarns to take up the winding rollers 18, 19 and 20. The dough 21 is wound up.

Next, the braiding method of the present invention will be described based on the braided organization chart shown in FIG.

The symbols ○, △, and □ in the figure are the spindle plates 1 respectively.
0 indicates the type of yarn wound around the bobbin 12 that is fitted on the spindle shaft 11 that is erected upright, and the ∘ mark indicates the braided yarn that constitutes one side of the flat fabric, and the Δ mark indicates Is a braided yarn which also constitutes the other surface, and the yarn marked with a circle and the yarn marked with a triangle are different types and / or different colors. Also, the square marks are core yarns inserted in the braiding direction in both edge portions. Further, a cross mark indicates a position where the spindle shaft 11 is not erected, that is, where the braided yarn is not arranged.

Here, in this embodiment, a torsion race machine using 96 spindles (spindle shaft) is used, but the one actually used for the main knitting is 77 spindles, which has a range shown by S in FIG. The spindle plate 10 is used, and the total number of knives is 48, which is half of that of a race machine having a normal number of spindles. Therefore, the number of even rows and the number of odd rows are 24 each. Only the knife corresponding to the above-mentioned working range S will be involved in the braiding. Although only a part of the bobbin and the braided yarn are shown in the drawing for simplification of the drawing, actually, the necessary number of yarns are provided in the operation range S. Two
Reference numeral 2 denotes a bush, which is fitted into a bush holder 23. The bush 22 has a rectangular opening 24 slightly forward of the center of the bush, and the braid unwound from each bobbin 12 is unwound. The thread 13 is penetrated in a tensioned state from below the opening 24 toward above. More knife 16,
The shape of the contour portion 25 at the working tip end when 17 is gathered in the machine frame central portion 15 is a non-circular shape corresponding to the shape of the bush 22, and in the embodiment, an elliptical shape that is long in the left-right direction of the race machine. As a result, the tightness of the braided yarns combined with each other is improved, and the appearance of the braided product is beautiful.

Therefore, the braided yarn divided into two braid groups is
Marked and marked with a braided yarn ○ and a braided yarn that are fed
In one cycle R of the spindle plate, the front side fabric is braided by the braided yarn Δ and the back side fabric is braided by the braided yarn ○ without crossing each other except for the outer edges. At both edges, a part of the braided yarn ◯ and a part of the braided yarn Δ are combined and knitted and braided to form a flat bag material as a whole. The braided yarn mouth is inserted in the longitudinal direction in the bag material near both edges, but this yarn does not necessarily have to be inserted, and the use may be selected depending on the type of the braided yarn to be used.

When the pattern is to be formed, the braided yarn ○ and the braided yarn Δ are moved adjacent to each other, for example, by operating the spindle plate 11 at a position C in the drawing so as to switch the mutual positions. Can be replaced with each other so that they can be braided as constituent yarns of fabrics on opposite sides. As a result, the different or different colored patterns 26 are formed on the front and back sides by replacing the front and back braided yarns at the positions where the patterns are formed.

In the above examples, the number of braided yarns on the front and back sides is 25, but this can be achieved by increasing or decreasing the number of yarns to be used depending on the width of the fabric. The spool bobbins may be operated so that they are braided independently of each other.

〔The invention's effect〕

According to the braiding method of the present invention as described above, a product having the same appearance and quality as the band tightening conventionally manufactured by hand can be efficiently manufactured by one to several fibers per hour. It is a thing.
