Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a cord having a core-existing portion and a core-existing portion , particularly, a descending string used for beads.

[0002]

2. Description of the Related Art As means for holding beads in a descent string of beads, a part having a core and a part not having a core are provided in the descent string to form a step at the boundary, and the beads are stopped by this. I am trying. However, in order to form the part where the core is inserted and the part where the core is not inserted in the descent string, first, the core is provided at the center and the periphery is knitted into 4 strokes, 8 strokes, 16 strokes, etc. At that point, the remaining core is cut and then knitted to form a coreless part and a cored part. In this way, it is troublesome because the core part must be cut each time during the knitting, and the down strings have to be made by hand one by one, which is time-consuming and easy to mass-produce. There wasn't.

[0003]

[Invention is to provide an object of the present invention is to improve the future of the drawbacks, string easily and continuously to having a portion part and the core of the cored does not turn on, yet so as to be able to make to economic The purpose is to do.

[0004]

According to the present invention, a cord with a core is used, and the front cover portion is moved to one side to remove the exposed core portion. It is stretched to its original state so that a string of a predetermined length can be continuously produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The figures show the case of manufacturing a descent string (2) of beads (1), and FIGS. 1 to 4 show the outline of the process. The down string (2) has a portion (5) where the core portion (4) is present in the front cover portion (3) and a portion (6) where the core portion is not present.
Have.

Taking the case where the core portion is acm and the core portion is not bcm, and n pieces of this cord are continuously manufactured, for example, first, (a + b) ncm cored cord body Prepare (7) (FIG. 1). At that time, at the end of the cord,
It is preferable to form knots (8) or fix the ends by bonding or the like so that the core does not move.

Next, the front cover portion (3) of the cord body is brought close to the knot (8) side. At this time, the loop (9) formed on the knot (8) is hung on the support rod and the other end of the cord body is pulled to bring it closer to work. In the structure shown in FIG. 2, the front cover portion (3) is moved to ancm until the core portion (4) appears bncm.

The exposed core portion bncm is cut and removed (FIG. 3). In the remaining gathered front cover (3),
Hold the position (10) acm from the other end, and stretch the front cover part on the other end side to the original state (the state before the front cover part is brought close),
Form a down cord with a core portion acm and a coreless portion bcm (Fig. 4).

[0009] Here, after the pressing position (10) is cut to form a single downward string, these operations are sequentially repeated from the string body (7) to continuously form n downward strings. . When the above string is formed of nylon, polyester or other synthetic resin, a single down string can be made by fusing the string with a hot wire, a hot blade, etc. It's a little bit hardened, so it's better to have a striped end. It is also possible to provide an adhesive on the end of the cord, or to preliminarily provide the cord with a thread having the performance of the adhesive.

When various kinds of cords having different lengths are formed, the length of the cord body, the pressing position, the amount of stretching, etc. are adjusted accordingly.

FIG. 5 and FIG. 6 show that a ball is attached to the lower end of the down string.
The case where (11) is provided is shown. A rod-shaped body (1
2) is made, and the lower end of the down string (2) is tightened by using the binding string (13) on the element body at predetermined intervals (FIG. 5).

When the central portion (14) between the binding cords is cut,
A ball ball (11) is formed at the lower end of the down string (FIG. 6). The beads (15) are retained by a step (16) formed at a boundary between a portion (5) containing the core (4) and a portion (6) not containing the core of the down string. In this way, the beads (1) are formed using the descending string (2) (FIG. 7).

The above string can also be used as a haori string, a decorative string, or the like.

[0014]

Industrial Applicability According to the present invention, it is possible to continuously and simply manufacture a cord having the core-inserted portion and the core-not-inserted portion configured as described above, and it is possible to mass-produce the cord efficiently and at low cost. it can.

Claims (2)

[Claims] 1. A organized around a core which has a length of about several straps may form, providing a cord having a table to be part formed by weaving or the like, the table to be part To one side, thereby removing the exposed core portion, holding the position of the predetermined length of the front cover portion and stretching the front cover portion to its original state, and the portion where the core portion exists and the core. A method for producing a cord, which comprises forming a portion where no portion exists and cutting a position of a predetermined length of the front cover portion to form a cord. 2.
