Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing the cut end of a double-stripe cord having a double-stripe section that thins the fibers and protects the core wire.

In conventional bag-cutting cords, as shown in Figure 1, the fibers at the cut ends are generally folded back inside the bag and tied with cotton thread or the like to prevent the fibers from coming loose. However, it has the disadvantage that it requires skill and takes a long time.

The present invention has been made in view of the above drawbacks, and will be described below with reference to the embodiments shown in FIGS. 2 and 3.

FIG. 2 shows the state of the double-shot cord before terminal processing, and FIG. 3 shows the state of the double-shot cord after terminal processing.

In both figures, reference numerals 1 and 1 indicate a core wire consisting of a conducting wire la and an insulator lb covering the conducting wire la. 2 is a bag made of green fibers made of heat-shrinkable synthetic resin such as nylon;
(In the case of this embodiment, the bag portion 2 is constructed in two layers: an upper bag portion 2a and a lower bag portion 2b.) The core wires 1, 1 are stored and protected therein.

When the end portion 3 of the bag portion 2 in which the core wire 1 is exposed for a slightly longer length in the bag cord having the above structure is heat-shrinked as shown in FIG. 3, the fibers are prevented from coming loose and are tightly attached to the core wire. This prevents the bag portion 2 from moving. In addition, 4 and 4 in the figure are terminals fixed to the conducting wire la. As described above, the bag cord terminal processing method of the present invention heat-shrinks the bag portion of the cut end of the bag cord, which has a bag portion that protects the core wire by assembling fibers made of heat-shrinkable synthetic resin such as nylon. This feature prevents the fibers from coming loose and allows the bag portion to adhere tightly to the core wire, so it does not require any skill to terminal the bag cord.
And now it can be done quickly.

Claims (1)

[Claims] 1. Heat-shrinking the bag part at the cutting end of a bag cord, which has a bag part that protects the core wire by braiding fibers made of heat-shrinkable synthetic resin such as nylon, to prevent the fibers from coming loose and protect the bag part from the core wire. A method for processing a terminal of a double-stripe cord, characterized by bringing the terminal into close contact with the cord.
