The present invention is directed to a machine for processing the end of strings such as shoelaces made of nylon, detron, or polypuroprene. Conventional shoelaces made of synthetic fiber yarn is knitted long and then cut into lengths suitable for the purpose to form a sleeve (sleeve) coated with a synthetic resin film in order to prevent the end of both ends of the laces in use.

However, this sleeve has no choice but to leave the end of the sleeve broken when this part is bent, squeezed or rubbed during use. There was a dismissal. In order to solve this problem, the present invention mechanically heat-compresses a part corresponding to a part to be cut before cutting it into a string having a length suitable for the purpose of use. Shaped to be suitable for use, such as then cut the middle of the crimped portion is designed to obtain a string that is not broken or damaged at both ends as described in detail according to the accompanying drawings as follows.

In the intermediate support frame 3 of the substrate 2 provided on the upper surface of the base 1, the heater 4 is embedded to the inner surface, and the upper presser 6 in which the semicircular molding jaw 5 is formed on the front lower side is fixed and fixed. And the heater 4 'is embedded to the inner surface, and a semicircular shaped jaw 5' is formed on the upper front side, and the lower end presser 6 'on which the upper end of the operation period 7 is adhered is attached to the rear end for movement. It was done.

Unexplained symbol "8,8 '" is a long knitting string suspension pin,

"9" is the separation pin of the processed string,

"10" is stepping,

"11" is a spring interlocking spring installed,

"12" is a thermostat.

In this way, the present invention is suspended between the two suspension pins (8) (8 ') and the heater (4) before cutting the bundle (a) of the long wound knitted with synthetic fiber yarn to a length suitable for the purpose (4 ') to supply power to the upper and lower presses (6, 6'), and then pull one strand to form the center of the string (a) corresponding to the part to be cut, forming the jaw of the lower press (6 '). (5 '), and stepping on the stepping step 10, the stepping step 10, the interlocking step 11 is lowered to advance the operating step (7), accordingly accordingly according to the lower presser 6 that the upper end of the operating step (7) is coalesced ') Pulls the string a in the state of FIG. 3 (a) and is advanced as shown in FIG. 3 (b) to form the forming jaw 5' of the upper presser 6 and the forming jaw 5 'of the lower presser 6'. ) Is bonded to the portion to be cut of the string (a) is heat-compression, and once the cut portion is heat-compressed, the stepping step 10 is released when the soup that was tensioned when the interlocking rod 11 downwards Since the interlocking rod 11 is raised to its original position by the contracting force of the ring, the operating rod 7 is reversed, and accordingly, the lower presser 6 'is reversed to the original state as shown in FIG. 3 (a).

In this way, the present invention, which is advanced by advancing the lower presser 6 'and joined with the upper presser 6, is heated and compressed between the forming jaws 5 and 5', according to the material of the string a and the presser 6 as necessary. If the heating temperature of (6 ') is properly adjusted by the temperature controller (12), and the pressing process of the part to be cut is repeated about 2-6 times to make it heat-compress, the heat treated part is melted or discolored more than necessary. Since it is processed in a suitable state without being closed, such as the end, the tip is not released or damaged even after long-term use, and the life is long, and the forming jaw (5) (5 ') of the up-and-down presser (6) (6') ) In the shape of semi-circle, reflection angle, etc., the cross-sectional shape of the part to be heat-compressed can be processed so as to be suitable for use, and is much better and better than that of a sleeve formed using a conventional synthetic resin film. Provide strap So the straps of shoes, of course, a very effective devised a string of pibokryu such as jumpers that can be suitably used in a wide range of applications.

Claims (1)

The heater 4 is embedded in the intermediate support frame 3 of the substrate installed in the substrate, and the upper presser 6 having the forming jaw 5 is fixed and fixed, and the heater 4 'is embedded, and the forming jaw 5' ) Is formed, the rear end of the end of the operation (7) is bonded to the lower pressing machine (6 ') of the end of the shoelaces of synthetic fiber yarn was welded to move freely.
