Description

DETAILED DESCRIPTION OF THE INVENTION The first object of the present invention is to sew interlocking elements made of synthetic resin or metal onto a slide fastener stringer tape made of synthetic fibers or blended fibers of natural fibers and chemical fibers. A pair of slide fastener stringers (hereinafter simply referred to as stringers) fixed by planting etc.
During secondary processing such as sewing, a slide fastener continuous chain (hereinafter simply referred to as "continuous chain") in which the slide fasteners are meshed together can be separated in a specified manner with bare hands without using any special equipment such as scissors or cutting cutters. It can be easily separated and used by tearing off the parts, and during the production process of continuous chains, transportation, packaging for sales, etc., they may break during handling and damage the product value, or The purpose of the present invention is to obtain a separating section of a continuous chain that has an appropriate strength without causing a decrease in production efficiency.To achieve this objective, the present invention uses a melting device such as an electric heating edge or an electric heating roll in the separating section of a continuous chain. It is characterized by a configuration in which a separation section consisting of multiple rows of separation holes is installed in the space of the chain perpendicular to the longitudinal direction of the continuous chain using a burn-off device, an ultrasonic synthetic resin melting device, a mechanical punching device, etc. .

Next, the second object of the present invention is to achieve the above-mentioned first object and also to solve the so-called so-called problem that occurs when a woven or knitted continuous chain tape is not cut properly at the separation section when the tearing operation is performed. In order to prevent the stringing phenomenon, when installing the separating section to achieve the above first objective, the relationship between the structures of the continuous chain tape has been fully considered, and separation holes are formed in the continuous chain tape to prevent the stringing phenomenon. The continuous chain tape is characterized by being arranged so as to encompass all of the warp yarns in the structure of the continuous chain tape.

Embodiments of the present invention will be described below with reference to the drawings attached to the specification. It goes without saying that all the technical ideas listed as essential constituent elements belong to the technical scope of the present invention, even if their embodiments are different from those described in this specification.

Example 1 In FIG. 1, 1 is a continuous chain tape woven or knitted with chemical fibers or blended fibers of natural fibers and chemical fibers, and 2 is a synthetic resin mesh sewn to the continuous chain tape with sewing thread 3. Separation elements or planted synthetic resin or metal fittings, A
5 is a continuous slide fastener chain in which a pair of stringers B and C are meshed through a meshing portion 4 (hereinafter simply referred to as a continuous chain); The removed space portion D is the separation portion of the present invention, and 7 is perforated perpendicularly to the longitudinal direction of the continuous chain of the space portion 5 using an electric heating edge, an ultrasonic synthetic resin melting device, a mechanical punching device, etc. Short separation holes penetrating from the upper surface to the lower surface of the installed continuous chain tape are arranged in double rows intermittently in the form of perforations at intervals. E is the space of the continuous chain created between the continuous stringer tapes from which the meshing elements have been removed by space processing. As shown in Fig. 1c, the separation hole 7 has a dish-shaped cross section with the upper surface having a slightly wider hole width than the lower surface. Continuous chain tape (hereinafter simply referred to as tape) is the shape that is easiest to process when localized heat melting is performed using the head of an ultrasonic synthetic resin melting device (the principle is the same as the well-known ultrasonic synthetic resin bonding machine). (Sometimes abbreviated)) The resistance or tearability when tearing at the separation part D differs depending on the material and structure, so it is best to choose an appropriate shape according to the properties of each material, and in the case of mechanical punching, the upper and lower widths are the same. In the present invention, since the separating portion D is continuously provided in the width direction of the tape including the space portion where the space has been processed, it does not matter whether the material of the element is resin or metal. In the embodiment shown in FIG. 1, the separation section D is composed of double rows XYZ orthogonal to the longitudinal direction of the continuous chain of space sections 5, and each row has long separation holes 7 arranged in a broken line and a white background in the broken line. Part 1 of the short tape fabric corresponding to the part
0's are arranged alternately. Therefore, since the connecting portions between the separation holes 7 in the same row are each made of raw material 10 of the tape, it has strong strength, so if you try to tear off such an arrangement in a single row, the specifications The stringing phenomenon that was first pointed out occurs with high frequency. Therefore, in this embodiment, the separation holes 7, which are longer than the adjacent single-row broken-line short fabric portions 10, are arranged in a staggered manner, and each separation hole 7 in a certain row is arranged in a staggered manner so that each separation hole 7 in the adjacent row is longer than the short fabric portion 10 in the adjacent row. The remaining portion 10 is placed in parallel across its entire length,
Even if the threads of the short fabric portion 10 are pulled strongly by the force of tearing, the tensile force acts on the long separation holes 7 in the adjacent row and becomes the breaking force of the separation holes 7. No tensile force is applied to the portion of the thread on the opposite side of the separation hole 7. The relationship between the weave structure of the tape and the arrangement of double rows of separation holes is shown in Figure 1 (b), which is an enlarged view of part A' in Figure 1 (a). The warp is a double row of separation holes 7 that are provided parallel to the width of the tape in the vertical direction in the figure, that is, the weft, and due to the staggered arrangement, the warp has a double row of separation holes 7 in the width direction of the tape. Since the thread is completely covered over its entire length by the thread 7, there is no fear that the thread will be pulled at the separation part D during the tearing and separation operation, thereby causing a string-pulling phenomenon. In this example, a woven tape has been described, but the same applies to a knitted tape. In addition, as shown in FIG. 1d, a separation part D is formed at a shallow depth 15 by melting the entire raw portion of the tape between the plurality of rows surrounded by the plurality of separation holes 7. If this is done, the possibility that the separation will spread to areas other than the separation part D of the tape fabric during the tearing operation will be further reduced, and the occurrence of stringing phenomenon can be prevented.

Embodiment 2 In FIG. 2, the separation part D is composed of double rows of X and Y, and in each row, the separation holes are long separation holes 7 corresponding to the long dashed line and short separation holes 7 corresponding to the long dashed line. The holes 8 are alternately arranged intermittently through the raw portion 10 of the tape. The arrangement of the separation holes in the parallel X and Y rows is such that each long separation hole 7 is located in parallel with each short separation hole 8 in the adjacent row and each portion 10 of the tape that remains as a fabric. In addition, the length of the long separation hole 7 exceeds the length of the short separation hole 8 plus the length of each portion 10 of the tape before and after the short separation hole 8, and the length of the long separation hole 8 and the tape It is arranged at a length and position to completely cover the intact portion 10 of the fabric in a parallel manner. Therefore, during the tearing operation, as in the first embodiment, it is possible to prevent the stringing phenomenon caused by failure to cut the tape.

Embodiment 3 In the embodiment shown in FIG. 3, the separation part D is composed of double rows XY or XYZ in a zigzag shape with different inclination directions every other row inclined in the width direction of the tape, and the separation holes 9 in each row are adjacent to each other. The tips 11 of the separation holes 9 in one row face the intermediate portions 12 of the separation holes 9 in the other row, and a portion 10 of the tape as a raw material is slightly present between the two. According to the arrangement described above, the part of the tape that remains between the separation holes 9 is narrower than in the above two embodiments, so when the tape is made of thick material, the tearing operation is suitable for performing on strong tapes. It has the same effect as the above two embodiments in that it can be made comfortable and at the same time prevent the stringy phenomenon. To explain the tearing action during separation, the zigzag separation holes 9 are arranged in a staggered manner, and one end 11 remains in the middle part 12 inside the other end 11 of the separation hole 9 with a small amount of tape fabric. Since they are in contact with each other through the portion 10 of the tape, when tearing force is applied, the tearing force is always applied to the narrow portion of the tape fabric between the opposing separation holes 9, and the separation spreads in a zigzag pattern. The stringy phenomenon does not occur because the

Embodiment 4 In the embodiment shown in FIG. 4, the separation part D has short tapered parts 13 on both sides of a linear separation hole row Y formed intermittently in the form of perforations and consisting of short separation holes 7 in the center. The tapered part 13 has a long separation hole 14 having a shape of )-shaped separation holes, the raw portion 10 of the tape sandwiched between each separation hole is made into a narrow, thick or strong tape in a manner different from that in Example 3. Similar to the third embodiment, if applied, the separation work becomes easier.

The structure and operation of the present invention have been explained in detail through the embodiments of the present invention in the first to fourth embodiments.According to the present invention, a separation portion D is provided in a continuous chain in which a slide fastener is spaced. At the time of tearing off the tape, in particular, the separation section of the present invention is sufficiently equipped with a structure to prevent the stringing phenomenon from occurring. The slide fastener continuous chain with space processing D has the possibility of being accidentally cut at the separation part D during handling at each processing stage, transportation stage, division, packaging process, etc., causing problems in processing, transportation, and packaging. It also has excellent effects that do not reduce product value, so it improves efficiency during sewing processing in the manufacturing process of continuous chains and in various fields of use after shipment, contributes to automatic processing, and makes it easier to sell as single items. , it becomes easy to divide a long item.
