Description

  The present invention relates to a method of manufacturing a composite tape in which a narrow child tape is passed through a tape passing portion provided on the surface side of a main body tape so that the child tape is visible and hidden.

  For composite tapes used for decoration of various underwear and clothes such as brassiere and slip shoulder straps, the tape is threaded at appropriate intervals in the longitudinal direction on the surface side of the main body tape formed by looms and knitting machines. There is a type in which a child tape is visible and hidden on the surface side of the main body tape by passing a child tape having a width smaller than that of the main body tape through the tape passing portion (see, for example, Patent Document 1).

  When manufacturing a composite tape in which such a child tape is passed through the tape passing portion of the main body tape, the main body tape and the child tape are separately formed on a loom or a knitting machine, and the child tape is later attached to the tape passing portion of the main body tape. I try to pass it manually.

Japanese Utility Model Publication No. 60-136388

  The composite tape in which the above-described child tape is passed through the tape threading portion of the main body tape allows a child tape formed separately from the main body tape to be manually passed through the tape threading portion of the main body tape later, so that the manufacturing efficiency is improved. There is a problem that the manufacturing cost increases.

  Accordingly, an object of the present invention is to enable efficient and inexpensive production of a composite tape in which a child tape is passed through a tape threading portion of a main body tape.

  In order to solve the above-mentioned problems, the present invention provides a tape threading portion with a space in the longitudinal direction on the surface side of the main body tape, and a child tape narrower than the main body tape is passed through the tape threading portion. In the composite tape manufacturing method, the main body tape and the child tape are simultaneously knitted by warp knitting, and the knitted child tape is supplied to the surface side of the main tape to be knitted and supplied to the surface side. A method of knitting the tape threading portion of the main body tape so as to hold the child tape was adopted.

  That is, the main body tape and the child tape are each knitted simultaneously by warp knitting, and the knitted child tape is supplied to the surface side of the main tape to be knitted and the child tape supplied to the surface side is held. By knitting the tape threading part of the main body tape, the trouble of passing the child tape through the tape threading part later becomes unnecessary, and a composite tape in which the child tape is passed through the tape threading part of the main body tape can be manufactured efficiently and inexpensively. I did it.

  By knitting the main body tape and the child tape with the same warp knitting machine, the main tape and the child tape can be knitted with one warp knitting machine, and the knitting speeds of the main body tape and the child tape can be naturally synchronized.

  By knitting elastic yarn into the child tape, the child tape can be stretched to prevent slack in the supply path for supplying the knitted child tape to the surface side of the main body tape. In addition, when weaving elastic yarn into the main body tape, depending on the shrinkage allowance when the main body tape is knitted, the child tape also has a shrinkage allowance when it is knitted, and the sub tape along the surface side of the main body tape. Can be prevented from becoming excessively long with respect to the length of the main body tape.

  The method for producing a composite tape according to the present invention is such that the main body tape and the child tape are simultaneously knitted by warp knitting, and the knitted child tape is supplied to the surface side of the knitted main body tape, Since the tape threading part of the main body tape is knitted so as to hold the supplied child tape, it is not necessary to pass the child tape through the tape threading part later, and the child tape is passed through the tape threading part of the main body tape. This composite tape can be manufactured efficiently and inexpensively.

The schematic perspective view which shows the warp knitting machine which employ | adopted the manufacturing method of the composite tape which concerns on this invention The top view which expands and shows the composite tape manufactured with the warp knitting machine of FIG. The top view which shows the modification of the composite tape of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a warp knitting machine 11 that employs a method for producing a composite tape 1 according to the present invention. The warp knitting machine 11 manufactures a decorative composite tape 1, and the main body tape 2 and the child tape 3 of the composite tape 1 are supplied to positions separated in the width direction of the needle bed 12 of the warp knitting machine 11. The warp yarns 4a and 4b and the knitting yarns 5a and 5b are knitted simultaneously. The warp yarns 4a and the pendulum yarns 5a for the wide main body tape 2 are supplied more than the warp yarns 4b and the pendulum yarns 5b for the child tape 3 having a narrow width. In this embodiment, polyurethane elastic yarns 6a and 6b are also supplied along the warps 4a and 4b, and the main body tape 2 and the child tape 3 into which these are knitted are given stretchability.

  The knitted child tape 3 is sequentially wound around four winding bars 13 provided at the front lower part, the rear lower part, the rear upper part, and the front upper part in parallel with the needle bed 12. The main tape 2 is supplied to the position where it is knitted. Each winding bar 13 is provided with a guide rod 14 for guiding the position in the width direction of the child tape 3, and the child tape 3 wound around each winding bar 13 is arranged on the knitting position side of the main body tape 2 with these guide rods 14. The width is gradually adjusted, and is fed straight downward from the winding bar 13 at the top of the last front side to the surface side of the main body tape 2 to be knitted. On the surface side of the main body tape 2, a tape threading portion 2 a is knitted at intervals in the longitudinal direction so as to hold the child tape 3. The composite tape 1 through the tape 3 is manufactured.

  FIG. 2 shows an enlarged view of the manufactured composite tape 1. The main body tape 2 is warp knitted so as to have a symmetrical pattern, and a narrow width knitted by warp knitting on a tape threaded portion 2a knitted in pairs in the longitudinal direction on the surface side of the center portion. The child tape 3 is passed. The main body tape 2 may have a left-right asymmetric pattern.

  FIG. 3 shows a modification of the composite tape 1. This composite tape 1 is provided with two tape passing portions 2a of the main body tape 2 at intervals in the longitudinal direction at intervals in the longitudinal direction, and a total of two child tapes 3 one by one in these tape passing portions 2a. The point that is passed is different. In this way, when manufacturing the composite tape 1 in which the two child tapes 3 are passed through the tape passing portion 2a, the position in the width direction of the needle bed 12 for knitting each child tape 3 is knitted on the main body tape 2. They may be distributed on both sides of the position in the width direction, or may be distributed collectively on one side. The same applies when three or more child tapes 3 are passed.

  In the above-described embodiment, elastic yarns are knitted into both the main body tape and the child tape so as to have elasticity. However, the main body tape and the child tape may have no elasticity without knitting the elastic yarn. In the case where the elastic yarn is knitted into the main body tape, the elastic yarn may be knitted into the child tape so that the shrinkage allowance of the knitting of the both is adjusted to some extent. In addition, the ratio of the shrinkage allowance of both tapes does not necessarily need to be matched, and may be as long as the length of the child tape along the surface side of the main body tape is not excessively large. It is also possible to provide a design in which a margin of a little length is given to the child tape or the main body tape, and the tape to which the margin is given is bent between the tape passing portions.

  Further, in the above-described embodiment, two sets of tape passing portions of the main body tape are provided at intervals in the longitudinal direction. However, the intervals between the tape passing portions can be arbitrarily set, and the intervals in the longitudinal direction are increased. It is also possible to provide the tape threading portion by one set, three sets or more, or different sets in the longitudinal direction.

  Further, in the above-described embodiment, the knitted child tape is wound around four winding bars and supplied to the knitting position of the main body tape. However, the method of supplying the knitted child tape is limited to that of the embodiment. It is not necessary to use such a material as long as it can be supplied so that the child tape is not twisted or loosened.
