JP4501897B2 - Sewing structure of hem and seam allowance - Google Patents

Description

  The present invention relates to a sewing structure for clothing hem or seam allowance, particularly that of summer clothing.

  As the global warming phenomenon progresses, it has been screamed to save energy by simplifying summer clothing. For example, the back of the back part of the suit is removed, so that the entire lining is eliminated. Summer clothing that can be cooler is now on the market.

  Under such circumstances, in the conventional structure in which the hem and the seam allowance are sewn, the edge of the fabric is easily frayed and there is a problem in strength, and there is a problem in fashionability due to large piping.

  Prior to the examination of the present invention, the present applicant investigated prior art information and found Patent Document 1 to be a hit.

Registered Utility Model No. 2516216 (Scope of Claim for Utility Model Registration)

  In the scope of claim for registering the utility model of the above prior art, claim 1 is “a structure in which a seam having kinks wraps a seam allowance with piping tape”, and claim 2 is “a projecting allowance from a piping seam to a bent end of the piping tape” In other words, as shown in FIG. 3, the piping tape 35 is bent at both edges and further folded into two folds 35 'along a line in the center length direction. Is press-stitched 36 over the end of the fabric 34.

  In the above-mentioned prior art, it is impossible to reliably stop the edge of the fabric, and in claim 2, “the protruding margin to the bent end of the piping tape is 0.5˜”, but in actual work, Even if it can be sewn formally with a small protruding margin, the edge of the fabric falls off together with the piping tape, so it is not suitable for actual use and is equivalent to the empty theory on the desk.

  In view of the above, it is an object of the present invention to provide a hem / sewing allowance sewing structure that reliably prevents fraying of the edge of the fabric and that is thin in piping and rich in fashion.

  In order to solve the above-mentioned problems, the present invention is directed to press and sew 16 by pressing the bias tape 15 folded in a double fold 15 'along the length of the edge of the fabric 14 at right angles to the length. The overlock sewing machine 18 is hung on the edge where the edge of the bias tape 15 and the cloth 14 overlap, and then the edge of the bias tape 15 and the cloth 14 over the overlock sewing machine 18 is folded to form the pipe 19. The press sewing machine 17 is hung across the fabric 14 on the front and back along the pipe 19 and the bias tape 15.

  According to the present invention configured as described above, fraying of the edge of the fabric can be reliably prevented, and the piping width can be minimized. Further, compared to the prior art using a bias tape whose edges are bent in advance, sewing becomes easier and the cost can be reduced. In particular, according to the present invention, there is no case where the edge of the fabric is frayed and the clothing itself is messed up.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a perspective view of a state in which a suit is unfolded. 21 is a front body, 22 is a back body, 23 is a hem, 24 is a seam allowance. Applies.

  Along the edge direction of the fabric 14, the pressing tape 16 is applied to the bias tape 15 that is folded in a double fold 15 ′ at right angles to the length direction (FIG. 1A).

  Next, the overlock sewing machine 18 is hung on the edge where the edge of the bias tape 15 and the edge of the fabric 14 overlap, and then the edge of the bias tape 15 and the fabric 14 over which the overlock sewing machine 18 is hung is folded back to the pipe 19. Is formed (FIG. 1B).

  Next, the edge of the fabric 14 and the bias tape 15 to which the overlock sewing machine 18 is applied is folded back to form a pipe 19, and the press sewing machine 17 is applied to the fabric 14 and the bias tape 15 on the front and back sides along the pipe 19 (FIG. 1). (C)).

  FIG. 1C 'shows the reverse side of the hem / sewing allowance sewing structure completed as described above.

  As described above, according to the present invention, fraying of the edge of the fabric can be reliably prevented, and the piping width can be minimized. Further, it is not necessary to use a special bias tape, and the cost can be reduced. In particular, according to the present invention, the edge of the fabric is frayed so that the garment itself is not messed up, and the user can wear it with peace of mind and the industrial utility value is extremely high.

Claims (1)

  Along the edge direction of the fabric (14), the bias tape (15) folded in half (15 ') at right angles to the length direction is applied and pressed and sewn (16), and the bias An overlock sewing machine (18) is hung on the edge of the portion where the edge of the tape (15) and the cloth (14) overlap, and then the bias tape (15) and the fabric (14) with the overlock sewing machine (18) applied. A hem / sewing allowance sewing structure in which a pipe (19) is formed by folding the edge of the hem, and a presser sewing machine (17) is hung across the fabric (14) on the front and back and the bias tape (15) along the pipe (19). .
