2. Description of the Related Art In a cuff and a hem of a T-shirt, a part of a predetermined width is folded back from the peripheral edge of a sewing cloth in order to impart an appropriate aesthetic feeling and to enhance resistance to friction with a body or other cloth. Edge processing is performed to sew each other in a state of being overlapped with the back surface of the sewing material to form a cylindrical portion along the peripheral edge. Conventionally, the following two methods have been generally adopted for this kind of edge treatment.

The first method shown in FIG.
A part of a predetermined width is folded back from the side edge 50 of the sewing machine, superposed on the back surface of the sewing material 5 and fed onto the sewing bed of the sewing machine, and then, as indicated by the arrow in the figure, from the front side by the single or plural needles. Is a method of forming the tubular portion 51 by performing plain stitches (flat stitch, single chain stitch, double chain stitch, etc.), and the second method shown in FIG. 2 is similar to the first method. After folding, the sewn material 5 is folded back in the opposite direction with the side edge 50 overlapped on the back surface as a fold line, and between the side edge 50 and the sewn material 5 laminated in two layers below the side edge 50, This is a method in which overedging is performed as indicated by an arrow in the figure, and finally the folded-back portion is extended to obtain the tubular portion 51.

Each of these methods has contradictory drawbacks. In the first method, a flat finish can be obtained on both front and back surfaces, whereas in the second method, a finished finish is obtained. There is a problem that the narrow strip portion 52 required for overedging protrudes on the back surface of the sewing cloth 5 to deteriorate the wearing comfort. On the contrary, in the second method, the sewing cloth 5 after finishing is finished.
No seams appear on the surface of the sewing machine, whereas in the first method, the seams are unavoidable on the surface of the sewn fabric 5, which has the drawback of impairing aesthetics.

However, the difficulty in the first method, namely,
The quality of the aesthetics due to the appearance of the seams is based on the subjective judgment of the consumer, and by selecting the appropriate stitch type from among the various stitch types stipulated in JIS L 0120, some aesthetic Can be maintained. Figure 3
It is a detailed view of the seams when the two-needle flat stitches designated by the symbol 406 in JIS L 0120 are adopted. In this case, two seams 53 which are parallel to each other are formed on the surface of the sewing material 5.
Only 53 are arranged regularly, and the degree to which aesthetics are impaired is small. For these reasons, in Japan, products treated by the first method tend to be preferred to those treated by the second method, and the first method is exclusively used for the peripheral treatment of cuffs and hem. Has been adopted.
