Eight steps are the steps of the sewing process and the winding step. The sewing step is in the knees, and the steps will be held by the buttons. The surface fastener and the reinforcing buckle are held in a horizontal or substantially horizontal position at a predetermined sewing position and the fabric is placed between the two buttons, and the two filaments are kept independent by Orthogonal horizontal two-dimensional square so that the buttonholes of the two buttons are sequentially placed at the needle drop position, and the two buttons are simultaneously sewn on the fabric; the stitching step of the stitching is performed after the stitching step, the two buttons are reversed In a vertical or substantially vertical posture, in order to avoid an obstacle at the end of the cloth at the end edge of the cloth as the obstacle at the end of the cloth, the end of the cloth is folded back toward the opposite side of the needle drop position, in this state, Perform button seams for horizontal or approximate horizontal posture Winding wound around the periphery of the winding wire junction seam line junction. When the above two steps are separately performed by the sewing machine dedicated to the sewing buckle and the seam sewing machine dedicated to the winding seam, it is necessary to use two (two types) special sewing machine, and therefore, in addition to the increase in equipment cost, Also, since the two 201215727 sewing machines are set up (collocated), it is necessary to ensure a wide sewing space, and not only that the sewing machine that has been used by the sewing buckle is sewn (4). The fabric is temporarily removed by the sewing machine dedicated to the sewing buckle, and it must be reinstalled on the side of the special sewing machine for the winding seam to perform the winding seam. Therefore, the problem lies in the inclusion of the winding knot. The seams (4) and (4) are extremely inefficient, and the clothes finished with the sewing buckles are not of good productivity. [Prior Art] 3 In the past, as disclosed in the Japanese Patent Publication No. 419 8 0 2 3, in the case of the above-mentioned two steps, the sewing step and the winding can be seamed.
