Abstract

The present invention provides a seam-forming method for a sewing machine that can form firm seams without reversing the feed of cloth. The material to be sewn is fed pitch by pitch to form two independent seams one over the other by a sewing machine with a first shuttle rotated counterclockwise, a first needle, a second needle and a second shuttle rotated counterclockwise, arranged in this order in the feed direction of cloth. During each process of feeding the material, the needles simultaneously and independently form a line in order to forming twin lines of independently-made co-knotted stitches, in which one stitch includes perfect stitches, and the other stitch includes hitch stitches.

Description

V. Description of the invention In the sewing machine, the two needles D1 and D2 reciprocate at 7 o'clock each autumn, and are located in a counterclockwise direction = reverse 180. Take the shuttle hook C1 that rotates in the direction of universal movement, and use one shuttle hook C2 that rotates counterclockwise, where the two sewing materials are arranged in the sliding direction, and the feeding second = the order is formed. Hold so that the fabric is not slipped when the next stitch is formed. In operation, first, the cloth feeding amount of the needle D1 (that is, closer to the operator) and the needle D2 is considered by using a feeding amount setting device (not shown in the figure). The distance between the two places is set to adjust the feeding amount of the two places, so that the stitches are sewn at the corresponding positions accurately. When a sewing machine is sewn after the above-mentioned feed amount setting is completed, the stitches as shown in Fig. 5 are continuously sewn therefrom. The stitch will be described in detail in the last 0. That is to say, the stitch is made when the positional relationship between the two needles and the side two hooks are alternately switched between the two patterns. It is worth noting that when one of the lines goes online, that is, the line A 丨 is caught by the ^ hook C1 (closer to the operator), the line a 1 and the line b 1 are caught by the hook C 1 Make a full stitch p together, and at the same time, another upper thread, that is, when the upper thread A2 is hooked by the hook C2 (farther from the operator), the upper thread A2 and the lower thread B2 are connected by the hook C2. Making a crochet together When the fabric advances a pitch and the position of the needle is reversed, the upper thread A1 and the lower and thread B2 together make a crochet η through the hook C2, and the full needle P is just formed on the fabric In the same position.

Case No. 92107007 V. Description of the invention (13) At the same time, the position of each hook is adjusted by considering the amount of needle swing. After the remote sewing machine completes the above-mentioned adjustment operation, the stitch shown in FIG. 6 is thus continuously sewn from two lower threads ^ and 62 and one upper thread A:. This stitch will be detailed later. When the sewing machine is operated and the needle is out!), Lower it to the hook C1 (that is, a soil operator), the upper thread A and the lower thread β 1 are sewn together by the hook c 丨 = starting needle Η . Then, the needle D is raised above the fabric and swings in the feeding direction. After moving the iron D, the needle D is lowered again to sew with the lower thread β2 by the hook C2. A full needle P. Thereafter, when the cloth advances and slides a pitch, the needle D re-coating swings in a direction opposite to the feeding direction. The needle D is then lowered, / f lowers the thread B1-sewing-hook. In the next step, when the drop ^, the needle D is raised and swings in the feeding direction, and then the needle 0 is lowered again to sew a full stitch with the lower thread B2? . The above-mentioned continuous operation is repeated so that the full needle P and the crochet needle 11 are formed on each node. In the seam sewing as described above, one full stitch P and one crochet reed are formed on each of the two. In addition, when a single upper line is used to fix the cloth, the upper line of the three green cloths extends between adjacent nodes on the upper cloth, and the two lower lines extend between adjacent nodes on the lower cloth. In this way, the friction between the contact surface between the fabrics on the upper thread and the contact surface between the lower fabric and the lower fabric will be opened when the stitching is completed. In addition, the sewing speed of the sewing machine is slower than that of the rotary fan; that is, the feeding speed) is slower. However, the feeding direction is never reversed, and the second will feel no. Furthermore, the method of this embodiment can be reported only by modifying the traditional Z-shaped sewing machine, and according to this method / the direction of the needle and the hook opposite to each other is also perpendicular to the traditional sewing.
