摘要： PROBLEM TO BE SOLVED: To ensure to permit label sewing even in the case when the set speed of a sewing machine is too low. SOLUTION: In a single thread loop stitch buttoning sewing machine provided with a selecting means selecting an optional sewing form from a plurality of sewing forms including at least button sewing and label sewing, a performed sewing speed is set at a limited speed guaranteeing the penetrating force to a label or higher at the time of label sewing. For example, the maximum speed and the limited speed that are set are read (Steps S1, S6), and the performed sewing speed is set at the limited speed (Steps S7, S8) in the case when the set maximum speed is lower than the limited speed. The performed sewing speed is set at the set sewing speed or the maximum speed (Steps S7, S9 to S11) in the case when the maximum speed is the limited speed or higher.

摘要： PURPOSE: To smoothly take out a sewn object after the end of sewing at the time of performing chain stitch not to form idle chain stitch in the state of no object to be sewn by providing a member absorbing the sag of a needle thread operating only when the sewing machine is reversely rotated from near a bottom dead center of a needle bar. CONSTITUTION: When taking out the sewn object after the end of sewing in the case of performing chain stitch not to form idle chain stitch in the state of no object to be sewn, this sewing machine is stopped in the state of turning a needle bar to a bottom dead center position and then rotated backward. Then, since thrust torque is always applied to a thread bringing-up arm 4 by a wavy clip plate 7, the thread bringing-up arm 4 is turned backward in an arrow direction together with the backward rotations of a driving shaft 3. On the other hand, the amount of a needle thread 1 to be supplied is made maximum at the bottom dead center position of the needle bar and a needle thread loop is almost formed by the sag of the needle thread 1, for which the amount to be supplied is made maximum, between a needle hole and the sewn object because of the elevation of the needle bar. However, a probe 4a elevated by the turn of the thread bring-up arm 4 catches and brings up the needle thread 1, the sag is absorbed and the state of forming no needle thread loop is kept.

摘要： PURPOSE:To reduce the number of assembling steps and manufacturing cost by eliminating a complicated power transmission mechanism for controlling rotation of a looper and eliminate a mechanical element such as a support bearing of a looper or a driving gear. CONSTITUTION:In a looper device 6 which is disposed below a sang needle 1 driven vertically and reciprocatingly in a chain stitching sewing machine, a motor 7 for controlling the device 6 is disposed so that a motor axis 8 is approximately in axial alignment with the axis of the needle 1, and a thread pass hole is drilled through between the opposite ends of the axis 8, and a thread outlet port at the upper part of the thread pass hole is offset from the center of the axis 8 and a clearance part is provided at the upper part of the axis 8 to allow the needle l to descend downwardly from the thread outlet port.

摘要： PURPOSE:To obtain loopers of a chain stitch machine, which obviates the need to bend thread holes of the loopers to simplify the production process, and makes the sewing thread handling work easy to improve the working efficiency in addition to reduce the production cost. CONSTITUTION:Sewing needle 1 of a chain stitch machine is vertically reciprocated and loopers 6, 20 and 30 arranged under the sewing needle 1 consist of base blocks 7, 21 and 31 which are rotated about the extended axial line of the sewing needle 1. The base blocks 7, 21 and 31 have thread holes 9, 23 and 32 with no bent parts at positions eccentric to the rotation centers of the base blocks 7, 21 and 31 and sewing needle escaping parts 10, 24 and 33 on the upsides, so that the sewing needle 1 can descend from the upper openings of the thread holes 9, 23 and 32 down to the lower parts through the sewing needle escaping parts 10, 24 and 33.

摘要： PURPOSE:To easily tie a loose end of a thread to cloth in a process after conducting chain sewing on the cloth, by pulling up the thread using a crochet hook in the last stitch on the cloth and cutting the thread so that a large length of the thread remains loose after the last stitch. CONSTITUTION:For cutting a thread 36' when the last stitch 41 is completed in chain sewing 36b using the thread 36', the thread 36' is pulled up above cloth 35 by means of a crochet hook 9 of a crochet needle 8. In this case, a length L3 defined as a length of a portion of the thread 36' between an end 43 thereof on the side of a previous stitch 42 and a portion 44 thereof passing through a pinhole 4 in a bed via the crochet hook 9 is larger than a length L4 defined as a length of a portion of the thread 36' between an end thereof on the side of a previous stitch and a portion thereof passing through the pinhole 4 in the bed via the crochet hook 9 during the chain sewing process. In this condition, the thread 36' is cut at a position between the pinhole 4 and a looper 12' by.

摘要： PURPOSE:To so stitch as not to clamp a laminated base material without cutting even when the material is stitched by a stitching yarn of very brittle fiber having low elongation like a carbon fiber yarn or a glass fiber yarn. CONSTITUTION:A method for stitching a laminated base material 1 while sequentially forming interstices by a reciprocating needle 3 comprises the steps of drawing a stitching yarn 2 of a length corresponding to a prescribed interstice by the needle 3, then moving the needle 3 in a direction of the material, moving the base material 1 until an end of the needle 3 arrives at the material 1, and sequentially stitching while forming the interstices.
