摘要： A sewing machine includes a supporting plate portion and a needle. The supporting plate portion contacts sewing fabric that is moved in a predetermined direction during a sewing operation. The needle is vertically moved between a top dead center above the supporting plate portion and a bottom dead center below the supporting plate portion. The supporting plate portion has a needle hole through which the needle passes. The lower end opening of the needle hole is larger than the upper end opening.

摘要： A needle plate (5) for execution of overedging seams to be used in association with a device (1) has a main slot (21) and an auxiliary slot (22) formed at a primary side (17) of said needle plate and each designed to be passed through by a respective needle (3, 4) of the device (1). Also formed in the needle plate (5) at the primary side (17) thereof, is a main tab (23) and an auxiliary tab (24) which are such arranged that to each slot (21, 22) corresponds a tail portion (23b, 24b) of the respective tab (23, 24) by which the corresponding seam portion formed is discharged as the workpiece moves forward. The tabs (23, 24) have substantially aligned end edges (23a, 24a) along the primary side (17), whereas the slots (21, 22) are mutually offset transversely of the primary side (17).

摘要： An overlock stitch is formed by sewing machine (11 fig. 1) into a work product (34) and the work product is accelerated away from the sewing machine so as to stretch the thread chain (Fig. 5). The stretched thread chain is cut by cutter (40), and the leading thread chain (43) recoils back toward the hollow chaining tongue (21) and is drawn into the chaining tongue by the stream of air (26) created by vacuum canister (52 Fig. 6). The next work product draws the leading thread chain out of the hollow chaining tongue and the sewing machine captures the leading thread chain in the stitch. Transfer conveyor (15 Fig. 1) moves the work product (34) into alignment with everter tube assembly (106), grippers (109 and 110) grip and open one end of the work product (Figs. 9-14), and air drawn through the everter tube assembly everts the work product. The gripper tube assembly opens along its lower portion (Fig. 16) and drops the work product.

摘要： The present invention aims to avoid occurrence of a hitch stitch by using a simple construction and control. A presser foot device (21) includes a pressing member (22) that presses a sewing workpiece by moving up and down in synchronism with a sewing operation, and a guide member (23) provided at the lower end of the pressing member. The guide member has an opening section (29) provided to allow an upper thread to pass therethrough in a rotating direction of a rotary hook (3), and a restricting section (23a) provided to restrict movement of the upper thread in a direction opposite the rotating direction of the rotary hook. Upon determination that a direction in which a next stitch is to be formed belongs to a predetermined hitch-stitch forming area, detouring movement of a frame (5), holding the sewing workpiece, is carried out. This detouring movement includes moving the frame in such a direction in which the upper thread, extending downward from a sewing needle, moves out of the opening section of the guide member and then further moving the frame to a target position corresponding to the next stitch such that the upper thread, having moved out of the opening section, abuts against the restricting section.

摘要： A sewing machine that suppresses sewing defects is provided. The sewing machine includes: a sewing needle, held by a needle bar and moving back and forth while holding an upper thread; a shuttle, configured to hold a bobbin around which a lower thread is wound and which is housed in a bobbin case, and cooperating with the sewing needle to form a seam; a presser foot member, configured to press a to-be-sewn article at a sewing position directly below the sewing needle; a feeding mechanism, feeding the to-be-sewn article from the sewing position to a first direction; a needle drive portion, provided separately from a belt drive portion to synchronously move the sewing needle and the presser foot component in the first direction; and a control portion, which controls so that the needle drive portion and the belt drive portion operate independently.

摘要： A needle plate base in a multi-thread chain stitch sewing machine with a seam ravel preventing apparatus is divided into a left needle plate base for attaching a needle plate thereto and supporting a swinging support shaft of a thread hanging hook; and a right needle plate base for fixedly supporting a stopper member and a thread handling air cylinder and a stopper air cylinder. The right needle plate base is fastened to a sewing machine bed. The left needle plate base is fastenably and unfastenably fastened to an upper surface of the bed via screw members. Adjustment of stitch performation, and maintenance, e.g., replacement of various kinds of components stored inside the bed, can extremely easily and simply be carried out without having much trouble and requiring labor and time, and therefore, the stitch performation and predetermined ravel preventing function can be constantly surely reproduced.
