摘要： Disclosed is a two-needle sewing machine that improves strength in a convex curve part by bringing a pair of stitches close together when sewing an item to be sewn that includes the convex curve part. A two-needle sewing machine 1 includes a bed part 3; a column part 5; an arm part 6; a needle shaft 11 that is disposed on the leading part of the arm part 6; two sewing needles 13, 14 that are attached to the needle shaft 11; two horizontal hooks 15, 16 that catch the respective needle thread loops of the two sewing needles 13, 14; and a conveyor member 21 that conveys a material to be sewn 40 in a direction approximately orthogonal to the bed part 3. On the two-needle sewing machine 1, the sewing needle 13, which is positioned in a location distant from the column part 5, is disposed closer to the conveyance side of the material to be sewn 40 than the sewing needle 14 that is positioned in a location closer to the column part 5.

摘要： A safety device is not required for avoiding a transition to a stitch forming state from a looper threading state during a gas supply operation of a gas supply pump, and a threading can be performed more easily with one-touch operation to a looper by one-handed operation of small number of times on the operation for being simplified on mechanism. An engaging clutch (60) for respectively transmitting power from a sewing machine motor (M) to a drive shaft (5) driving a stitch forming device including the looper at the time of the stitch formation or to the gas supply source (40) at the time of the looper threading comprises a structure which is moved to one of a gas supply drive member (61) which transmits the power to the gas supply source and a stitch forming drive member (64) which is fastened to one end of the drive shaft and transmits the power to the stitch forming device so that approach/separation becomes free depending on a manual operation of a looper threading/stitch forming changeover manual operating portion and transmits the power from the sewing machine motor through a clutch hollow shaft (22) and retains a connecting state when connecting to the gas supply drive member.

摘要： A method for preventing seam ravel of multi-thread chain stitches is provided. After normal sewing is terminated with a looper set in a forward movement state, a state in which a needle thread loop caught by the looper is subjected to position-holding at a position closer to a forward movement end of the looper than a descent position of a needle is maintained until the needle descends through the needle thread loop caught by the looper. Thereafter, the position-holding of the needle thread loop is released to permit a sewing action for at least one stitch, thereby allowing the needle thread loop to be self-looped with a needle thread held by the needle. This surely strongly prevents the seam ravel of multi-thread chain stitches formed by the single needle, irrespective of the dimension of tension applied to the needle thread and the looper thread.

摘要： A quilting machine (10) is provided having at least one set of single needle stitch forming elements. The stitch forming elements include a needle (36) and a looper (39) mounted on separate heads (35, 38) that are independently moveable on a bridge (30) transversely relative to the panel. The bridge (30) is longitudinally moved by a servo (32) and the heads (35, 38) are transversely moved on the bridge (30) by separate servos (43, 44). A controller (60) drives the servos to chain stitch patterns and differentially move the heads transversely to account for transverse needle deflection. The drives of the needle and looper are phased to compensate for longitudinal needle deflection. The controller may store empirically determined data and respond to control signals and/or sensors (81, 82) to determine or predict deflection and calculate needle deflection compensation.

摘要： The invention improves the quality of the double-thread stitch line by preventing it from unravelling from the end and also simplifies the construction and improves the productivity of the machine by the use of a simpler mechanism for the looper which executes rotary motion. The double-thread chain-stitch is formed and tightened with one turn of the machine's main shaft. The sewing machine in addition contains autonomous disc-shaped cam thread tighteners for the top and bottom threads, a lifter for the bottom thread which can oscillate about its own axis. The looper is mounted in such a way that it can execute rotary motion in the vertical plane parallel to the line of stitch and can execute two rotations for each cycle of movement of the needle and lifter. With the invention, a double-thread chain-stitch sewing machine can be made in three variants with flat, columnar and cylindrical platforms respectively.

摘要： In a looper thread control device for a double chainstitch sewing machine, the sewing needles are lowered securely into a thread triangle, even in the conditions of low thread tension and high speed operation, and with an elastic looper thread, without rib or skip stitch on the fabric. A looper thread support member 1 moves up and down in cooperation with sewing needles NL, NR near the left end of the looper L. The looper thread support member 1 falls into the triangle prior to fall of the sewing needles, and seizes the looper thread LT. The looper thread support member 1 keeps holding until the eyelet LE on the looper is moved to the right side of the looper thread support member 1, thereby pulling out the looper thread LT from the thread source, and then releases its holding.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a slack of needle threads which extendedly exist below needle thread eyelet by taking up the needle threads by the resiliency of a needle thread pulling-up spring when a plurality of needles are lowered and a needle thread take-up feeds the needle threads at during sewing with a fine stitch pitch; and to form double chain stitch seams having no skips.
SOLUTION: Since the needle thread take-up 46 includes the needle thread pulling-up spring 47 on which the needle threads which are pulled out from needle thread tensioning devices are thread-hung together with the needle thread take-up by a thread hanging point P, the needle thread take-up completes drawing-up of the needle threads at the thread hanging point P after needle thread loops of the respective needles 12A, 12B and 12C are seized by a looper 14. A sewing cloth is fed for one feed pitch as the needles are moved down and the needle thread take-up draws out the needle threads, while the needle threads are pulled up at the thread hanging point of the needle thread pulling-up spring 47 by the resiliency, and thus the occurrence of the slack of the needle threads below the needle thread eyelets 12D, 12E and 12F is prevented. The needles are moved into a triangle which is formed by the needle thread loops before feeding by one feed pitch and a looper thread, The looper is shed from the needle thread loops, and the needle threads connected to the needle thread loops from which the looper is shed are drawn up by the thread tensioning point of the needle thread take-up against the resiliency of the needle thread pulling-up spring.
