摘要： A needle thread guide device for double ring stitch sewing machine is used for the case that a double ring stitch is formed by forming a plurality of needle thread loops below a fabric and allowing a looper to successively enter these needle thread loops. The needle thread guide device has a cam (8c) which is formed at a location near a thread receiving surface (8a) of a needle thread guide (8), so as to be integral with the needle thread guide (8). The cam applies a tensile force, immediately before a looper enters, to a needle thread loop (6Lr) of a left needle thread (6L) which the looper enters finally in plural needle threads (6R, 6L) being received and supported on the thread receiving surface (8a) of the needle thread guide (8), as a movable needle thread take-up (3) rocks upward relative to rising movement of right and left needles (1R, 1L) from a bottom dead point. With this construction, it is avoided that the looper erroneously enters the plural needle thread loops, and a predetermined stitch is therefore formed reliably without causing skip-stitch.

摘要： Apparatus and method for detecting skipped stitches for chainstitch sewing machines (100) having a looper assembly (124) using a needle thread movement sensor (140) and/or a looper thread movement sensor (141) in combination with a shaft rotation sensor (130). Needle thread movement is correlated with needle shaft rotation per stitch cycle to detect instances when there is no needle thread movement during a stitch cycle (C). Similarly, looper thread movement may be correlated with needle shaft rotation per stitch cycle to detect instances when there is no looper thread movement during a stitch cylce (A). The invention includes methods for detecting needle loop (1B) and triangle skips (1C) by detecting instances of substantially no needle thread or looper thread movement during certain respective portions of the stitch cycle.

摘要： In a known sewing machine, the needle thread is not actually severed when the griffer thread runs out. Instead, a gap exists between the point of connection of the needle thread with the end of the old gripper thread and that of the needle thread with the new griffer thread. The aim of the invention is therefore to eliminate this weak point in the seam on the side facing the griffer. After a break in, or end of, a thread, the material stitched is moved backward by one stitch length, a new griffer thread is advanced and knotted by at least one stitch with the needle thread in the same stitching hole, in which the old griffer thread is also knotted in correct sequence with the needle thread. The process is suitable for making seams with sewing machines.

摘要： An automatic needle thread supply control system having a pair of clamping members (152A) disposed between the needle thread supply source and the needle thread take-up member (138), for clamping and releasing the needle thread (114). The moment when the clamping members start moving apart from each other and the period in which the clamping members are held apart from each other are controlled by control means according to the thickness of the work fabric or the thickness of the needle thread. While the clamping members are separated from each other, the needle thread is supplied from the needle thread supply source without restraint as the work fabric is fed. The needle thread is thus supplied under a tension conforming to the type of the work fabric in tightening the needle thread. During the free supply of the needle thread, the thread take-up member is held at the uppermost position, and hence the needle thread of an amount corresponding to the needle thread demand of the shuttle is supplied properly. After the supply of the needle thread has been accomplished, the clamping members are engaged to clamp the needle thread to prevent the excessive supply of the needle thread, while the thread take-up member starts its motion in phase with the vertical reciprocatory motion of the needle. To control the motion of the clamping members according to the thickness of the needle thread instead of the thickness of the work fabric, the control means is provided with proportional control means for engaging and for disengaging the clamping members at a speed proportional to the rotating speed of the arm shaft (128) of the sewing machine,
