摘要： PROBLEM TO BE SOLVED: To provide a looper selection structure suitable for carrying out chain stitch with multicolor threads to a cylindrical workpiece by improving a moving structure for selecting one of a plurality of loopers.
SOLUTION: The looper part (5) arranged under a needle plate (8) is obtained by arranging a plurality of loopers (18) along a curved moving path, and comprises moving mechanisms (13, 17, 19 and 28) for selectively positioning one of the loopers (18) at a prescribed needle dropping position by moving the plurality of loopers (18) along the curved moving path. Chain stitch is carried out by cooperation between a hook needle (4) to be reciprocated and the looper (18). Regarding the looper part (5), one end including the needle dropping position projects, and the cylindrical workpiece can be put in and out from the one end. The curved moving path has a U-shape.

摘要： PURPOSE:To prevent the end of a thread from being left outside a bobbin by providing a thread clamping means for clamping/-releasing a lower thread to be taken up around a rotating bobbin at the opening part of a bobbin case and rewinding the lower thread inside the bobbin with a take-up rod when the lower thread is unfastened by the approach of a wiper for applying tensile force to the lower thread. CONSTITUTION:A lower thread 150 to be taken up around the rotatable bobbin is supplied and taken up through a long hole 92a of a thread guide 92 to the bobbin inside a bobbin case 8 while applying tensile force with a wiper 130. A thread clamping means 105 for clamping and releasing the lower thread 150 is provided at an opening part 8A of the bobbin case 8. When the lower thread 150 is unfastened by the approach of the wiper 130, the thread clamping means 105 is released, a take-up rod 107 is turned, and the thread end part of winding start is taken up inside the bobbin. Thus, the end of the thread is prevented from being left outside the bobbin, and beautiful seams are formed.

摘要： PURPOSE:To obviate the need for antimolt treatment for a yarn in an annular part at the sewing end point of each yarn in chain stitching. CONSTITUTION:This method for chain stitching is to move a crochet needle to a top dead center after completing the chain stitching with one colored yarn in the chain stitching, remove the crochet needle 8 from an annular part (36c) formed of the colored yarn, direct the crochet needle 8 in a state thereof passing through the annular part (36c) toward a looper 12' in starting the stitching of the next colored yarn, pass another colored yarn 136 from the looper 12' through the annular part (36c), pull up the colored yarn 136, then advance the stitching with the second and third needles while successively moving a fabric 35 in the direction of an arrow 37 and thereby stitch and fix the annular part (36c) to the fabric 35 with another kind of yarn (136b) between the stitches with the second and the third needles.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of skip stitch failure by closely contacting up and down two sewing threads positioned in the upside of a thread handier when halfway parts of the two sewing threads linked between cloth and a louver are collected by a thread handler and withdrawing them from the reciprocating passage of the needle. SOLUTION: When the sewing needle is descending, this thread handier 10 to move for-/back-ward in the A-B direction shown by the arrow mark proceeds to the A-direction to hang and draw halfway parts of a two threads (loop parts) 5a, 5b linked between cloth and a louver 4 toward the side of the descending position of a sewing needle 1 and, when the sewing needle is ascending, the thread handier 10 recedes. The string handier part 11 is formed opening in an almost V-shape in the direction to collect the sewing thread 5a, 5b on the tip end part of the sewing needle 1 and a sewing thread inserting part 12 is formed on the central part of the thread collector 11. Skip stitch failure by proceeding the sewing needle 1 in between the sewing threads 5a, and 5b is prevented by bringing the halfway parts of the sewing threads 5a, 5b into a close contact condition.

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 provide the horizontal shuttle of a sewing machine requiring no opener. CONSTITUTION:A horizontal shuttle is provided with an outer shuttle having a tip and rotatively driven in the preset direction and an inner shuttle 60 storing a bobbin 10 wound with a bobbin thread, relatively movably coupled with the outer shuttle 2, and having an inner shuttle stop 3 rockably coupled at the preset angle between a pair of stoppers 9a, 9b formed on a needle plate 8 and blocking the co-rotation with the outer shuttle 2. The inner shuttle 60 is provided with a needle thread pad 61 temporarily hooking a needle thread 50 near the inner shuttle stop 3 on the rotation direction side of the co-rotation with the outer shuttle 2 so that the inner shuttle 60 is rocked in the opposite direction to the rotation direction of the outer shuttle 2 by the tension of the needle thread 50 when the ring of the needle thread 50 captured by the tip passes through the inner shuttle 60. No opener mechanism is required, and the shock sound can be reduced.
