摘要： A thread finger assembly for a sewing machine has at least one thread finger. The latter can be actuated between a loop engagement position and a loop pull-out position. The loop engagement position serves for the engagement of the thread finger in a thread loop generated by the sewing machine in a stitch forming region. The loop pull-out position is displaced relative to the loop engagement position for pulling out the thread loop with the thread finger, away from the stitch forming area. A thread finger drive serves for actuating the thread finger between the loop engagement position and the loop pull-out position. This results in an assembly of a sewing machine with which an appealing seam pattern is generated in a reproducible manner at a seam beginning.

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 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.

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. A two-needle sewing machine includes a bed part; a column part; an arm part; a needle shaft that is disposed on the leading part of the arm part; two sewing needles that are attached to the needle shaft; two horizontal hooks that catch the respective needle thread loops of the two sewing needles; and a conveyor member that conveys a material to be sewn in a direction approximately orthogonal to the bed part. On the two-needle sewing machine, the sewing needle, which is positioned in a location distant from the column part, is disposed closer to the conveyance side of the material to be sewn than the sewing needle that is positioned in a location closer to the column part.

摘要： A multi-needle chain stitch sewing machine with a thread thread severing system and method thereof for cutting needle threads between two isolated stitched patterns of a fabric. The multi-needle sewing machine includes a plurality of loopers and respective needles, a thread severing strip located in close proximity and transversely across each looper, and eccentric guides connected to the thread severing strip for extending the thread severing strip to cut the needle threads and for retracting the thread severing strip so that the thread severing strip does not contact the needle threads during the stitching operation. The method for sewing an array of isolated stitched patterns on a fabric including the steps of moving a plurality of loopers and respective needles to form an isolated stitched pattern; stopping the loopers after the needle thread is positioned around each looper; extending the thread severing strip, which is located in close proximity and transversely across each looper, in a direction toward the needle threads and in a side direction simultaneously such that the thread severing strip cuts the thread; and retracting the thread severing strip so as not to contact the needle thread during the stitch pattern forming operation.

摘要： In a two-needle sewing machine for making an ornamental stitch without a cover stitch, at least one intermediate lug (17) is provided which is disposed in side by side relation with respect to an upper thread take-up (13) engaged to the needle bar (7), said intermediate lug, in the absence of a workpiece (4) on the needle plate (8), is brought to a work position in which it interferes with one of the needle threads (4a, 4b) coming from an auxiliary thread take-up (12) being part of a feed unit for the needle threads. In the presence of the intermediate lug (17) in the work position, the orientation of the needle thread (4a) intercepted by said intermediate lug is suitably deviated with respect to the upper thread take-up (13), so as to cause a tension release on the needle thread itself during the raising steps of the needles (3a, 3) towards the upper dead center of their reciprocating motion.
