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： Die Erfindung betrifft ein Verfahren zum Betrieb einer Nähmaschine, insbesondere einer Doppelkettenstichnähmaschine, vorzugsweise einer Vielnadeldoppelkettenstichnähmaschine, die ein Nähorganpaar aus einer, in ein Nähgut einstechenden Nadel und einem unterhalb einer Nähgutauflage angeordneten, entlang einer Bewegungsbahn bewegbaren Greifer aufweist, wobei mit der Nadel ein Oberfaden durch das auf der Nähgutauflage aufliegende Nähgut geführt wird, der mit einem Unterfaden verbunden, insbesondere verkettet wird. Um ein gattungsgemäßes Verfahren zum Betrieb einer Nähmaschine derart weiterzubilden, dass zur Ausbildung eines sauberen Nähgutmusterbildes auf der Unterseite des Nähguts die erforderliche Fadenmenge des Unterfadens verringert wird, wird mit der Erfindung vorgeschlagen, dass der Unterfaden bedarfsweise mittels eines Schneidwerkzeuges geschnitten wird, das in einer Bewegung zumindest überwiegend nicht parallel zur Nähgutauflage, insbesondere entlang einer kreisbogenabschnittförmigen Bewegungsbahn entsprechend einer Bewegungsbahn einer Schwenkbewegung des Greifers bewegt wird.

摘要： A thread taking-up tool is attached to a needle bar sticking out of a sewing machine head, and its leading end has a plurality of thread holes. The thread holes of the thread taking-up tool are arranged in the lateral direction. A thread handling body has a cam face in the vertical direction. Needle threads from a tension device to needles are controlled by the vertical motion of the thread taking-up tool and the action of the cam face of the thread handling body. When the needles ascend from the lowest position, an endless hook attached to the thread taking-up tool is engaged with the left needle thread between the cam face lower end and the thread hole of the thread taking-up tool. Each thread is handled in with the left needle thread staying at the cam face lower end, so that the needle thread loop at the remotest end is absorbed surely.

摘要： The method and devices currently used to sew textiles, causing the sewing thread to fully penetrate the material to be sewn, require mechanical elements forming the stitches that are placed on both sides of the plane of the material to be sewn. This causes manipulation, mechanical and space-related problems when sewing large materials that should not be creased. The inventive method and the new device make it possible to sew the material in a one-sided operation and require minimum space. In order to produce the seam, two or more sewing needles (1,5) alternatively penetrate the entire sewing material (3). The loop (4) formed by a sewing thread is taken up by the next penetrating needle (5) and untied. The following penetrating needle then transfers the loops of the sewing thread. The sewing needles move three-dimensionally. The method and the device are suitable for sewing large, curved material that should not be creased, for example, reinforcement fabrics for fiber reinforced materials.

摘要： The present invention relates to an apparatus for preventing a double chain stitching from raveling. Looper thread engaging means engages with the looper thread consecutive to the looper from the cloth by moving when the looper is at the forward position and forms a looper thread loop consecutive from the cloth at the engaged portion by driving a sewing machine in said engaged state. A looper thread cutter cuts the looper thread loop at the engaged portion and a thread cutter cuts the loop-shaped needle thread consecutive to the needle via the looper from the cloth and the looper thread consecutive to the looper from the cloth between the cloth and the looper. Therefore, it is able to prevent that a double chain stitching ravels from said stitching end side. Further, defining means is provided to define the moving distance of the looper thread engaging means. The length of the looper thread loop is changed by definition of moving distance of the looper thread engaging means by the defining means. Therefore, the length of the thread end left over in the cloth by the looper thread cutter can be varied. By varying the length of thread end consecutive to the sewn end side, a good-looking sewn product is obtained.

摘要： The purpose of the present invention is to provide a stitch structure having little skin contact and having excellent product quality. This stitch structure (1) has a first surface (2) and a second surface (3) and comprises: a first fabric (4) having a first end section (4a); a second fabric (5) having a second end section (5a); a first stitching (11) that extends in a direction substantially parallel to the direction of extension (D) of the first end section (4a); a second stitching (12) that extends in a direction substantially parallel to the direction of extension (D) of the second end section (5a); a third stitching (13); and a tape-shaped member (14). The stitch structure (1) is characterized by: a first thread (T1) and a second thread (T2) being arranged in the first stitching (11) and the second stitching (12), respectively, so as to repeatedly return across and penetrate at least the first fabric (4) and at least the second fabric (5), in the thickness direction thereof; a decorative thread (T3) being arranged in the third stitching (13) so as to repeatedly span between at least the first thread (T1) and the second thread (T2); and the tape-shaped member (14) binding the first fabric (4) and the second fabric (5).
