摘要： A presser foot 12c of a sewing machine is provided with a main body 210, a swayingly reciprocating mechanism section 230, and a thread hooking rod drive motor 240. The swayingly reciprocating mechanism section 230 has a thread hooking rod 236, and a needle thread receiving section for fixing a needle thread together with the thread hooking rod 236 is provided inside a leading-end structure section 216 of the main body 210. As a result of driving of the thread hooking rod drive motor 240, the swayingly reciprocating mechanism section 230 reciprocally moves while swaying with respect to the main body 210. When a thread take-up lever pulls up the needle thread, a circular movement arm which performs rotation movement while hooking the needle thread adjusts a rotational angle of the circular movement arm, thereby enabling adjustment of a length of a needle thread in one preceding stitch.

摘要： A thread feeding apparatus for a sewing machine which has a simplified mechanism for accuracy of manufacturing and improved durability so as to accommodate high speed sewing. The thread feeding apparatus for the sewing machine has upstream grippers for respectively gripping an upper looper thread and a lower looper thread, closed by a stitch forming device at the time of the stitch forming and opened at the time of the cloth feeding, downstream grippers for gripping the respective threads introduced from the respective upstream grippers, opened at the time of the stitch forming so that the respective threads are pulled by the stitch forming device and closed at the time of cloth feeding, and reciprocators which are respectively driven in a synchronous manner with a left needle, a right needle, an upper looper and a lower looper, at the time of cloth feeding. The reciprocators shift the respective threads in thread paths extending between the respective opened upstream grippers and the respective closed downstream grippers to pull off a thread quantity necessary for forming a stitch and, at the time of stitch forming, release the respective threads.

摘要： An overlock sewing machine which can switch its operation from an ordinary over-edge chain stitch to a rolled seam or vice versa with no requirement for a complicated operation of adjusting thread tension is obtained. This overlock sewing machine is provided with a spring for providing a thread with prescribed tension. The overlock sewing machine is further provided with a switching mechanism for switching the thread tension between that for the rolled seam and that for the over-edge chain stitch by switching the spring between a tensioning state and a non-tensioning state. Thus, the thread tension is readily switched between that for the rolled seam and that for the over-edge chain stitch.

摘要： A thread-pulling device is fastened on the arm of a sewing machine. The thread-pulling device has a thread clamp that can be opened and closed on the thread, and can be moved toward and away from the sewing machine arm. In operation, the needle thread, which has been pulled off the spool and extends to the sewing needle, is conducted through the thread clamp. After an initial seam has been completed, the thread clamp is closed on the thread and moved to an extended position which is remote from the arm. In this way, a given length of the needle thread is pulled off the spool, thus providing the proper length of needle thread for dependable formation of the first stitch of the following seam. Then, shortly after the start of the following sewing process, the thread clamp is moved back over an intermediate distance toward the sewing machine arm so as to pull back the initial piece of the needle thread that is now hanging down from the back of the material at the start of the seam. The initial piece of needle thread is pulled back to such an extent that only a short piece of the needle thread, of predetermined length, will remain on the back of the material.
摘要翻译：拉线装置固定在缝纫机的臂上。牵引装置具有可以在线上打开和关闭的线夹，并且可以朝着和远离缝纫机臂移动。在操作中，已经从卷轴拉出并延伸到缝纫针的针线被穿过线夹。在初始接缝完成后，线夹在线上闭合并移动到远离臂的延伸位置。以这种方式，将线的给定长度从线轴上拉出，从而提供适当长度的针线，以便可靠地形成下一缝的第一线迹。然后，在以后的缝制过程开始后不久，线夹在中间距离上向缝纫机臂移回，以便将现在从该材料的背面垂下的针线的初始片段拉回在接缝的开始。初始的针线件被拉回到这样的程度，即只有短片的预定长度的针线将保留在材料的背面。

摘要： A stitch forming machine is provided including a transducer for determining the tension present in a thread, wherein the thread tension assumes a higher value during stitch formation and the transducer provides a signal representing the tension level. The control is provided for evaluating the signal corresponding to the tension level. The control includes a comparator device for comparing a peak of the signal representing the tension level, which peak can be used to detect a malfunction, with a limit signal, corresponding to a limit tension. The comparator sends a signal to a switching device when a signal peak drops below the limit signal. The switching device may be connected to a shut-off device of the drive motor of the machine as well as one or more display elements. In this way, the machine may be stopped and the display element associated with a limit tension, below which the tension dropped by a switching device. The comparator may, according to another aspect of the invention, only provide a signal for energizing a switch depending upon a stitch formation phase associated with a signal peak which drops below a limit signal.
