摘要： A thread-chain separating head, in particular for a double chainstitch sewing machine, comprising a heating wire for thermically separating the thread chain and comprising a suction tube for leading the thread chain towards the heating wire. Said heating wire is arranged laterally and outside of the suction tube in order to achieve advantageous conditions during the heating and separating operation.

摘要： A thread tensioning device comprising a stationary electromagnet mounted on a sewing machine arm and a tensioning wheel having a relatively low mass. The tensioning wheel is rotatable concentric to a longitudinal axis of the electromagnet and is mounted on the electromagnet so as to be moveable only slightly in the direction of the longitudinal axis. A friction disk is positioned at one end of the electromagnet so as to be between the electromagnet and the tensioning wheel. A current flows through an excitation winding in the electromagnet and its value is varied within given limits by a suitable current control device, thereby causing the electromagnet to pull a flat side of the tensioning wheel with corresponding force against an application side of the friction disk, whereby a corresponding variable thread tensioning force is applied to a sewing thread passing through the tensioning wheel to the sewing machine.
摘要翻译：一种线张紧装置，包括安装在缝纫机臂上的固定电磁体和质量相对较低的张紧轮。张紧轮可以与电磁体的纵向轴线同心地旋转，并且安装在电磁体上，以便能够在纵向轴线的方向上稍微移动。摩擦盘位于电磁铁的一端，以便在电磁铁和张紧轮之间。电流流过电磁铁中的激励绕组，其值通过适当的电流控制装置在给定的限度内变化，从而使电磁铁以对应于摩擦盘的使用侧的相应力拉动张紧轮的平坦侧，由此将相应的可变线张力施加到通过张紧轮的缝纫线到缝纫机。

摘要： A device for controlling the looper thread of a double chainstitch sewing machine has a looper which can be oscillatingly driven in the sewing direction. A link mechanism is provided to drive the spreader, said link mechanism being designed as a six-bar linkage mechanism with a four-bar linkage and a secondary two-link group. The basic linkage and the two-link group are arranged in such a manner that two links are guided during a movement of the spreader in an extreme position in which it does not spread the looper thread. Thus a spreader movement is produced which is particularly adapted to the sewing process.
摘要翻译：用于控制双链式缝纫机的弯针线的装置具有能够沿缝制方向振动地驱动的弯针。提供连杆机构来驱动吊具，所述连杆机构被设计成具有四杆联动装置和次级双连杆组件的六杆连杆机构。基本连杆和双连杆组以这样的方式布置，即在扩展器在不扩展弯针螺纹的极限位置的运动期间引导两个连杆。因此，制造了特别适合于缝纫过程的吊具机芯。

摘要： A throat plate of an automatic sewing arrangement producing a double lockstitch and having a feeding device for generating a feed motion in any direction in a sewing plane as a relative movement between the needle and a workpiece. The throat plate is formed at the surface turned towards the workpiece with a closed needle aperture area, and is formed at the surface turned away from the workpiece with an opened needle aperture area profiled with a thread guiding edge affecting the hook thread leaving the double lockstitch hook. The thread guiding edge controls the position of the hook thread with respect to the needle so as to avoid a double interlocked stitch formation.
摘要翻译：一种自动缝制装置的喉板，其生产双折线，并具有用于在缝纫平面中的任何方向上产生进给运动的进给装置，作为针和工件之间的相对运动。喉板形成在具有闭合的针孔面积的朝向工件的表面上，并且形成在远离工件的表面上，打开的针孔区域与引导边缘成对，该线引导边缘影响钩螺纹，离开双锁缝钩。线引导边缘控制钩线相对于针的位置，以避免双重互锁针迹的形成。
