    • The present invention provides an dispositif for a sewing machine which clamps the end of an upper thread for the next sewing job, wherein the upper thread is automatically cut after finishing sewing. The upper thread clamping device enables compatibility even when using presser feet with different widths. More specifically, the clamping device effectively clamps the upper thread even when using a narrow presser foot. Therefore, the clamping device is able to: prevent waste of sewing thread by maintaining the length of the upper thread from a needle as short as possible; effectively prevent separation of the upper thread from the needle; and effectively prevent entanglement of the sewing thread caused by unnecessary long lengths of the upper thread on the sewing surface when sewing starts. In the clamping device, a presser foot fixture (62) and a needle fixture (6) are vertically arranged on one end of an arm (1). The clamping device has the presser foot (63) which is connected to the presser foot fixture (62) by a press foot block (60) to enable vertical movement in the presser foot fixture (62). The clamping device is characterized in including: a drive generator (2) which is operated by the controller of a sewing machine; a pair of stoppers (70) which are installed on the press foot (63) and are arranged apart to place a needle (7) connected to the needle fixture (6) between the stoppers; and a holder (50) which has a holding lug (51) located between the stoppers and alternatively moves to the stoppers due to a connection with the drive generator (2). The holding lugs (51) are located on both sides of the stoppers due to the drive generator (2).
    • 本发明提供了一种用于缝纫机的装置,该装置夹住用于下一次缝纫工作的面线的末端,其中在完成缝纫后面线被自动切割。 即使在使用不同宽度的压脚时,面线夹紧装置也能兼容。 更具体地说,即使使用窄压脚,夹紧装置也有效地夹住面线。 因此,夹紧装置能够:通过尽可能缩短面线从针的长度来防止缝纫线的浪费; 有效地防止面线从针头分离; 并且有效地防止缝纫开始时由于缝纫表面上不必要的长线长度所引起的缝纫线的缠结。 在夹紧装置中,压臂夹具(62)和针夹具(6)垂直布置在臂(1)的一端。 夹紧装置具有压脚(63),该压脚通过压脚基座(60)连接到压脚固定装置(62),以使压脚固定装置(62)能够垂直移动。 该夹紧装置的特征在于包括:由缝纫机的控制器操作的驱动发生器(2) 一对安装在压脚(63)上的止动件(70),它们分开设置,以便将针(7)连接到针夹具(6)之间; 和一个夹持器(50),该夹持器具有一个位于止动器之间的止动凸耳(51),并且由于与驱动发生器(2)的连接而交替地移动到止动器。 由于驱动发生器(2),保持凸耳(51)位于止动器的两侧。

    • A thread wiper assembly mountable to the side of a sewing machine. The thread wiper assembly is particularly advantageous with sewing machines that are equipped with a walking foot. The thread wiper is mounted sidewardly relative to the needle and includes a picker arm, that while in a retracted position, is disposed sidewardly relative to the needle and out of its path of travel. Because the thread wiper is mounted to the side of the sewing machine and sidewardly relative to the needle, the picker arm is able to traverse along a path between the needle and the walking foot without interference. An actuating member: (i) lowers the picker arm in a direction substantially parallel to the needle until a free end of the picker arm is at a level between the needle and the walking foot; (ii) sidewardly thrusts the picker arm at a first angle, relative to a vertical axis, towards the needle along a path between the needle and the walking foot without interference; (iii) advances further sideways the picker arm at a second angle, relative to the vertical axis, greater than the first angle; and (iv) retracts away while raising the picker member in a reverse movement to complete the cycle. The thread wiper may include a microprocessor that is programmed to intelligently disable/enable the thread wiper depending on such factors as the adjustment in rise of the walking foot and/or whether the turn back operation of the sewing machine is activated. The thread wiper assembly is also suitable for use with a sewing machine that does not have a walking foot.
    • 可以安装到缝纫机侧面的螺纹刮水器组件。 刮线器组件对于配有步行脚的缝纫机是特别有利的。 螺纹刮水器相对于针安装在侧面,并且包括拾取臂,在拾取器臂处于缩回位置时,其相对于针向外设置并且不在其行进路径内。 因为刮线器相对于针安装在缝纫机的侧面并且相对于针侧面,所以拾取臂能够在不受干扰的情况下沿着针和步行脚之间的路径移动。 致动构件:(i)沿大致平行于针的方向降低拾取臂,直到拾取臂的自由端处于针和步行脚之间的高度; (ii)沿着针和行走脚之间的路径向相对于垂直轴线的第一角度侧向推动拾取器臂而不受干扰; (iii)相对于垂直轴线以第二角度进一步向前推进拾取臂,大于第一角度; 并且(iv)在反向运动中提升拾取器构件时缩回,以完成循环。 螺纹刮水器可以包括微处理器,其被编程为根据诸如步行脚的上升的调节和/或是否启动缝纫机的回转操作的因素来智能地禁用/使能螺纹刮水器。 刮水器组件也适用于不具有步行脚的缝纫机。

    • An overlock stitch is formed by sewing machine (11 fig. 1) into a work product (34) and the work product is accelerated away from the sewing machine so as to stretch the thread chain (Fig. 5). The stretched thread chain is cut by cutter (40), and the leading thread chain (43) recoils back toward the hollow chaining tongue (21) and is drawn into the chaining tongue by the stream of air (26) created by vacuum canister (52 Fig. 6). The next work product draws the leading thread chain out of the hollow chaining tongue and the sewing machine captures the leading thread chain in the stitch. Transfer conveyor (15 Fig. 1) moves the work product (34) into alignment with everter tube assembly (106), grippers (109 and 110) grip and open one end of the work product (Figs. 9-14), and air drawn through the everter tube assembly everts the work product. The gripper tube assembly opens along its lower portion (Fig. 16) and drops the work product.
