摘要： An inner rotary hook has a needle drop hole, and side wall portions formed over the drop hole and defining a space for passage therethrough of a sewing needle. The side wall portions are located adjacent to opposite sides of the needle passing through the space and extend from a region in front of the needle to a region behind the needle. The side wall portions can abut against an upper thread, passed through a hole of the needle, near a bottom dead point of the needle. If any of two portions of the thread located forward and rearward of the needle has strayed laterally, it can abut against one of the wall portions. Consequently, it is possible to prevent the front-side upper thread portion from circling around behind the needle, but also prevent the rear-side upper thread portion from straying laterally to form a laterally-protruding loop.
摘要翻译：内旋转钩具有针滴孔，侧壁部形成在滴孔上并限定缝合针通过的空间。侧壁部分位于穿过空间的针的相对侧附近并且从针的前面的区域延伸到针后面的区域。侧壁部可以靠近针的底部死点附近穿过针的孔。如果位于针的前方和后方的螺纹的两个部分中的任一个横向偏离，则其可以抵靠壁中的一个部分。因此，可以防止前侧面线部分在针之后盘旋，而且可以防止后侧面线部分横向偏离以形成横向突出的环。

摘要： A half-turn hook for positioning a needle thread loop between a needle and a bobbin at the time of stitching, the half-turn hook comprises a shuttle race body, a rotatable shuttle body, a bobbin and a shuttle race ring. The shuttle race body has a sliding surface on which a needle thread is slid in the beginning of stitching. The shuttle race ring has a cutout formed in its upper portion. In the half-hook, the surface where the shuttle body abuts against the shuttle race body and the end into which the rotating shuttle digs, in the cutout of the shuttle body race ring, is located closer to the rotating shuttle body than the sliding surface of the shuttle race body.

摘要： A bobbin-thread supply device for a sewing machine. The operator inserts the bobbin into the bobbin holder, draws bobbin thread from the bobbin, and passes the tip of the bobbin thread through the slit in the cover above the bobbin holder. Since the slit in the cover extends above where the tension bracket is joined onto the tension spring, the bobbin thread is guided between the tension bracket and the tension spring through the tension regulating portion. The bobbin thread can thus easily be set with appropriately tension applied thereon. At the same time, the length of the bobbin thread can be adjusted for proper sewing operation.
摘要翻译：缝纫机用线轴供给装置。操作人员将筒管插入筒管夹持器中，从筒管抽出底线，使底线尖端穿过筒管架上方的盖板上的缝隙。由于盖中的狭缝延伸到拉伸支架接合到拉伸弹簧上方的上方，所以底线通过张力调节部分在张力支架和拉伸弹簧之间被引导。因此，可以容易地将底线设置成施加适当的张力。同时，可以调整底线的长度以进行适当的缝纫操作。

摘要： A device for guiding a lower thread in a zigzag stitching sewing machine is provided with a lower thread guiding unit that determines two lower thread drawing positions in accordance with a selected pattern. The lower thread guiding unit includes a lower thread guiding part which, at one of the two positions, acts on the lower thread to guide a lower thread drawing position to a center of a needle amplitude. A lower thread releasing element, at the other of the two positions, cooperates with the lower thread guiding unit to release the lower thread engaged with the lower thread guiding part.

摘要： A rotary looptaker includes a looptaker body rotatable about a vertical axis and a bobbin case restrained from rotary motion with the looptaker body. A plurality of annular protrusions are provided on a flange of the bobbin case so as to extend in a circumferential direction of the bobbin case and are in engagement with a flat surface formed on a raceway of the looptaker body. When the looptaker body is rotated, the bobbin case slides relative to the looptaker body through a very small contact area between the annular protrusions and the flat surface, thus reducing sliding friction between the looptaker body and the bobbin case. Accordingly, noise and vibration are decreased when a rotation restraining projection of the bobbin case contacts a restraint element secured to a machine frame.
摘要翻译：一种旋转打纬器包括可围绕竖直轴线旋转的吸收体，以及与吸收体相对应的旋转运动的梭壳。在梭壳的凸缘上设置有多个环形突起，以便在梭壳的圆周方向上延伸并且与形成在吸收体本体的滚道上的平坦表面接合。当吸收体旋转时，梭壳通过环形突起和平坦表面之间的非常小的接触面积相对于吸收体主体滑动，从而减小了吸收体与梭壳之间的滑动摩擦。因此，当梭壳的旋转抑制突起接触固定在机架上的约束元件时，噪音和振动减小。
