摘要： A suturing device includes: a needle; and a shuttle. The needle has an elongated shape extending in a predetermined direction and is configured to hold a first thread-like member. The needle is reciprocally movable forward and backward in the predetermined direction and is rotatable about an axis extending in the predetermined direction. Rotation of the needle about the axis permitting the first thread-like member to cross the needle to form a loop in the first thread-like member. The shuttle includes a holding portion. The holding portion is configured to hold a second thread-like member. The shuttle is configured to permit the holding portion to pass through the loop.

摘要： A bobbin thread winding apparatus which can reliably twine a bobbin thread around the bobbin within the bobbin case. With the reliable twining of the thread, the thread is not cut and also will never be forced out of the bobbin case, thereby forming a good seam. Since the thread is not wound around a shaft other than the bobbin shaft, no manual operation is required for resetting the thread to the clamping mechanism, improving the reliability of the bobbin thread winding apparatus. The bobbin thread winding apparatus can accurately detect an effective thread winding amount of the bobbin thread irrespective of the yarn count of the thread used, and does not apply an excessive load to the thread winding mechanism, causing any adverse effect on the stitching quality. The bobbin thread winding apparatus allows a lower thread to be drawn out of the thread supply source and is then securely twisted around the bobbin shaft without a thread draw-out mechanism. Without the need to forcibly draw out the lower thread out of the thread supply source, the cost to manufacture the apparatus is reduced and its reliability is increased.
摘要翻译：一种底线卷绕装置，其能够可靠地将梭芯缠绕在梭壳内的线轴上。通过螺纹的可靠缠绕，螺纹不被切割，也不会被迫离开梭壳，从而形成良好的接缝。由于线圈没有缠绕在除了轴筒以外的轴上，因此不需要手动操作来将线路复位到夹紧机构，从而提高了底线卷绕装置的可靠性。底线卷绕装置可以精确地检测底线的有效螺纹卷绕量，而与所使用的螺纹的纱线数量无关，并且不对卷线机构施加过大的负荷，对缝合质量造成任何不利影响。底线卷绕装置允许下线从线供给源拉出，然后在没有拔线机构的情况下可靠地绕着绕线轴扭转。不需要强力地从线供给源中抽出底线，制造装置的成本降低，其可靠性提高。

摘要： Transfer mechanism (20) is provided for reciprocally transferring a bobbin grasping device (10), grasping a bobbin case (B) at the distal end of a chuck section (11), between a rotary hook (6) of a sewing machine and a bobbin stock section (8). First cam plate (31) is provided adjacent to one end for orienting the chuck section (11) toward the rotary hook (6) during the transfer, while a second cam plate (41) is provided adjacent to the other end for orienting the chuck section (11) toward the bobbin stock section (8) during the transfer. The cam plates (31, 41) are detachable from the transfer mechanism (20), and, in transportation of the machine, one of the cam plates is transported as an attachment to a main sewing table, while the other plate is transported as an attachment to an extension sewing table. The bobbin grasping device (10) includes a moving body section (13), chuck section (11), and a spring member (19) for normally biasing the chuck section toward a predetermined neutral position.

摘要： A hook (15) of a sewing machine (1) is pivotably mounted on a hook carrier (25). The hook (15) is moved from a working position (X) into a bobbin case withdrawal position by a pivoting movement of the hook carrier (25). The pivoting movement displaces the hook (15) and the bobbin case (17) towards or above the opening which is opened by the flap (13) in the lower arm (13). In this way, the withdrawal of the bobbin case (17) or the bobbin is significantly simplified.

摘要： A lower thread supply device of a sewing machine includes a bobbin, a bobbin case, a magnetic force member, and a magnetic force change portion. The bobbin has a cylindrical portion for inserting into a spindle of a shuttle, a shuttle side flange portion, and a front surface side flange portion which is magnetic, and a lower thread is wound around an outer circumference of the cylindrical portion between the shuttle side flange portion and the front surface side flange portion. The bobbin case has a non-magnetic cover portion having a front surface side part and a side wall part, housing the bobbin and transmitting a magnetic force. The magnetic force member is arranged at the front surface side of the bobbin case and attracts the front surface side flange portion of the bobbin by a magnetic force via the bobbin case.
