摘要： In thread cutting mechanism portions of a lower thread winding device, two groove portions of an inner threading groove portion and an outer threading groove portion are formed on a holder. In the inner threading groove portion, one end portion is opened to one of an intersecting direction intersecting with a radial direction of the holder at an outer peripheral portion of the holder and another end portion is located at an inner side of a small-diameter bobbin in the radial direction. The outer threading groove portion is located at an outer side of the inner threading groove portion in the radial direction of the holder. In the outer threading groove portion, one end portion is communicated with the inner threading groove portion and located at the outer side of a large-diameter bobbin in the radial direction and another end portion is located at the inner side of the large-diameter bobbin in the radial direction.

摘要： In an embroidery sewing machine having a lower thread winding device, when the non-lower thread state of the bobbin is detected by a residual amount sensor, a sewing machine motor is stopped to detect and recognize the size of the embroidering frame of an embroidering device by means of a frame size sensor and the embroidering frame is moved corresponding to the size to position the corner of a workpiece held in the embroidering frame under a needle. Then, an extra sewing operation is carried out over the corner to consume the lower thread remaining in the bobbin, and subsequently, it is decided whether or not the embroidering frame is moved by a distance required for completely extracting the lower thread from the bobbin (an amount of the residual lower thread is detected when the non-thread state is detected by the residual amount sensor). If the distance is insufficient, the destination of the embroidering frame is updated to repeat the extra sewing operation over the next corner of the workpiece S, thereby completely extracting the lower thread from the bobbin.

摘要： A magnetically detectable bobbin for a sewing machine. The apparatus includes a substantially non-metallic detectable bobbin core. The core includes a substantially non-metallic cylindrical body having a detectable dopant in the cylindrical body. In the preferred embodiment, the dopant is magnetite. The thread supply is wound about the bobbin core after a frictional outer surface is applied to the bobbin core to aid in windability of the thread supply.

摘要： An automatic dual bobbin mechanism is provided. A housing containing two unique bobbin casings and bobbins therein oriented side-by-side with the sewing needle and thread passing between the bobbin casing pair replaces the convention single bobbin configuration. The bobbin pair acts in a tag-team operation whereby one bobbin supplies thread to be stitched into a fabric while the second bobbin is simultaneously filled with thread from an external source. When the first bobbin is emptied, the bobbin pair is rotated 180.degree. inside the housing. The second bobbin, now full, supplies thread for continued stitching while the first bobbin is refilled with thread supplied by the external source. The specially designed bobbins and bobbin casings allow for automatic rethreading of the empty bobbin and cutting of the bobbin thread from external source, thus eliminating the need to manually remove the empty bobbin and assembly, replace with a full bobbin and rethread.
摘要翻译：提供自动双线轴机构。包含两个独特的筒管和其中的线轴的壳体与缝纫针和穿过筒管套之间的线并排定向，代替了常规的单筒管配置。线轴对以标签组合的方式起作用，其中一个纱管将待缝合的织物缝合到织物中，而第二纱管同时从外部源填充线。当第一个筒管清空时，筒管在壳体内旋转180°。当第二个线轴被外部电源提供的线圈重新填充时，第二个线轴现在已满，为连续缝合提供线。专门设计的线轴和梭壳允许自动重新套管空筒管和从外部源切割底线，从而无需手动取出空筒管和组件，更换为全筒管并重新布线。

摘要： In the invention, the sewing machine carries out winding of the thread by operating separately a thread winding mechanism and a clutch mechanism. A speed detector is provided to measure actual rotary speed of a mechanism which is related with rotation of an upper shaft. If the thread winding were carried out, while said mechanism is left as engaged with a power source of the sewing machine, the speed detector would detect the rotation of said mechanism to stop a machine motor instantaneously, so that the thread winding cannot be performed when said relative mechansim is not released from the power source, and the needle bar is not actuated at winding the thread for safety in operation.

摘要： The winder shaft for a sewing machine, fashioned as a support for a thread bobbin, is positioned directly on the shaft of a low-voltage motor, independent of the drive motor for the sewing mechanism of the sewing machine. An on/off switch for this motor is operable by means of a three-armed switching lever, with the first arm being adapted to scan the package of wound thread forming on the bobbin. A trigger cam disposed on the third arm slides, during this operation, over a first surface of a spring-biased dual ramp. Once the thread bobbin is full, the trigger cam surpasses the apex of the dual ramp, and the switching lever flips into a disconnect position and cuts off the motor by way of a switching cam disposed on the second arm. All of the elements of the spooling device are mounted to a common support so that the spooling device, which is independent of the drive mechanism of the sewing machine, can be attached as a composite unit at any desired location on the sewing machine.
摘要翻译：用于缝纫机的卷绕轴，作为线轴的支撑件，直接位于低压电动机的轴上，与用于缝纫机缝纫机构的驱动电机无关。该马达的开/关开关可通过三臂切换杆操作，其中第一臂适于扫描在筒管上形成的缠绕线的包装。设置在第三臂上的触发器凸轮在此操作期间在弹簧偏置的双斜坡的第一表面上滑动。一旦线筒筒满了，触发器凸轮超过双斜面的顶点，并且开关杆翻转成断开位置，并通过设置在第二臂上的切换凸轮切断电动机。绕线装置的所有元件安装到共同的支撑件上，使得独立于缝纫机的驱动机构的绕线装置可以作为复合单元附接在缝纫机上的任何所需位置。
