摘要： A sewing machine including a needle bar having a sewing needle, a spindle for driving the needle bar, a bed portion movable selectively to a using position or a retracted position, and a rotary hook housed in the bed portion. A stitch is formed by the cooperation of the sewing needle and the rotary hook. A rotary hook drive motor is provided in the bed portion for driving the rotary hook. A sensor is provided for detecting a position of the bed portion. The needle bar and the spindle is selectively disconnected from each other. If the bed portion is out of the using position, and this out position is detected by the sensor, the needle bar is released from the spindle for stopping the sewing needle. Further, in this case, the rotation of the rotary hook drive motor is also stopped.

摘要： A sewing machine includes a plurality of needle bars for performing stitching with multiple needle threads. The needle threads have diameters, tenacity, and stretchability different from one another. Sewing parameters inherent to each of the needle threads are beforehand determined. The parameters are maximum sewing speed, thread breakage sensitivity, thread residual amount, needle-rotary hook meet angle, workpiece fabric feed timing, and feed pitch. A spindle motor, a thread cutting motor, a rotary hook drive motor, an X-axis motor, and a Y-axis motor are controlledly driven based on the selected parameters inherent to the just used needle thread.

摘要： A multihead sewing machine includes a sewing machine motor, a main shaft rotated by the sewing machine motor, a plurality of sewing needles driven by the main shaft, a plurality of shuttles for capturing thread loops in cooperation with the sewing needles respectively, each shuttle having a hook shaft, and a plurality of shuttle driving motors for rotating the hook shafts of the shuttles independent of the sewing machine motor respectively. The sewing machine motor and the shuttle driving motors are controlled so that the sewing machine motor and each shuttle driving motor are rotated in synchronism with each other. Loss of synchronism of each shuttle relative to the corresponding sewing needle is detected. Rotation of the main shaft is stopped in an abnormal condition in which the loss of synchronism has been detected with respect to at least one of the shuttles. Furthermore, at least the shuttle driving motor or motors other than the shuttle driving motor regarding which the loss of synchronism has been detected are rotated in synchronism with the main shaft until rotation of the main shaft stops.

摘要： A needle bar stopper is provided in a sewing machine having a main shaft and a needle bar which moves vertically upon reception of a driving force from the main shaft. The needle bar stopper comprises a transmission prohibiting unit, including a needle bar stopping solenoid, which prohibits transmission of the driving force from the main shaft to the needle bar and a braking unit, including a needle bar stopping solenoid, which applies a braking force to the needle bar when transmission of the driving force is prohibited by the transmission prohibiting unit. The needle bar stopper can stop the needle bar reliably by use of the braking unit.
