    摘要: A motor controller for an electric sewing machine mounted in a removable portion of the housing of the machine. The controller is actuatable by a pneumatic switch which successively closes a plurality of contacts as the air pressure to the switch is increased to enable the speed of the motor to be increased smoothly and gradually without sparking at the contacts.

    摘要: A chain-stitch multi-needle quilting machine and method provide for driving needles and loopers independently or out of phase, particularly during the starting of stitching sequences. Separate drive motors drive needles separately from their loopers. Alternatively, a single motor drives needles and loopers linked through a differential drive or variably-controllable linkage. At the beginning of a stitch sequence, needles and loopers are separately driven in a split start manner by which stitches can be reliably formed by advancing the loopers ahead of the needles so the looper enters a needle thread loop before the needle enters a looper thread loop. Then the needle and looper can be brought into phase later in the first stitch cycle. The split drive can solve other stitch or thread control problems.

    摘要: A quilting apparatus for enabling a user to freely move a stack of fabric layers across a planar bed relative to an actuatable stitch head. The apparatus includes a motion detector which detects the movement of the stack and controls the actuation of the stitch head. Consequently, the apparatus functions to synchronize the delivery of stitch strokes by the head with the manually controlled movement of the quilt material stack. This frees the user to move the stack over a wide range of speeds, to start or stop movement at will, and to guide the stack in any direction across the planar bed.

    摘要: A sewing machine including a main shaft; a motor driving the main shaft; a needle bar; a sewing needle attached to a lower end of the needle bar; a needle-bar drive mechanism driven by the main shaft and vertically moving the needle bar; a speed setter setting a rotational speed of the main shaft; a needle-position detector detecting a vertical position of the sewing needle or the needle bar; a main shaft speed detector; a motor controller; and a needle plate; wherein the motor controller executes at least either of a first control decelerating the main shaft below the set rotational speed when the lower end of the sewing needle is above the needle plate, or a second control accelerating the main shaft above the set speed when the lower end of the sewing needle is positioned below the needle plate based on detected results provided by the detectors.

    摘要: Drapery sewing apparatus in which the sewing head is carried by a traveling carriage which traverses the work table, and a common drive propels the carriage and drives the stitching mechanism, the drive including a variable speed transmission through which the rate of travel of the carriage and the stitching rate are correlated. The table has a walkway and collapsible leaves for handling drapes of different lengths. The carriage is supported on rails and rollers adjacent to or on the table.

    摘要: A lockstitch sewing machine, particularly for use as an insole stitcher, having a stitching mechanism arranged for cyclically repeating operation and including a horizontally mounted rotary shuttle, has the shuttle arranged for rotation in a constant direction at a cyclically varying angular velocity such that a major part of each rotation, e.g., a complete rotation takes place in a minor part of each cycle, e.g., one quarter of the cycle. The rotation of the shuttle is provided, e.g., by a Geneva cam.

    摘要: A speed setting arrangement for a sewing machine comprises a permanent magnet mounted for unitary rotation with the foot pedal of the sewing machine, and a magnetic sensor including a plurality of magnetoresistors arranged in pairs to form a bridge circuit on a stationary plane spaced a distance from the plane of rotation of the magnet. The magnetic sensor provides an output signal which is exclusively a function of the magnetic orientation of the magnet and thus serves as a valid indication of the amount of pedal depression. An analog to digital converter is coupled to the magnetic sensor to convert its output into a digital signal for speed control purposes.

    摘要: The disclosure concerns a drive device for a double thread chain-stitch buttonhole sewing machine. The machine has a first drive shaft for driving the sewing needle and for moving the cloth support plate for sewing. It has a separate worm shaft for moving the cloth support plate to the sewing position and also for operating a knife for cutting the buttonhole. A first respective electromagnetic clutch operates the sewing needle drive shaft, and a second respective electromagnetic clutch operates an intermediate shaft which then operates the worm shaft for operating the cloth support plate and knife operating shaft are provided. A drive shaft is connected with the armature part of the first electromagnetic clutch on the sewing needle driving shaft. That armature part is gear connected with an armature part of the second clutch on the intermediate shaft. Activation of the clutches controls which of the shafts operates, as the clutches include rotors which rotate with respect to their respective shafts or are clutched to cause rotation of the shafts.
