摘要： A sewing machine includes a needle plate, a feed dog configured to move a workpiece, a vertical drive mechanism configured to vertically drive the feed dog, a switch mechanism, a cutting mechanism, and an actuator. The switch mechanism is configured to switch from an active state where the feed dog is driven, by the vertical drive mechanism, above and below an upper surface of the needle plate to an inactive state where an upper surface of the feed dog is maintained below the upper surface of the needle plate. The cutting mechanism includes a blade configured to cut a thread at a position below the needle plate. The actuator is configured to commonly drive the switch mechanism and the cutting mechanism.

摘要： A sewing thread (20) can be captured certainly with a thread capturing open eye (13a) of an open eye needle (13) and the stitches are formed in the inner space of a sewing machine bed (3). A handstitch and a locked stitch are formed, respectively, on the front surface and the back surface of a fabric workpiece (21) as a skip stitch set through cooperation of the open eye needle (13), a shuttle hook (200) and a thread draw out actuator (401). A feed dog (601) feeds the fabric workpiece by a stitch length (P1) for handstitch during a first stroke of the open eye needle (13), and feeds the fabric workpiece by an inter-stitch pitch (P2) between the handstitches during a second stroke of the open eye needle (13).

摘要： An electrically controlled sewing machine includes a needle bar, a needle plate, a feed dog, a feed dog vertical drive mechanism, a feed dog front/rear drive mechanism, an embroidery drive mechanism, and a feed dog retraction mechanism. The feed dog retraction mechanism includes a switching operation lever. The feed dog vertical drive mechanism includes a normal sewing drive cam and a retraction drive cam, which are switched between using the switching operation lever. The retraction drive cam drives the feed dog to rise upward by about 1 mm when the upper thread is being tightened, that is, at about 40.degree. to 90.degree. phase at the end of the thread tightening operation by the upper thread take-up lever. Because the feed dog moves upward only about 1 mm, it remains retracted below the level of the needle plate and will not interfere with movement of a workpiece cloth mounted in an embroidery frame. However, because the feed dog moves upward, the lower thread and the upper thread loop, which is being tightened at this point, can easily be pulled through the space between the connection portion at the front end of the feed dog and the vertical axis oscillating shuttle position beneath the connection portion of the feed dog. The lower thread and the upper thread loop can pass through the space without any resistance. Therefore, the thread tension will not degrade, so that attractive stitches can be formed.

摘要： This disclosure relates to a four motion feed mechanism for sewing machines that is adapted to advance a work piece past the stitch forming point of the machine. Orbital movement is imparted to the feed dog by a drive mechanism including first and second linkage assemblies driven off a common eccentric arranged on the sewing machine bed shaft. A feed lift regulatory assembly is operatively connected to one of the linkage assemblies and is provided to selectively modify the amplitude of lift that is imparted to the feed dog of the machine.

摘要： In feed dog mounting/unmounting mechanism, lever is slidably provided to feed base in the front-rear direction, and is forced backward by a lever force-applying spring. Upon sliding lever rearward, fixing target portion of feed dog 22 is fixedly held by base-side fixing portion of feed base and lever-side fixing portion of lever arranged in the front-rear direction. Stopper is provided to feed base so as to be movable in the upper-lower direction, and holds lever. When feed dog is mounted, stopper is pressed downward by feed dog, which moves stopper so as to allow lever to slide. With this, lever is slid due to force applied by the lever force-applying spring, thereby allowing fixing target portion to be held, interposed between base-side fixing portion and lever-side fixing portion.

摘要： A sewing machine includes a feed dog disposed in a bed of a main body to be displaced between positions above and below a top face of the bed in a normal state to feed a workpiece cloth, and a control device. When a presser foot is vertically moved during sewing, the control device judges that the feed dog is in the drop feed state. The vertical movement of the presser foot is detected on the basis of an output of a cloth thickness sensor which detects the height of the presser foot. When the feed dog is in the drop feed state, the control device judges whether a stitch pattern selected by a user is suitable for formation of stitches in the drop feed state of the feed dog. When the stitch pattern is unsuitable, information to that effect is provided, and the sewing is stopped.
