  • the feed foot moves back and forth while moving up and down from above the throat plate.
  • the upper-and-lower feed sewing machines described in JP58-192576A and JP59-014881A further have an upper manipulator and a lower manipulator to move the respective cloths on the throat plate in a direction intersecting the cloth feed direction to keep the seam allowance constant.
  • Each of the upper manipulator and the lower manipulator has, on a distal end thereof, a roller for moving the cloth in the direction intersecting the cloth feed direction.
  • the rollers are rotated by respective pulse motors while detecting respective cloth edges by using a sensor, so that the seam allowance is kept constant.

Therefore, the workpiece pressing force can be finely adjusted by finely adjusting the current value. Further, the upper solenoid and the lower solenoid are driven by electric current. Thus, the pressing force of the solenoids can be adjusted with higher response as compared with the conventional mechanical pressing means.
  • control means individually controls the respective amounts of current to be applied to the upper solenoid and the lower solenoid. Therefore, by making the amounts of current applied different from each other, shirring sewing can be carried out.

  • the lower pulse motor 4 is fixed to the base 16.
  • the base 16 is provided with a swing arm 17 extending straight.
  • One end of the swing arm 17 is fixed to the base 16 together with the lower pulse motor 4, and the other end is a free end.
  • the lower roller 3 is rotatably supported.
  • the swing arm 17 is formed to have a bar shape, and the belt 15 is laid across the lower roller 3 and the output shaft of the lower pulse motor 4 so as to cover the swing arm 17. Accordingly, when the output shaft of the lower pulse motor 4 rotates, this rotation is transmitted to the lower roller 3 via the belt 15 to rotate the lower roller 3. That is, the lower pulse motor 4 functions as "lower driving means.”
  • the lower coupling mechanism 5 includes the above-described base 16 and swing arm 17, a rotary shaft 21, a drive lever 22, and a transmission link 23.
  • the base 16 to which the lower pulse motor 4 is fixed is formed to have a pentagonal shape, and the rotary shaft 21 is provided at one corner.

  • the transmission link 23 is a plate member extending in one direction, and with the other end portion of the transmission link 23, a plunger 62 of the lower solenoid 6 can come into contact from below.
  • the lower solenoid 6 is disposed so that the plunger 62 is movable in the vertical direction, and when the plunger 62 extends, it pushes up the transmission link 23, and when the plunger contracts, no member supports the transmission link 23 and the transmission link moves down.
  • the housing 60 of the lower solenoid 6 is provided with a support base 61, and when the plunger 62 is not driven, the support base supports the transmission link 23 from below.
  • the lower solenoid 6 is disposed so that the plunger 62 moves along the vertical direction of the sewing machine (vertical direction of the needle).

According to this shape, a specific stroke section (described in detail later) in which a thrust does not depend on a stroke is obtained.
  • the lower solenoid 6 obtains the characteristics shown by the hysteresis curve in Fig. 7 concerning stroke to thrust when applied current is fixed. That is, a specific stroke section W in which a thrust does not depend on a stroke of the plunger 62 is obtained.
  • the lower solenoid 6 is attached in a direction in which the lower solenoid pulls-in the plunger 62 by energizing the coil 64. In accordance with an increase in the applied current, thrust for pulling-in the plunger 62 is increased.
  • the lower solenoid 6 generates thrust in proportion to a square of the current applied. That is, an amount of change in thrust with respect to a current change increases as the generated thrust increases. Therefore, with a small thrust, a small amount of change is obtained and a slight change in pressing force becomes possible, and with a great thrust, a large amount of change is obtained and the pressing force can be comparatively widely changed, so that the pressing force adjustment of the lower roller 3 becomes easy.
  • the lower solenoid 6 functions as "lower pressing means.”
  • the upper roller 7 is provided above the throat plate 14, and comes into contact with the upper cloth from above and moves the cloth in a direction crossing (for example, orthogonal to) the cloth feed direction of the feed dog 1.
