Claims

[Scope of Claim for Utility Model Registration] The stitching part of a sewing machine that forms a chain stitch opening through the cooperation of the needle and looper, and the elastic force that normally presses against the throat plate, moves upward against the elastic force. A sewing machine includes a fabric presser that can be raised, a thread tension device that applies tension to the upper thread between the needle and a needle thread supply source, and that can release the needle thread tension in conjunction with the rise of the fabric presser. A stop means is connected to stop the sewing machine in response to a stop signal, and a stop means is disposed in front of the sewing portion in the cloth feed direction to detect the presence or absence of cloth and generates a detection signal in relation to passage of the trailing edge of the cloth in the cloth feed direction. Detection means 10, 11. S, and a conveying means 1 which is arranged at least forward in the cloth feeding direction with respect to the seam part and is capable of holding the cloth by suction with blood and air flow and moving from the seam part to the forward direction in the cloth feeding direction.
- 3.14, the first actuating means CL which acts in response to an electrical signal to hold the presser means upward, and the second actuating means CL which is capable of moving the conveying means in an operative state or in an inoperative state in which it is stopped by an electrical signal. The sewing machine has an actuating means CB, and a timer circuit which generates an actuating signal after the time required to form an empty ring of a predetermined length continuous to the trailing edge of the cloth in relation to the generation of the detection signal, and when the sewing machine is in a driving state, Generates a signal for activating the first actuating means and maintaining the second actuating means in an operative state in connection with the generation of the sensing signal, and maintaining the second actuating means in an inactive state in connection with the generation of the actuating signal. Control circuits F1 to F4 that generate signals and stop signals. T1
, T2, and a control device for a chain stitch sewing machine.
