  • Control unit for “pilgrim step” operation of the detaching cylinders in a combing machine
    Patent number: 6393666
    Abstract: A control unit (10) for “pilgrim step” operation of the detaching cylinders (22, 23) in a combing machine, comprising a first electric motor, which rotates the circular comb (18) of the combing machine with uniform motion and a second electric motor (11), rotating a shaft (12), which houses the components to transmit motion to the detaching cylinders (22, 23). The first electric motor also operates at least one of the components that transmit motion to the detaching cylinders (22, 23), and the motor (11) is operated with a law of motion comprising acceleration and deceleration phases. Both motors mesh at all times and the first motor operates the components to transmit motion to the detaching cylinders (22, 23) by means of a differential device to obtain motion of the “pilgrim step” type.
