description | An anglebar and/or a compensator roller in a folder of a printing press is adjustable. A motor has an output shaft operatively connected with the anglebar and/or the compensator roller to, when driven, adjust the position of the anglebar and/or the compensator roller. A tachometer provides a speed reference signal indicative of the speed of movement of a web of sheet material relative to the anglebar and/or the compensator roller. A web position sensor provides an adjustment control signal indicating that the anglebar and/or the compensator roller should be adjusted. A computer responds to the speed reference signal and the adjustment control signal to control a DC drive. The DC drive drives the motor at a speed which varies with the speed of movement of the web of sheet material. The anglebar and/or the compensator roller is thereby moved to a desired position at a rate which is a function of the speed of movement of the web of sheet material relative to the anglebar and/or the compensator roller. |
