Web guides for rotative presses

SG 9000 is an economic edge guide suited for all kind of printing press or converting machine. The system checks and controls the position of the edge of the material. SG 9000 logic control is user friendly and it is used for controlling a positioning frame. The correction signal leads an electrical linear actuator with end switches and servo center. The measured error is controlled by reflective photocells or ultrasonic sensors or infrared sensors.



All the parameters are settable by the operator control logic. The system shows the measured error on an LCD display that shows graphically and numerically the deviation values. The zero setting can be modified for moving the offset level. In the most sophisticated systems the sensor can be motorised.



The auto-center device is used for moving the edge guide in a central position in order to start a new job with the same potential correction on both the sides.
