Functional description
The sensors locate the position of the web edge and send this information as an analogue
signal to the electronic control unit. The control unit compares the position feedback signal
with the reference. If there is a difference the steering frame will be adjusted.

The steering frame consists of a fixed lower and a moveable upper frame that supports the
rollers. The upper frame is activated by a DC-Servo-Motor. A location slot for easy sensor
attachment is integrated to the steering frame.

The electronic control unit contains a micro-processor that handles all calculations and
communications. The DC-Servo-Motor to drive the steering frame, the rotary switch and
potentiometer are integrated.
