- Function drawing
A wide band sensor detects the current web position of the single faced corrugated board web. The position controller compares the target and actual value and outputs a corresponding corrective signal to the control roller, in order to regulate the web towards the web center. Skewed positioning of the control roll initiates a correction of the single faced corrugated board web.
Area of use
In the corrugated board system, on the bridge
On the bridge, directly after the loop storage
