Abstract
A control system is used in combination with a tilt-box arrangement for controlling the transverse displacement of a web and having a stationary support frame and a roller frame pivotal on the support frame about a frame axis and carrying at least one roller rotatable about a roller axis transverse to the frame axis. The web is engaged over the roller and moves in a transport direction transverse to the frame axis and to the roller axis. A drive is connected between the support and roller frames and operates to pivotally displace the roller frame in opposite angular directions from a center position with the roll axis perpendicular to the transport direction toward respective end positions and thereby laterally deflect the web engaged by the roller. The system comprises a sensor holder provided on one of the frames and having two respective end-position sensors and a center-position sensor, a stop holder provided on the other frame and having respective end-position and center-position stops juxtaposable and cooperating with the respective sensors in the respective positions of the roller frame on the support frame, and a controller connected between the sensors and the drive for operating the drive in accordance with the frame position detected by the sensors.
