Abstract
The longitudinally transported strip passes and is pressed between two cooperating transport rollers. The rotation axes of the two rollers are normally parallel to each other. One roller is swingably mounted about a swing axis which intersects and is perpendicular to the rotation axis of the other, non-swingable roller. Edge sensors are displaced by the lateral edges of the transported strip, when the strip improperly shifts transversely. The force thusly exerted upon an edge sensor is transmitted, via a force-multiplying lever system, to the swingable transport roller, swinging the latter to a position such that the swung transport roller exerts upon a major surface of the transported strip a force whose transverse component is directed opposite to the direction of the improper transverse shift, resulting in automatic recentering.
