Abstract
A guide apparatus for a continuously moving web has an upstream fixed roller and a downstream fixed roller substantially parallel to each other and defining a plane. A fixed and substantially closed box carries these rollers and a frame which is offset from the plane and pivotal on the box about a frame axis substantially perpendicular to the plane. A pair of adjustment rollers are rotatable on the frame about parallel adjustment-roller axes fixed relative to each other and to the frame. Thus a continuously moving web can pass along the path over the upstream roller, then over one after the other of the adjustment rollers, and finally over the downstream roller. A sensor is mounted on the box adjacent the downstream roller and is connected via a control means to a motor inside the box that automatically pivots the frame whenever the web position detected by the sensor deviates from a predetermined desired position. Thus all of the critical circuitry and moving parts of the apparatus are safely within the closed box.
