Abstract: A guide frame has overlying support on a base frame and supports a pair of spaced, parallel guide rollers arranged with their axes extending across the line of travel of a moving web. These rollers receive the traveling web over the surface thereof from an entering span at one of the rollers and an exiting span at the other roller, the span between the rollers comprising a guide movement span. A fixed offset pivot supports the guide frame pivotally on the base frame in an area adjacent to the entering span of the rollers. This fixed pivot support is rigid in a direction parallel with the pivot axis but has some flexibility in the direction of travel of the guide movement span of the web. A movable pivot support supports the guide frame on the base frame in an area adjacent the exiting span of the rollers.
