ABSTRACT:
A guide apparatus for guiding a strip of material along a predetermined strip travel path and for centering the strip relative to the central axis of the travel path includes a pair of lever arms and a pair of strip engaging members spaced from one another and mounted on each of the lever arms. The lever arms are each supported for pivotal movement about a respective pivot axis centrally located between the rollers and are positioned relative to the strip travel path with the pivot axis of each lever arm extending in a direction perpendicular to a strip guiding surface and intersecting the central axis of the strip travel path. In addition, the lever arms are biased toward a pivoted position in which the strip engaging members mounted on the lever arms are adapted to engage a strip traveling along the strip travel path and center the strip relative to the central axis of the travel path.
