Abstract
Method and apparatus for guiding a strip traveling along a selected path past a first location on the path and then past a second location on the path, which method and apparatus comprise correcting the camber of the strip at the first location toward a first guide point, sensing the amount of correction at the first location, correcting the camber of the strip at the second location toward a second guide point, sensing the amount of correction at the second location and adjusting the first guide point based upon the relationship between the amount of correction at the first and second locations. In addition, there is provided an improvement in a strip guiding system for adjusting the phase lag between spaced guiding locations based upon a variable length of strip between the locations.
