摘要： One embodiment of the invention pertains to an automatic and precision guiding procedure and apparatus for thin narrow moving steel strip as the strip is collected in a looping or storage device made up of four rolls. One end of each of the rolls is rotatably supported in a stationary frame, while the opposite ends of the rolls are rotatably supported in an orbital mounted frame, the axes of rotation of the rolls being equal distance from the axis of rotation of the rotatable frame. Much activity in recent years has centered on developing and perfecting a means and method for automatically guiding moving material such as rolled steel strip, incident to the processing of the strip; for example, during its rolling, pickling, annealing, or plating. One of these activities has become generally known as the Lorig self-centering system for strip-like material, which system is covered by a number of U.S. patents, three exemplary ones being U.S. Pat. Nos. 2,593,157, 2,593,158, and 2,706,625. While such guiding systems have found employment they have not replaced the more conventional guiding procedure of employing edge engaging means for the moving strip. One of the reasons for the continuance of employment of edge guiding means is the additional cost involved in employing the automatic guiding means, even though such means offer the advantage of avoiding the strip physically coming into contact with the rigid edge guiding members of the conventional procedure.
