ABSTRACT:
As heretofore manufactured, straightening machines have incorporated chain and sprocket drives and the straightening rolls have been geared together so as to rotate in unison. At high speeds the problems of lubrication on the plain roll bearings and as regards the chains and sprockets become increasingly more difficult. By using flexible belts and more particularly timing belts for driving the rolls of the straightening machine, the belt drive system of the invention eliminates the gears and also the speed reducing units as previously employed. Countershafts are driven from the drive motor by one or more flexible belts and other flexible belts are employed for driving the pinch rolls and the lower straightening rolls from the said countershafts.
