A pulley having a special outer contour particularly adapted to establish self aligning of narrow width belts rotating thereon. The outside diameter of the pulley is gradually crowned from each end with a more sharply crowned ridge located at the center intermediate the ends of the pulley to provide a compound crowned contour.

Belt pulley

The dimensions of a product passing through the finishing block of a roll rolling mill are measured. Where the dimensions of the product exiting the last finishing stand are out-of-tolerance, a calculation is made to determine the extent to which the roll parting of the work rolls of one of the two last finishing stands must be adjusted to bring the product into tolerance. Based on the calculated adjustment, progressively smaller adjustments are made to the roll partings of the work rolls of the upstream finishing stands to distribute the work which must be performed on the product to bring the product into tolerance.
