ABSTRACT:
A method and apparatus for controlling the gauge of a product, such as for example a rod or bar, as the product is passing from an upstream roll stand to a finishing block. The product is rolled under tension between successive sizing stands arranged between the upstream roll stand and the finishing block. Variable loops are introduced in the product between the upstream stand and the first sizing stand as well as between the second sizing stand and the finishing block. Cross sectional dimensional measurements are taken of the product emerging from the second sizing stand, and signals representative of such measurements are employed by a controller to vary the product tension between the sizing stands in order to correct off gauge conditions in the product emerging from the second sizing stand.
