Abstract
A method and apparatus for rolling a taper in or out of a strip during reduction by a rolling mill, rolling a first portion of the strip by employment of a gaugemeter roll gap control system using a first value for the mill stretch above the natural mill stretch value for the mill and which value during the rolling of the first portion will be a fixed value, thereafter rolling a second portion of the strip in the same rolling operation by using a value for the mill stretch in the gaugemeter roll gap control system which will vary to effect a change in the roll gap and hence a change in reduction of the strip in which the second value may be a linear function.
