Abstract
An installation for rolling a flat product, comprising a support stand composed of two spaced uprights between which is placed a plurality of superposed rolls, between which a squeezing force is applied, for rolling a product (B) passing between two work rolls (A, A'). At least one of the work rolls (A) consists of a tubular jacket mounted for rotation about a stationary central shaft along which is provided a plurality of spaced bushes, isolated from one another. The work roll is associated with a feed circuit for circulating pressurized oil in order to form an oil film between each bush and the jacket. The pressure of the oil film between each bush and the corresponding zone of the jacket is individually adjusted for the application of radial forces of adjustable intensity per bush.
