Abstract

A process is claimed for planishing flat metal products (30) such as plates, sheets or strip. The product is passed between two assemblies of planishing rollers (5,51,53). The rollers (51) of one assembly being staggered in the direction of defilement (F) with respect to the rollers (53) of the other assembly. The two assemblies are spaced and positioned in such a manner that the product is subjected to a series of alternate flexions of decreasing amplitude. Compensation is made for the strain of the rollers provoked by the stresses imposed by the product on the rollers. This compensation is applied independently for each roller, in a manner that ensures that all the longitudinal fibres of the product are subjected to the series of bending deformations for which the amplitudes and the variations of the amplitude in the direction of defilement are essentially identical over the width of the product. The device used to put this process into service is also claimed.
