A rolling method adapted to a mill for rolling a strip (ST), comprising:
- rolling said strip using a pair of working rolls (WR) with parallel axes with said strip being taken between said working rolls (WR) and travelling between the pair of working rolls, each of said working rolls having at least one generatrix of contact with the strip,
- transmitting a rolling force to said working rolls (WR) using a pair of support rolls (SR), the rolling force being normal to the strip, said working rolls (WR) and said support rolls (SR) being situated on the same side of the strip being in contact with each other along a common support generatrix in order to transmit said rolling force,
- maintaining the at least one contact generatrix and the axes of said working rolls in a plane perpendicular to a direction of travel of the strip,
- holding of each of said working rolls (WR) by a pair of side support rollers (SSR), situated on either side of said plane perpendicular to the direction of travel of the strip, each of the side support rollers (SSR) being able to exert, along a bearing generatrix of said working roll (WR), a force holding an axis of the working roll (WR) in a given position with respect to a rolling cage of the mill and with respect to said side support rollers,
- supporting of each of said side support rollers by means of two rows formed by a plurality of rollers (G) mounted side by side, for holding the side support rollers (SSR) in a given position,
- supporting each of the two rows formed by said plurality of rollers (G), said supporting being provided by a bearing support (BS) carrying the two rows of rollers (G),
- wherein said bearing support (BS) is mounted pivotably by a support arm (AR) on an articulation axis (A1), the articulation axis (A1) being parallel to the support roll (SR),
- said providing a support including pivoting of the bearing support (BS) around said articulation axis (A1),
- wherein the support roll (SR) is carried by an axis support (AS) formed by chocks (Ep), or Maes blocks (MB) cambering the support roll,
- said axis support (AS) being fixed with respect to the axis of the support roll (SR),
- wherein dimensions of a first interspace (It1) defined between the side support roller (SSR) and the support roll (SR) and a second interspace (It2) defined between the strip (ST) and the assembly consisting of the side support roller (SSR) and the bearing support (BS) vary during rolling because of reductions in diameters of the support roll and working roll caused by wear and planing of the support and working rolls, and
- a readjustment step of adjusting the dimensions of said first interspace (It1) and of the second interspace (It2) by carrying out an adjustment of the dimension separating an axis (ASR) of said support roll (SR) and the axis (AssR) of said side support roller (SSR), said readjustment step being distinct and additional to the pivoting of the bearing support (BS) around said articulation axis (A1),
- wherein said bearing support (BS) is fixedly mounted removably on said support arm (AR), with an adjustable position on the support arm,
- wherein said adjustment of the dimension separating the axis of said support roll (SR) and the axis of said side support roller (SSR) implemented during the readjustment step is performed by a step of modifying the position of said bearing support (BS) on the length of said support arm (AR),
- said readjustment step being configured to change the dimension of the first interspace for a same first diameter of each of the working rolls (WR), a same second diameter of each of the side support rollers (SSR), and a same third diameter of each of the support rolls (SR), said first interspace being determined when said working roll (WR) is held by said pair of side support rollers (SSR).
