摘要：
The subject of the invention is a leveller in which at least the first five rolls from the entry of the leveller have a radius/centre-to-centre spacing ratio identical to that of conventional levellers, in which at least the last five rolls from the entry of the leveller have a radius/centre-to-centre spacing ratio close to that of a decurler, and in which the centre-to-centre spacing between the intermediate rolls of the leveller is advantageously increased.
