Claim:
1. A method to control section sizes of a rolled product in a segment of a rolling line, between at least two rolling stands each provided with its own drive members, in which between said two rolling stands a characteristic size of said rolled product is detected, and a control unit compares said characteristic size of the rolled product with a reference size, to which an optimal drawing condition corresponds, and acts on said drive members in order to hold the rolled product in said optimal drawing condition, wherein the method comprises: a first step of determining said reference size wherein said first step includes: a subsequent second step in which the control unit compares the characteristic size of the rolled product in transit, as detected by said detector, with the reference size; and a third step in which, if a deviation is detected between the characteristic size measured and the reference size, an action is carried out on at least one of said drive members in order to return the characteristic size of the rolled product to said reference size,
