Method and device to guide the strip between the stands in a rolling mill finishing train to roll thin strips of a final thickness in the order of 1.2 mm and less, the inter-stand device including at least a guide device arranged at the outlet of the upstream stand (11a), a looper unit (15) comprising at least a looper roller (20) and a guide device arranged at the inlet to the downstream stand (11b), the looper roller (20) having at least a lowered position at the step before the leading end of the strip enters and a plurality of raised positions, while the strip is passing through, to form the desired loop, the looper roller (20), at least when it is in the lowered position before the strip enters, being made to rotate at a tangential speed at least equal to the speed at which the strip is fed between the stands. The looper unit (15) comprises an empowered drive (21) associated with the looper roller (20) at least when the looper roller (20) is in its lowered position, the drive (21) being structured to make the looper roller (20) rotate, before the strip enters, at a tangential speed at least equal to the speed at which the strip is fed between the stands.
