A storage unit is described for the temporary storage of rolls (L) of rolled up band-shaped material, arranged between a first section (I) and a second section (T) of a production line and comprising: input means (25, 63) for the distribution in the storage unit of rolls (L) arriving, output means (29) for the controlled discharge of rolls from the storage unit, an indefinite flexible member (3) bearing a plurality of seats (19) for said rolls, said seats being subdivided into two groups, a first group of empty seats and a second group of full seats respectively, a first motor unit (23) for the advance of the seats of the first group towards the input means, and a second motor unit (27) for the advance of the seats of the second group towards the output means. The two motor units (23, 27) move the flexible member (3) with a continuous motion, and the speed of advance of the two motor units is determined respectively by the rate with which the rolls come from said first section (I) and the rate with which they are requested by said second section (T).
