A method for producing a roll from printed products in a winding operation includes winding the printed products with winding tape onto a winding core; driving a winding rug with a first drive, wherein the winding rug is arranged on the underside of the winding core and fitted against the winding core for rotating the winding core; driving a winding tape supply with a second drive, wherein the winding tape is unwound from the winding tape supply; and maintaining a predetermined tape tension during the winding operation. Maintaining the predetermined tape tension includes measuring speed and distance with measurement devices at the first and second drives to obtain measured values, computing the diameter of the winding tape supply with the measured values, and regulating a rotational moment with the computed diameter of the winding tape supply to maintain the tension.
