Abstract: A spreader roll comprising at least one actuator and a stationary and most advantageously curved spreader-roll axle (10) on which there are roll segments (6, 7 and 8) which roll segments are connected to each other with flexible connector members (11) in connection with shell sleeves (1) so that the roll-segment shell sleeves rotate bearing-mountedly around the spreader-roll axle, in which at least one roll segment (8) is an actuator which operates most advantageously as a drum motor rotating the roll-segment shell sleeves (1) around the spreader-roll axle.
