A method for assembling a drum (2) built up of segments and forming part of the axle (1) for a brush roller wherein: a) each segment (7.1, ..., 7.4) is brought into alignment by the edge portion (42, 43, respectively) of a first shoulder (35) and/or a second shoulder (36) being brought into contact with the second (41) or first (40) contact surface of an adjacent segment (7.1, ..., 7.4); b) through-holes (45, 46) are drilled in radial direction through a first (35) and a second shoulder (36) in each segment (7.1, ..., 7.4), one o f said holes also being threaded; c) two (45, 46) or more holes (45, 46) are drilled in axial direction in each shoulder at equal or different distances from each other; d) an attachment element (47) is arranged at each hole (45, 46). The invention also relates to a drum (2) for a brush roller, said drum (2) being built up of at least two segments (7.1, ..., 7.4), each of which i s provided at its upper side (8) with two or more, preferably four, protruding beams (9.1, ..., 9.4), a U-shaped channel (10.2) being arranged between two adjacent beams (9.1, 9.2), and the drum (2) being arranged to rotate about i ts axis (12) by means of torque-transmitting means (50) connected to the drum (2), each segment (7.1, ..., 7.4) in the drum (2) being constructed with double walls with a rigidity sufficient for the assembled segments (7.1, ... , 7.4) to form a fully self-supporting drum (2). The invention also relates to an axle (1) for a brush roller, the axle (1) consisting of a drum (2) as described above, which is arranged between two shaft ends (3, 4), each shaft end (3, 5) being connected to a torque-transmitting plate (50) arranged concentrically in relation to and connected to the end part (22) of the drum (2).
