A textile fibre band opening cylinder rotates within a cylinder having an inlet, and discharging separated fibres through a suction-aided outlet. The discharging fibres (2) are aligned in parallel especially by comb (14) grooves located on the outlet separation edge (13) The comb grooves (16, 17, 18) are essentially triangular or square, or have a radius of at least 4 mm. The grooves (18) extend as far as the fibre release point (10) and are fed by an air inlet (20).
