A device ( 10 ) and a method for dispensing fibres into concrete or similar material comprises a container ( 11 ) with an essential cylindrical shape. The container ( 11 ) has a bottom ( 13 ), an inner side ( 14 ) having a height ( 15 ) and a spiral path ( 12 ) arranged to the inner side ( 14 ). A first end of the spiral path ( 12 ) is arranged close to the bottom ( 13 ). The spiral path ( 12 ) has a width ( 18 ) that increases with the height ( 15 ) from the bottom ( 13 ) to the top of the container ( 11 ). The angle of inclination for the spiral path ( 12 ) decreases with the height ( 15 ) from the bottom ( 13 ) to the top of the container ( 11 ). The method comprises supplying the fibres into the container ( 11 ), vibrating the container ( 11 ) for feeding the fibres along the spiral path ( 12 ) and feeding the fibres continuously from the device ( 10 ) to the concrete.
