DEVICE AN DMETHOD FOR DISPENSING FIBRES

摘要

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.
