<p>The invention relates to a device for forming fibre balls out of elongated fibres carried in an air flow. The device contains a stator chamber (1) which is fixed to a frame and which has a circular cross section, and coaxially within it there is arranged a rotor (2), also having a circular cross section, and being rotatable around its shaft (3), whereby the rotor has on its periphery a plurality of radial blades (12, 12') at mutual peripheral distances and at a short distance from the inner wall (1') of the stator (1) in order to form an annular intermediate space (14) extending over the axial length of the rotor between the inner wall (1') of the stator (1) and the blades (12, 12') of the rotor (2). Further, means (8-10) are fastened to the frame and functionally connected to the shaft (3) of the rotor for rotating the rotor, and moreover, the device contains an input opening (5) at one end of the stator chamber (1) and an output opening (7) at the opposite end of the rotor chamber (1) in order to remove and to separate from the air flow the fibre balls formed in the intermediate space (14). According to the invention the stator chamber (1) and the rotor (2) are substantially conical, and they can be mutually positioned in the axial direction in order to adjust the width of said intermediate space without having to remove the rotor (2) from the stator chamber (1) in order to adjust the blades (12, 12').</p> |
