<p>-A system for feeding a plurality of bristles in a circular arrangement, particularly for use in machines for forming circular brushes, comprises a drum (1) extending axially along its own axis (X1) and designed to form a plurality of axial channels (2a, 2b, 2c, etc.), each having a cross section in the form of a sector of a circle, in a circular arrangement with the corresponding vertices orientated towards the central axis (X1) of the said drum (1), and also a replaceable nozzle (B), positioned downstream of the said channels (2a, 2b, 2c, etc.) with respect to the direction of feeding of the bristles and designed to form an internal truncated conical cavity tapered from the upstream to the downstream end and having an outlet aperture (5). In order to change the maximum diameter of the circular arrangement of the bristles being fed, the said nozzle (4) is replaced with one having an outlet aperture (5) with a different diameter.</p> |
