Apparatus for functionally regenerating a brush for washing a flexographic plate

1) A cleaning apparatus (10) for functionally regenerating a brush (20) which can be used to wash a flexographic plate, said brush (20) comprising a cylindrical core (5) about which a channel (4) supporting filaments (3) is fixed according to a spiral shape, characterized in that it comprises:

• a frame comprising at least two supports (11,12) adapted to define a rotation axis (100) for said brush (20);
• a motorized assembly (60), which can be operatively connected to an end of said cylindrical core (5) of said brush (20) to rotate it about said rotation axis (100);
• a cleaning unit (30) comprising a carriage (31), movable along a rectilinear guide (32) and a tool (33) provided with an end (33A) adapted to penetrate into the spaces defined between the turns of said spiral to detach the polymer and monomer residues hardened in said spaces as a result of the use of said brush for said washing,
• wherein said guide (32) is configured so as to force said carriage (31) to move, due to the spiral shape of said channel (4) and as a result of the rotation of said brush (20), along an advancement direction (101) substantially parallel to said rotation axis (100) of said brush (20).
