    摘要： Paint recovery and cleaning trolley (3, 33) for an apparatus (1) for applying paint provided with a belt (2) for conveying pieces to be painted, comprising:
    - A paint recovery subunit (21), in its turn comprising:
    ▪ A reverse roller (19) in contact with the lower return section of said conveying belt (2), which recovers paint from the belt,
    ▪ A doctor blade (11) tangentially placed with respect to said reverse roller (19) for all its length, to allow the accumulation of a solvent and wetting said reverse roller (19);
    ▪ A doctor blade (14) scraping the reverse roller (19) so recovering paint;
    ▪ A doctor blade (10) scraping the lower return section of said conveying belt (2),
    ▪ At least one nozzle (13) for supplying a solvent compatible with the paint in use,
    ▪ A hopper (12) collecting said solvent, placed under said reverse roller (19),
    ▪ A paint collecting reservoir (130),

    - A cleaning subunit (22), in its turn comprising:
    ▪ A reverse roller (29) in contact with the lower return section of the conveying belt (2),
    ▪ A doctor blade (211) tangentially placed with respect to said reverse roller (29) for all its length to allow the accumulation of a solvent and wetting said reverse roller (29),
    ▪ A doctor blade (210) scraping the lower return section of said conveying belt (2),
    ▪ At least a nozzle (213) for supplying a solvent,
    ▪ A hopper (212) collecting said solvent, placed under said reverse roller (29),
    ▪ A solvent collecting reservoir (231),

    wherein in each subunit (21, 22) said components (19, 11, 10, 2; 29, 211, 210, 2) form a closed chamber having the shape of a triangular prism, of which said components (19, 11, 10, 2; 29, 211, 210, 2) represent the rectangular faces, said chamber containing said solvent, which slowly drips from the triangular faces of said chamber into a respective collecting hopper (12, 212).

    摘要： Apparatus (2) for applying paint to products, preferably to panels (4), using rollers, comprising at least the following components:
    - a device (5) conveying said panels, preferably in the form of a band conveyor;
    - a pair of rollers, a first dosing roller and a second applying roller for applying paint to said panels;
    - a control unit capable of detecting the parameters coming from the detecting systems of said apparatus and processing them, comprising
    - a paint tank (6) in its turn comprising a measuring device, preferably in the form of a load cell (7), capable of detecting the weight variation of the paint contained in said tank;
    - a detecting bar (3) for detecting the dimensions of said panels when passing, preferably placed before the entry of said panels into said apparatus (2).
