Device for applying a coating layer to a strip of continuously moving material

A device for continuously applying a coating layer on a strip of material travelling between two rotary cylinders bearing one against the other and having a rotational speed equal to the travelling speed of the strip, one of said rotary cylinders being an applicator cylinder applying the coating layer to the strip, comprising:

• a reserve containing a coating product,
• a take-up roller controlled in rotation for continuously taking from the reserve a specific amount of product,
• means for transferring the product taken by the take-up roller to said applicator cylinder, the transfer means including a second roller (10) situated between and extending parallel to the take-up roller (9) and the applicator cylinder (3) and bearing only against the applicator cylinder, and a third roller (11) bearing against the take-up roller and the second roller,
• first means for rotating the take-up roller at a constant preadjusted speed of rotation, and
• second means for rotating the second roller (10) in the same direction as the take-up roller, at a speed equal to the travelling speed of the strip (1), the third roller (11) being loosely mounted.
