Abstract: A device (1) for coating and/or impregnating a band (2) in continuous movement (3) with a liquid or pasty product, including an applicator (4) for depositing a layer (5) of the product, at least partially on one face (6) of the band. The device includes applicators (4) which are constituted by a reservoir (7, 70, 407) having a perforated area (8, 21,), brought into contact with the face (6) to be coated and/or impregnated, around which the band is deflected, having on a portion of its shell a set of orifices (9, 90, 409) opening externally and communicating internally with a product feed chamber (10, 110, 410), the surface and/or permeability of which are adjustable.
