The present document concerns a machine for continuous dyeing of leather items, wherein said leather items are passed through two opposite rollers (1, 2) rotating about mutually parallel rotation axes perpendicular with respect to the direction of forward motion of the leather item (P), in "synchronous" mode, i.e. with the same direction as that of forward motion of the leather item. Such a machine being characterised in that the two rollers (1,2) consist of two cylinders the outer surface of which is engraved/knurled, with the formation of pits or other cavities suitable for transferring a predetermined amount of a film (9, 10) of liquid dye product at the same time on the two surfaces of the leather aforementioned product (P1). |
