A distributor unit includes a reservoir (7) containing a liquid substance, an anilox cylinder (8) and a cliché cylinder (9) onto which is movably fitted a cliche jacket (18), the reservoir (7), the anilox cylinder (8) and the cliche cylinder (9) being movable from and to a cylinder (2) on which travels a web-shaped material (3) which has to receive the substance. The distributor unit has an operator side and a transmission side, the anilox cylinder (8) and the cliche cylinder (9) being held by corresponding supports on operator side (14, 15) and on transmission side (16, 17). A device (19) for locking the cliche cylinder in cantilever position when the corresponding cliche jacket (18) has to be substituted is associated to the support on transmission side (17) of the cliche cylinder (9). The support on operator side (15); of the cliche cylinder (9) includes a first and a second element (150, 151) automatically movable from and to the cliche cylinder (9). The elements in configuration of use hold the cylinder (9) on the operator side and, in a configuration of substitution of the cliche jacket (18), are reciprocally spaced disengaging the operator side of the cliche cylinder (9). |
