The device for washing the inking mechanism of a rotary printing machine, specifically for washing the ink transferring canvas cylinder, the ink recovery container, the doctor blade chamber and the various ducts of the inking mechanism, comprises washing means for washing the various ducts of the inking components associated with washing means fitted between two lateral jaws (9 and 10) and consisting of a distributor (14) provided with nozzles (16 to 18), the distributor (14) being fitted pivotable in a strap (13) which is shiftable laterally between the two jaws (9, 10) with a reciprocating movement along the inking components to be washed. The angular position of the distributor (14) is reversed every time the strap (13) reaches the end of its lateral stroke by simple contact of the nozzles (15, 16, 17) with a stop (31). The strap (13) is moved laterally by means of a linear pneumatic cylinder (21) located between the lateral jaws (9, 10).
L'invention concerne un dispositif servant à nettoyer le mécanisme d'encrage d'une machine à imprimer rotative, plus particulièrement à laver le cylindre de transfert en toile, le contenant de récupération de l'encre, le logement de la racle et les diverses canalisations du mécanisme d'encrage. Le dispositif comprend des moyens de lavage des diverses canalisations des composants d'encrage associés à des moyens de lavage intercalés entre deux mâchoires latérales (9 et 10) et comprenant un distributeur (14) doté d'ajutages (16 à 18), le distributeur (14) pivotant dans une courroie (13) qui peut se déplacer latéralement entre les deux mâchoires (9, 10) avec un mouvement alternatif le long des éléments d'encrage à laver. La position angulaire du distributeur (14) est inversée chaque fois que la courroie (13) atteint l'extrémité de sa course latérale par simple contact des ajutages (15, 16, 17) avec une butée (31). La courroie se déplace latéralement au moyen d'un cylindre pneumatique linéaire (21) placé entre les mâchoires latérales (9, 10).
