The invention relates to a device for plate changing in which, by means of a roller (1), the angled rear edge (3) of a printing plate (2) can be inserted into the tensioning device (31) of a plate cylinder (14). Said device is intended to be of simple construction, to take up little space and to impair access to the printing unit as little as possible. This is achieved in that the roller (1) is held at its ends in guides (5, ...) and is displaced by actuating elements (8, ...), said actuating elements (8, ...) being permanently connected to the printing press frame, with the roller (1) pressing in the insertion direction against the rear edge (3) of the printing plate (2). A further development of the invention provides that the roller (1) is removable, without tools and by a manual operation, from the bearings.
L'invention a trait à un dispositif permettant le remplacement de plaques dans lequel, grâce à un rouleau (1), le bord arrière incliné (3) d'une plaque d'impression (2) peut être inséré dans le mécanisme de tension (31) d'un cylindre porte-plaque (14). Le dispositif est facile à fabriquer, prend peu de place et entrave le moins possible l'accès à la presse à imprimer. En effet, des guides (5, ...) retiennent les extrémités du rouleau (1), qui est déplacé au moyen d'éléments actionneurs (8, ...) fixés de façon permanente au bâti de la presse à imprimer, le rouleau (1) exerçant une pression dans le sens de l'insertion contre le bord arrière (3) de la plaque d'impression (2). Il est également possible de dégager le rouleau (1) des roulements sans outils ni effort manuel.
