Patent ID: 7703393

Claim:
A device for adjusting a contact pressure exerted by each of a plurality of rollers on an adjacent rotational body in a printing couple comprising: a plurality of first rollers, each of said first rollers being supported in said printing couple for rotation about a roller longitudinal axis and having first and second roller ends, a first roller circumference and a first roller weight; an adjacent rotational body having a rotational body circumference and being engageable by at least selected ones of said plurality of first roller circumferences; a separate roller strip formed by said engagement of each of said selected ones of said plurality of first rollers with said rotational body circumference, each said separate roller strip having a circumferential width in a rotational direction of said at least first roller; a separate designator usable to identify each one of said separate roller strips; a separate support bearing for each of said first and second ends of each of said plurality of first rollers; a roller mount in each said separate support bearing, each said roller mount being shiftable radially in said associated separate support bearing; a plurality of actuators interposed between each said separate support bearing and each said associated roller mount, each of said plurality of actuators for each said roller mount being adapted to exert radial forces on said roller mount, said plurality of actuators each being usable to impart a controllable contact pressure which is exerted by each of said first and second ends of said selected ones of said plurality of first rollers to form each said first roller strip during operation of said printing couple; a unique identifying element for each of said actuators for each of said separate support bearings for each of said plurality of first rollers; and a control unit having a display device, said control unit being adapted to select each of said plurality of actuators for each said support bearing using said unique identifying element and said separate roller strip designator and to adjust and to control each of said plurality of actuators in each said separate support bearing independently of additional ones of said actuators in each said separate support bearing to vary said circumferential width of each said roller strip identified by each said separate roller strip designator during said operation of said printing couple, each of said actuators being activatable remotely by said control unit, said display device being adapted to selectively display said controllable contact pressure for each of said selected ones of said plurality of first rollers against said adjacent rotational body.
