  • Paper rotation method and apparatus
    Patent number: 7766325
    Abstract: Apparatus for rotating a sheet moving in a first direction, the rotator comprising: at least one first roller that rotates against a sheet first side, the at least one first roller having a first drive; at least one second roller that rotates against the sheet first side, the at least one second roller having a second drive that is capable of rotating the second roller independently of the first roller, the second roller being spaced a distance from the at least one first roller in a direction perpendicular to the first direction; and a controller that controls the first and second drives to rotate the sheet around an axis substantially perpendicular to the plane of the sheet.
    Type: Grant
    Filed: June 16, 2004
    Date of Patent: August 3, 2010
    Assignee: Hewlett-Packard Indigo B.V.
    Inventors: Daniel Sagi, Aron Shmaiser, Avi Barazani

  • Tandem printing system with fine paper-position correction
    Patent number: 6823786
    Abstract: A tandem printer with a mechanism for fine substrate-position correction, comprising: a first printing station; a second printing station; a rotatable element, rotating at a given rotation rate, that receives the substrate after printing thereon by the first printing station and transfer the substrate toward the second printing station; a sensor which measure the position of an edge of the substrate during its transfer from the first printing station to the second printing station; and a controller, which applies a corrective step change in angular position of the rotatable element responsive to the measurements of the sensor, without changing the general rotation rate of the rotatable element.
