  • Mechanism for retaining a stack of sheets in a compiler tray, such as for automatic stapling
    Patent number: 7624975
    Abstract: In a finishing apparatus, as would be used with a printer or copier, sheets to be stapled are accumulated in a compiler tray. A set of pivotably-mounted fingers are pressed, by their own weight, against a top sheet as sheets enter the compiler tray. The mount on which the fingers are mounted can be moved to accommodate a growing stack and maintain a parallel contact between the fingers and the top of the stack. The even distribution of pressure from the fingers avoids curling or buckling of the sheets in the stack prior to stapling.
    Type: Grant
    Filed: May 20, 2004
    Date of Patent: December 1, 2009
    Assignee: Xerox Corporation

  • Booklet maker with flexible gate upstream of crease rolls
    Patent number: 6939283
    Abstract: In a booklet maker or sheet folder wherein one or more sheets are pushed through a nip formed by a pair of crease rolls, a pair of flexible gate members cover the nip while sheets to be folded are being loaded. When the sheets are pushed through the nip, the flexible gate members are displaced, allowing the nip to receive the sheets. Following feeding of the sheets, the flexible gate members spring back to a closed position.
