US Patent:

7171147, Jan 30, 2007
Filed:

Oct 14, 2004
Appl. No.:

10/965642
Inventors:

Steven O. Cormier - West Henrietta NY, US
Dennis J. Grabb - Sodus NY, US
Ralph E. Williams - Rochester NY, US
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

G03G 15/16
US Classification:

399308
Abstract:

A double-sleeved roller (DSR) including: a mandrel having a disconnectable end incorporating three termination plates having specified axial profiles; a replaceable inner sleeve member (ISM) mounted on the mandrel; and, a replaceable multilayer outer sleeve member (OSM) including at least one synthetic layer with the OSM surrounding the ISM. The mandrel, adapted to support a non-reinforced ISM, includes the termination plates joined together so as to define two sets of channels for selectively conveying pressurized air to either OSM or ISM for radial expansion thereof. The termination plates have specialized outer shapes, with each termination end plate including a cylindrical portion adjoining a tapered portion. For removal and/or replacement of the OSM or the ISM, a removable support member is moved away from the disconnectable end of the roller while the other end of the roller continues to be supported in cantilever fashion.

Web Cleaning Apparatus For Electrographic Printer

US Patent:

7548711, Jun 16, 2009
Filed:

Mar 31, 2006
Appl. No.:

11/394728
Inventors:

Francisco L. Ziegelmuller - Penfield NY, US
Thomas C. Bidwell - Bergen NY, US
Dennis J. Grabb - Sodus NY, US
Daniel R. Palmer - Rochester NY, US
Matthias H. Regelsberger - Rochester NY, US
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

G03G 15/20
US Classification:

399123, 399164, 399351
Abstract:

A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. A quick disconnect feature enables the cleaner cover to be de-coupled from the cleaner body to allow the debris to be easily removed with replacing the web-cleaner. The cleaner has a cleaner sump that is spring loaded to force contact of four strategically placed stops in the sump with a stationary back up shoe assembly allowing for higher precision of blade engagement with a transport web or a photoconductor. The web-cleaner has two wiper blades that are locked into the cleaner sump by springs, to facilitate dumping of material removed from the web without removing the cleaning blades. The sump has baffles molded into the sump to eliminate extra parts and has several features that enable easy attachment of the cleaning blades, a permanently attached foam seal around the perimeter of the cover and sump interface. The wiper cleaning blades and the cover assembly are easily replaceable by the operator.

Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

G03G 15/09
US Classification:

399273, 399343
Abstract:

A printer having a developer station for holding a supply of developer which includes magnetized carrier particles, a magnetized development roller, and an imaging roller proximate the development roller which collects carrier particles during operation of the printer. A scavenger proximate the imaging roller and the development roller removes the carrier particles from the imaging roller during operation of the printer which are then urged through a slot in the scavenger by the magnetized development roller.

Abstract:

A method of making a slotted scavenger wherein a rigid sheet is used as a starting material. A slot is formed through the sheet having horizontally angled sidewalls such that an opening of the slot on a first major surface of the sheet is smaller than an opening of the slot in a second major surface of the sheet. Modifications of the method include using a rotating cutting tool for cutting through the sheet to form slots.
