Mechanism For Substantially Preventing Trail Edge Smear Of An Image On A Receiver Member

US Patent:
5515147, May 7, 1996
Filed:
Oct 28, 1994
Appl. No.:
8/330504
Inventors:
Michael Kenin - Rochester NY
Steven L. Moore - Dansville NY
David P. Dworzanski - Walworth NY
Larry T. Schlitzer - Rochester NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
G03G 1514
US Classification:
355273
Abstract:
In an electrostatographic reproduction apparatus, a mechanism which substantially prevents trail edge smear of an image on a receiver member. The reproduction apparatus has a flexible dielectric web entrained over at least a pair of support members defining a web travel path. Successive areas of the dielectric web are adapted to respectively carry a marking particle developed image. A marking particle developed image is transferable from the dielectric web to a receiver member brought into contact with the dielectric web. After transfer of the developed image to the receiver member, the receiver member is transported away from the dielectric web. A mechanism is provided for facilitating separation of a receiver member from the dielectric web. The separation mechanism includes an elongated member having a surface adapted to enable the dielectric web to pass thereover. The elongated member is positioned to engage the dielectric web along a line of contact transverse to the direction of travel of the dielectric member along the web travel path, downstream of the transfer means and upstream of the transport means to separate the receiver member from the dielectric web closer to the transfer means, and dampen perturbations in the dielectric web, whereby trail edge smear of an image on a receiver member is substantially prevented.

Articulated Vacuum Transport Apparatus

US Patent:
5526105, Jun 11, 1996
Filed:
Dec 14, 1994
Appl. No.:
8/355799
Inventors:
Michael Kenin - Rochester NY
Steven L. Moore - Dansville NY
Larry T. Schlitzer - Rochester NY
David P. Dworzanski - Walworth NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
G03G 1500
US Classification:
355312
Abstract:
Apparatus for transporting sheets seriatim along a travel path from a first station to a downstream second station. The sheet transport apparatus comprises a housing in juxtaposition with the sheet travel path. A first transport assembly and a second transport assembly are respectively mounted within the housing. The second transport assembly is mounted in the housing, downstream in the direction of sheet transport, of the first transport assembly, for articulation relative to the first transport assembly, and so as to extend into operative relation with said sheet travel path for transporting a sheet respectively along a first portion of the sheet travel path and a second portion of the sheet travel path at an angle to the first portion.

Sheet Feeding Apparatus

US Patent:
5295676, Mar 22, 1994
Filed:
Nov 16, 1992
Appl. No.:
7/976609
Inventors:
Michael Kenin - Rochester NY
David P. Dworzanski - Walworth NY
Donald S. Hensel - Rochester NY
Raymond M. Quackenbush - Hilton NY
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
B65H 312
US Classification:
271 94
Abstract:
Apparatus for feeding material, in the form of discrete sheets, seriatim from a stack of discrete sheets. The sheet feeding apparatus comprises a support for a stack of discrete sheets. A sheet in the supported stack of discrete sheets is engaged by a friction mechanism for selectively removing such sheet from the stack. Such sheet is attracted to the friction mechanism by vacuum directed adjacent to the friction mechanism. The vacuum attraction increases the force of engagement of such sheet with the friction mechanism to facilitate removal of such sheet from the stack of discrete sheets by the friction mechanism.
