Patent number: 6884205Abstract: A non-marking web conveyance roller has a generally irregular surface with a plurality of rounded up features that promotes superior venting of entrained air. The surface finish of the roller, formed by a thermal spray process, prevents the formation of impression and honing defects on the conveyed web.Type: GrantFiled: October 2, 2001Date of Patent: April 26, 2005Assignee: Eastman Kodak CompanyInventors: Gary L. VanNoy, Brian S. Rice, Fernando Ramos, Jr., Daniel C. Lioy

Patent number: 6583936Abstract: Disclosed is a form comprising a surface having a morphology of complex lenses wherein the surface asperities have an amplitude of between 1 and 40 micrometers, a spatial frequency of between 1 and 100 complex lenses per square millimeter, and between 1 and 40 minor lenses per major lens. Also disclosed is a method for making such a form.Type: GrantFiled: March 11, 2002Date of Patent: June 24, 2003Assignee: Eastman Kodak CompanyInventors: Cheryl J. Kaminsky, Robert P. Bourdelais, Steven M. Pratt, Daniel C. Lioy

Patent number: 6524660Abstract: A coating method and apparatus are taught for coating a liquid composition onto a surface of a moving web. A coating hopper for delivering the liquid composition to the surface of the moving web is provided with a rotatable backing roller. The moving web is wrapped around a portion of the rotatable backing roller with the rotatable backing roller supporting the moving web through a dynamic wetting line. The rotatable backing roller includes a plurality of circumferential grooves therein at a groove pitch of at least two per millimeter. An electrostatic field generated across the gap between the moving web and the liquid composition immediately prior to the dynamic wetting line. The method and apparatus permit either coating at a higher speed or higher viscosity than may be achieved in the prior art, or greatly reduced groove line nonuniformity at a given coating speed and viscosity.Type: GrantFiled: March 5, 2001Date of Patent: February 25, 2003Assignee: Eastman Kodak CompanyInventors: Robert R. Quiel, Fernando Ramos, Jr., Daniel C. Lioy, David A. Wakefield, Mark C. Zaretsky

Patent number: 4977656Abstract: A roller for conveying a web is manufactured by applying a layer of nickel to a steel roller and blasting the surface ofo the nickel layer with steel shot to create on the surface a deep texture with well rounded down features and sharp up features with peaks. The blasted surface is finished with a grinding action for removing the peaks to produce plateaus surrounded by interconnected channels. The interconnected channels of the surface allow air entrained between the roller surface and a web to be vented through the channels while the web is in contact with the roller.Type: GrantFiled: August 28, 1989Date of Patent: December 18, 1990Assignee: Eastman Kodak CompanyInventors: Daniel C. Lioy, Edward F. Hurtubis, Edward R. Schickler

Patent number: 4970768Abstract: A stainless steel roller for conveying a web has a surface prepared by blasting the surface of the roller with steel shot to create on the surface a deep texture with well rounded down features and sharp up features with peaks. The blasted surface is finished with a grinding action for removing the peaks to produce plateaus surrounded by interconnected channels. The interconnected channels of the surface allow air entrained between the roller surface and a web to be vented through the channels while the web is in contact with the roller.Type: GrantFiled: October 25, 1989Date of Patent: November 20, 1990Assignee: Eastman Kodak CompanyInventors: Daniel C.

Patent number: 4964203Abstract: An aluminum roller for conveying a web has a surface prepared by blasting the surface of the roller with steel shot to create on the surface a deep texture with well rounded down features and sharp up features with peaks. The blasted surface is finished with a grinding action for removing the peaks to produce plateaus surrounded by interconnected channels. Then the surface is hardcoated and polished. The interconnected channels of the surface allow air entrained between the roller surface and a web to be vented through the channels while the web is in contact with the roller.Type: GrantFiled: October 25, 1989Date of Patent: October 23, 1990Assignee: Eastman Kodak CompanyInventors: Daniel C.
