Method for manufacturing resin-impregnated endless belt and a belt for papermaking machines and similar industrial applications
First Claim
1. A method for manufacturing resin impregnated endless belt structures, designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, said method comprising the steps of:
- a) providing a base substrate for the belt;
b) depositing sacrificial material onto said base substrate in a controlled manner so as to control the x, y, z dimensions of the material deposited to create a predetermined pattern of deposits, wherein each deposit comprises one or more droplets of sacrificial material and wherein said predetermined pattern creates a surface of said belt structures providing a functional aspect thereto;
c) depositing a functional polymeric resin material onto said base substrate to cover areas thereof not having said sacrificial material;
d) at least partially setting said functional polymeric resin material; and
e) removing the sacrificial material from said base substrate.

Abstract
A method for manufacturing resin-impregnated endless belt structures and belt structures designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, requires the application of a sacrificial material onto a base substrate in a predetermined pattern in droplets having an average diameter of 10μ (10 microns) or more. Polymeric resin material is then deposited on the base substrate to cover all areas except those on which the sacrificial material has been previously applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

47. A resin-impregnated endless belt structure, designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, said belt comprising:
-
a base substrate; a polymeric resin coating deposited on said base substrate; and a pattern of x, y, and z dimensionally controlled voids, formed in the polymeric resin coating by the removal of sacrificial material, wherein the belt is made in a manner comprising the steps of; a) providing a base substrate for the belt; b) depositing sacrificial material onto said base substrate in a controlled manner so as to control the x, y, z dimensions of the material to create a predetermined pattern of deposits, wherein each deposit comprises one or more droplets of sacrificial material and wherein said predetermined pattern creates a surface of said belt structures providing a functional aspect thereto; c) depositing a functional polymeric resin material onto said base substrate to cover areas thereof not having said sacrificial material; d) at least partially setting said functional polymeric resin material; and e) removing the sacrificial material from said base substrate. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
