Abstract
A substrate for an endless belt in a papermaking machine comprising a plurality of preformed layers coated or impregnated with a polymeric or rubber material. Each preformed layer may be a textile material. At least one layer contains a matrix of preformed reinforcing components. The individual layers are first coated with a polymer resin or rubber material and then combined/stacked and cured/bonded to form the substrate of the belt.

A method of making a substrate of an endless belt to be used in papermaking applications comprising the steps of:
- a. coating or impregnating at least one layer of a plurality of layers of a material, at least one of which contains a reinforcing material, to form a preformed coated or impregnated layer;
- b. combining the coated or impregnated layers to form a structure;
- and c. processing the structure to form a laminate.
A method of making a substrate of an endless belt to be used in a papermaking application comprising the steps of:
- a. combining preformed layers of a material containing a matrix of a prepolymer and a curing agent to form a structure;
- b. processing the structure to form a laminate;
- and c. curing the structure.
A method of producing a papermaker's process belt comprising the steps of:
- coating or impregnating at least one layer of a plurality of layers of a preformed material with a polymer resin or rubber material, wherein at least one layer includes a reinforcing component for stability in a machine direction (MD) or a cross-machine direction (CD) of the belt;
- combining the layers to form a substrate or base substrate;
- and forming the substrate or base substrate into an endless belt.
