Abstract
The invention relates to an apparatus and method of making a solid film. Viscous material (163) is input into a nip between a patterned roller (165) and a belt (167). The nip between the patterned roller (165) and belt (167) is facilitated by a compliant roller (169). Accordingly, a film may be produced that has discrete optical elements and a smooth backside.
Claims11
A compliant pressure belt comprising an endless belt comprising at least one elastomeric layer and one metal layer, wherein the outside surface of said belt has a roughness average less than 50 nanometers and a hardness between 90 Shore A and 50 Shore D, wherein said at least one elastomeric layer comprises a first elastomeric layer and a second elastomeric layer;
- said first elastomeric layer and said second elastomeric layer differ in hardness;
- and said first elastomeric layer is toward the inside of the belt in relation to the second elastomeric layer.
A compliant pressure belt comprising an endless belt comprising at least one elastomeric layer and one metal layer, wherein the outside surface of said belt has a roughness average less than 50 nanometers and a hardness between 90 Shore A and 50 Shore D, wherein said at least one elastomeric layer comprises reinforcing fibers substantially oriented in one direction.
