Method of laminating articles
First Claim
1. A method of laminating a cover sheet to a substrate, comprising the steps of:
- inserting said substrate into a press;
inserting said cover sheet into said press over said substrate;
then injecting liquid thermoset polymer into said press;
applying heat and pressure into said press forcing said liquid thermoset polymer against said cover sheet and forcing said cover sheet against said substrate;
allowing said liquid thermoset polymer to cure under heat and pressure forming an at least partially cured silicone rubber sheet;
removing said substrate and said cover sheet from said press; and
removing said at least partially cured silicone rubber sheet from said cover sheet;
whereby said cover sheet is laminated to said substrate through the force of pressure from said liquid thermoset polymer.

Abstract
A method of laminating a sheet or sheets to a substrate and a method of laminating a plurality of articles. The substrate is inserted into a press. The sheet is inserted into the press over the substrate. Liquid thermoset polymer is injected into the press. Heat and pressure are applied forcing the liquid thermoset polymer against the sheet and forcing the sheet against the substrate. The liquid thermoset polymer is allowed to cure under heat and pressure forming a cured silicone rubber sheet. The cured silicone rubber sheet is removed from the press. A plurality of articles may be laminated by laminating the second of the articles while the first article is cooling.
