Abstract
This disclosure relates to a method of manufacturing a sign or similar article by providing a wooden substrate having an upper surface; providing a laminate formed by several plies including a ply of sandblast-resistant material, an adhesive, a ply of vinyl, another adhesive and a carrier ply; cutting the laminate to form a template of a desired configuration and applying the template to the upper surface of the substrate, sandblasting the upper surface of the substrate which removes an upper surface strata thereof which is exposed to the sandblast material while unexposed surface strata is uneffected, and thereafter removing the sandblast-resistant ply from the vinyl ply forms a permanent upper covering/indicia/design atop the selected area of the substrate unaffected by the sandblast material.
Claims32
A method of manufacturing an article comprising the steps of providing a substrate having an upper surface;
- providing a laminate having a peripheral edge of a predetermined profile and including a first ply adapted to become a part of the article and a second ply adapted to protect the first ply during the manufacture of the article;
- the predetermined profile of the laminate being defined by generally coextensive edges of the first and second plies, securing the first ply to the upper surface of the substrate;
- directing abrasive material against the second ply and an exposed surface portion of the substrate upper surface whereby the second ply protects the underlying first ply from the abrasive material and the abrasive material removes an upper surface strata of the substrate exposed surface portion without affecting the upper surface strata underlying the first ply, and removing the second ply from the first ply whereby the article includes the first ply in coextensive overlying relationship to the underlying upper surface strata of the substrate.
