Reinforcement mesh for architectural foam moulding

摘要

A reinforcement mesh, an architectural moulding reinforced by the mesh, and methods of making the architectural moulding and the mesh. The mesh is adhered by an adhesive to the architectural moulding. In the mesh, weft yarns bend relative to warp yarns to conform to and against a curved profile of the architectural moulding, and the warp yarns are unbent and adhered against the moulding.

1. A reinforcement mesh to bend and conform to and against a curved profile of curved architectural features on a longitudinally straight architectural moulding, comprising:
bendable polymeric weft yarns in the reinforcement mesh joined with a pair of substantially straight fiberglass warp yarns in a hurl leno weave, wherein each individual fiberglass warp yarn in the pair have a higher tensile modulus than the polymeric weft yams of a second material substantially stiffer than the first material, an adhesive on the reinforcement mesh to adhere the reinforcement mesh to directly contact the curved profile having reversely curved surfaces, outside corners and inside corners, respectively, wherein the bendable polymeric weft yarns are smaller in yield sizes than each individual fiberglass warp yarn in the pair of fiberglass warp yarns, such that the polymeric weft yams are thinner and weaker, and readily bend relative to the fiberglass warp yams, wherein the adhesive is a soft ductile adhesive, and the fiberglass warp yarns and the polymeric weft yams are coated with a ductile, low elastic modulus binder material, for the polymeric weft yams to be bendable relative to the substantially straight warp yams with limited elastic strain and wherein the bendable polymeric weft yams and the binder material are bendable to have reversely curved surfaces, outside corners and inside corners, respectively, against the curved profile, and are bendable relative to the substantially straight fiberglass warp yams with limited elastic strain to prevent release of the adhesive from direct contact from the curved profile while the substantially straight fiberglass warp yarns extend substantially straight against the longitudinally straight architectural molding.
