PROCESS FOR PRODUCING SMOOTH STRAND-BASED SIDING OR STRUCTURAL OSB PANELS
20230264383 · 2023-08-24 ·

A process for producing a smooth-sided strand-based siding or wood structural panel using a pre-telegraphing process. The pre-telegraphing is performed after the primary process completes pressing and consolidation of the substrate/board. The pre-telegraphing process applies a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface. This may then be followed by lamination of overlay(s). The process is completed by post-lamination treatment and coating of the board.
