Method of producing ribbed board and product thereof

摘要

A method of producing a ribbed board product (8) from a mat comprising a material selected from a group consisting of wood-based materials, agricultural fibres, and synthetic fibres including adhesive and formed by compressing and curing a mat of the material under heat and pressure between a die. The die has a ribbed configuration with at least two outer zones (11) and at least two angled zones (12). The method further includes closing the die to form a die gap, wherein the die gap of at least two of the outer zones (11) is less than the die gap of at least two of the angled zones (12). The mat is consolidating under pressure and heat to form the ribbed board product.
