METHOD OF MAKING COMPOSITE FACE DECORATIVE BOARDS Russian patent published in 2013 - IPC B27M3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to agriculture. Hardwood is selected in whatever composition and dried at 30-90°C for 14-30 days to moisture content of 6-9%. Dried timber is subjected to butt-end reducing to make 50-60cm-long different-diametre billets. Different-shape moulds are filled by made billets in arbitrary order and poured with fast-curing resin to fill all cavities between billets without air gaps. Note here that resin is premixed with different dyes and moulds are held unless hardening of resin. Blanks are removed from moulds and cut across fibres to plates to be used for gluing on solid substrate or used directly without gluing onto whatever substrate. Note here that glue used contains no water while gluing is carried out in clamp carrier. Thereafter, board is finished at grinding-and-polishing machine and coated with water-resistant lacquer applied in several layers, every layer being dried.

EFFECT: reduced labour input, ease of manufacture, higher efficiency.
