The laminated timber is made of small diameter material as raw material, and is cut into a plate by a log, dried by a plate, made into a square bar, cut off, selected, fingered, spliced, and subsequently processed to have a certain width. Thickness, length of wood. It is a new type of substrate used in the construction industry, furniture and decoration industry. It has high strength, 1.5 times of natural solid wood, good fireproof performance and high insulation performance. The specific production process is as follows:
(1) Processing of round logs into sheets: the round logs are cut into sheets by the sports band saws and the main small band saws.
(2) Drying of the board: mainly by fumigation, the moisture and oil in the wood (mainly the pine oil in the pine) are baked out, because the wood of the small diameter is prone to cracking and deformation, so after drying and dehydration, the thickness is natural. Reduce and crack and other reasons.

(4) Material selection and material breakage: The cut wood strips are screened, and the wood strips without missing materials, no blue change, no oil line, no cracking and no knot are cut into 200-700 mm or less. length.
(5) Finger joint: the wooden strips are made to be toothed and joined with strips by adhesive.
(6) Planing four sides: After four sides of the planer, the wood strips that have been picked up are arranged into neat squares.
(7) Panel: The specification strip is pressed into the required sheet by a press.
(8) Planing and sanding: the pressed sheet is pressed and sanded to the required thickness.
(9) Repair, finishing, and packaging.
