    • PURPOSE: To facilitate the manufacture of a rectangular bamboo board through the cutting of the round bamboo material and extend the application for the building and floor material by rectangularly cutting a bamboo piece made by vertically cutting bamboo material to the elongated direction. CONSTITUTION: A bamboo material 1 is cut to form a plurality of vertically cut pieces 2. A bamboo whose stem hypodamic portion is thick is preferably used for bamboo material 1. The vertically cut pieces 2 are rectangularly cut to form a bamboo board. It is advisable from the yield rate viewpoint that when rectangularly cutting the bamboo material, the long side thereof is in contact with the inner circumference of the bamboo material 1 so that the external skin may not remain on the bamboo board 4 since the vertically cut piece 2 is bent like an arc. The surface of the bamboo board 4 is ground and finished to remove the outer skin because said skin becomes discolored with elapse of time. Since the bamboo board 4 is made of hypodamic portion with many vascular bundles, it has strength, fragility-resistance, bend-resistance, corruption-resistance, durability and waterproof characteristics.

    • PURPOSE: To facilitate analysis, extraction and resolution of the useful ingredient contained in each layer of a bamboo stalk by grinding succulent section of said stalk with a grinder and separately taking the powder for each cuticle section, hypodermic section and succulent section thereof. CONSTITUTION: A bamboo stalk mainly comprises three layers; a blue-green cuticle section, a yellow-white hypodermic section and white succulent section containing many vascular bundles in the order from the outside of said stalk. Each layer contains different types of useful ingredients and they can be separately taken out by each layer with a grinding means. It is recommended that the bamboo stalk be ground by a paper grinder. Different sizes of bamboo powder particle can be taken depending on the particle size of the paper grinder. The grinding depth depends on the thickness of each layer. To this end, the thickness of the bamboo stalk to be ground is measured prior to its grinding and a paper grinder is set to have the required grinding depth matched to the measured thickness. The ground bamboo powder is taken by an aspirator.
