The bamboo flattening machine consisted of nine modules of flatteners made of high carbon steel shafting that were shaped from half round to flat with decreasing radii of curvatures using a lathe machine. Particularly, the bamboo flattening machine comprising main frame support having spaced and adjacently arranged series of variable-shaped adjustable roller modules with complementary upper rollers and lower rollers and each roller modules having different radii of curvatures that decreases towards that begins from half round into nearly flat-shape. A secondary frame support disposed adjacent said main frame support having retainer rollers adapted to maintain the flattened shape of the bamboo. The roller modules and retainer rollers being driven by gear motor through chains and sprockets assembly.
