It is one of the most produced bamboo species in my country, characterized by its thin, hollow walls and high taper. In the initial processing of moso bamboo, the raw bamboo is first cut into desired lengths. This is typically done using a bamboo sawing machine to cut the raw bamboo into bamboo tubes (i.e., bamboo segments) of the required length. This sawing operation is called raw bamboo segmentation or raw bamboo length determination. Then, the piles of bamboo tubes are manually sorted (e.g., according to the tube shape). Wall thickness (Classify by specifications) and classify the same cylinder Wall Bamboo tubes of the specified size are fed into the corresponding bamboo splitting machine (also known as a bamboo splitting machine) for splitting, resulting in bamboo strips of a set width.
