Description

[Detailed description of the invention] The present invention relates to an apparatus for manufacturing disposable chopsticks.

Disposable chopsticks are generally made from strip-shaped rotary wood that is cut from the outer periphery of a piece of wood in a peeled shape, so the split line between the chopstick pieces and the cracks that form at the base of the chopsticks when split by hand. The direction of the eye does not necessarily match, and the phenomenon of diagonal tearing occurs frequently during use. Therefore, as shown in Figure 1, if a sliced board obtained by cutting a piece of wood W into oranges and slicing it with a saw or cutting blade as shown by the chain line is used as a raw material, it will be possible to split the wood into oranges naturally. Disposable chopsticks extending in a direction substantially parallel to the grain direction are obtained, and the diagonal tearing phenomenon described above is drastically reduced.
