Abstract
PURPOSE: To cut a paper tube without causing crack and fracture in a surface treatment layer by cutting the paper tube surface treatment layer by a grinding blade and by cutting the exposed paper tube main body layer by a cutting blade. CONSTITUTION: A grinding blade 5 is pushed against a rotating paper tube 1 and a synthetic resin layer 12 or the surface layer of the paper tube 1 is cut off by the blade 5. Secondly, a cutting blade 4 with an edge angle β which is smaller than the edge angle αof the grinding blade 5 is pushed against the main body layer 11 of the paper tube 1, which is exposed by the cutting of the synthetic resin layer 12, and cut it by such a method as pushingly cutting the paper tube 1. This cutting method can dispense with any crack and fracture in the surface treatment layer 12.
