The surface of the mandrel 21 of the paint cutting unit 20 is damaged by the contact with the cutter 22, and the position of the damage moves every time the length of the container barrel to be cut changes, so that the surface of the mandrel 21 can be spread anywhere. become.
When the mandrel 21 is deeply scratched, when the tube A is cut, the back side of the tube A pushed by the cutter 22 is pushed into the scratch on the surface of the mandrel, so that the cutting edge of the cutter 22 cannot cleanly cut it. The cut part of the container body is poor in appearance. Therefore, mandrel 2
1 has a short life, and the blade edge of the cutter 22 is significantly worn. Further, in the above-described conventional apparatus, it is necessary to separately provide the printing unit 10 and the paint separating unit 20, install the mandrels 11 and 21 in each, and transfer the printed tube A mounted on the mandrel 11 to the mandrel 21. Therefore, the productivity is poor and the entire apparatus becomes large. In order to solve this problem, the printing unit 1
0 and the paint separation unit 20 are integrated, and even if the mandrel is used in common, a scarred mandrel causes color spots on the printed surface of the tube during printing, which impairs the commercial value of the container barrel. Become.

い。The cutter 2 has an air cylinder 3 so that when the blade edge of the cutter 2 is brought into contact with the tube A, the blade edge of the cutter 2 has the same bite amount as the thickness of the body portion of the tube A.
Is adjusted, and the pressing force of the air cylinder 3 is adjusted so that the pressing force between the cutting edge of the cutter 2 and the tube A at that time is 2.0 Kg / cm 2 or less. Cutting edge and mandrel 1 cemented carbide layer 5
Even if they contact with each other, the cemented carbide spray layer 5 is not scratched by sliding on each other at the contact portion, and the cut surface of the tube A is cut into fine pieces. Since the carbide spray layer 5 of the mandrel 1 is not scratched,
Since printing can be performed with the same mandrel 1 without any trouble, it is not necessary to separate the printing unit and the paint separation unit, install a mandrel on each, and transfer the tubes after printing, as in the past, and integrate them. It is possible to downsize the device and improve productivity. Furthermore, since the cemented carbide layer 5 only needs to be applied to the contact portion of the mandrel 1 with the cutter 2, the weight of the mandrel does not become heavy, and it is not necessary to enlarge the power system for driving.
