Title: Apparatus and method for cutting-off container
Inventor: NISHIHARA HIDETOSHI
IPC: B23D25/14
Filed: 2001-08-28
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that, if once a cutting groove traces an approximately helical locus, a disk shape cutter 15 always traces that helical cutting groove and never draws a circular locus on the same periphery even if the cut-off operation is performed a number of times after that, and the cut-off of a container becomes impossible by the same apparatus. SOLUTION: The apparatus is provided with a rotary table for fixing an electric compressor and turning it about a vertical axis of a container, and a plurality of disk shape cutters for oppositely coming into contact with the container in the same plane from the horizontal direction of the container and for pushing the container by shortening the relative distance between the respective disk shape cutters, and further, the rotary table can be driven in the reversed direction if necessary. Therefore, even if once the cutting groove has traced the approximately helical locus, the disk shape cutters can reversely trace the approximately helical locus, and can newly draw the circular locus on the same periphery.
