PURPOSE: To allow the unmanned long-time operation of the machine by constituting a chuter table as plural divided tables and constituting these tables in such a manner that the moving quantities of the respective tables vary.

CONSTITUTION: The work on a processing table is gripped by a gripper and is moved, by which the work is cut to a prescribed shape. The processing table is partly opened and closed and the cut products or scrap are sorted by the chuter tables. The chuter tables are constituted of the tables 7, 8 so as to be bisected (divided into plurality) at a groove part 6a. The tables 7, 8 are so constituted that the moving quantities thereof vary. The tables 7, 8 are moved by cylinders 9, 10. The need for the removal of the work and the operation for monitoring the machine by an operator is eliminated.
