Abstract

PURPOSE: To provide a cut-off end face of good appearance, by causing two kinds of upper cutters to play separate roles in cutting off a conbined material comprising an observe matel plate, a foamed core and a soft flexible reverse piece.
CONSTITUTION: A reverse material and a core material, which constitute a combined board 11 and can be broken or deformed relatively easily, are cut off by first upper cutters 23 placed in a front and a rear positions, to provide a neat undeformed cut-off end face. The observe material of the combined board, which is a hard metal or the like, is cut off by a second upper cutter 24. At that time, since the upper cutter 24 does not cut off the obverse material and the core material, said cut-off end face is not adversely affected. Since a lower cutter 23 is used, the cut-off end of the obverse material and its part near the end are protected from warp, deformation and scratches.
