Abstract
A rotatable roll is provided under a planing cylinder rotating at a fixed position. A front feed unit and a rear feed unit having an upper and a lower roll for gripping the plate are provided upstream and downstream of the planing cylinder with respect to the feed direction of the plate. A front movable body and a rear movable body having an upper and a lower roll for gripping the plate member are provided between the planing cylinder and the front feed unit and between the planing cylinder and the rear feed unit. The upper and lower rolls of the front and rear movable bodies are forcibly moved up and down. The plate member is supported at three points and deflected downward to prevent floating of the plate during cutting and to prevent the formation of depressions in the plate near its front and rear ends during cutting.
