(57) A slasher (1) has a sizing tank (4) provided with a movable weir (18). The level of the movable weir (18) is lowered temporarily below a predetermined level of a sizing solution (3) contained in the sizing tank (4) while the slasher (1) is in a steady-state operation to let scum including bubbles (25a) and floating matters (25b) floating on the surface of the sizing solution (3) overflow the movable weir (18) so that the scum is removed from the sizing tank (4) while the slasher (1) is in the steady-state operation.
