ABSTRACT:
Using a pair of driven knifing rolls having annular wedges therearound, one above the other, a relatively hot metal piece having a rectangular cross-section is cut into three or more narrower widths. The annular wedges hold and bite into the metal piece being transferred in the longitudinal direction thereof, thus forming V-shaped grooves in the metal. The angle formed between that flank which is closer to the as-cast side of the metal piece to be cut, upon which no cutting force is exerted, and a perpendicular to the roll axis is greater than the angle formed between the opposite flank and the same perpendicular, so that the cross-sectional shape of the annular wedge is asymmetrical with respect to a line segment that passes through the pointed end of the wedge and extends perpendicular to the axis of the rolls.
