Abstract
Method and apparatus for cutting extruded split tile columns in a quick, efficient manner that reduces the possibility of damage and effectively doubles cutting speed. The apparatus cuts the moving split tile column as it moves away from the extruder and includes oppositely mounted, freely movable cutting discs which roll through and cut that split tile column when moved vertically therethrough. Cutting occurs on both up and down strokes with the cutting apparatus being moved relative to the moving column to a predetermined amount to a new cutting position after each stroke. The discs can be mounted in the same plane, arranged 90.degree. to the column's moving direction positioned so as to just touch each other or the discs can be in two separate and slightly offset planes so that the discs can overlap. Alternatively the discs could be spaced apart a predetermined distance and a secondary cutter used in a following manner to finish cutting a very narrow portion in the center of the column comprised of the rib and rear tile surface.
