ABSTRACT:

The operator snugs the edge of the tile up against a reference plate, and causes the elevator to press the tile towards the reference plate. The reference plate and the elevator are coupled with a transporter. The transporter is moved to maintain the tile in contact the guide surface, whereby the edge is placed into an edge shaping zone of a shaping tool, such as a router bit or a saw. Two or more shaping tools may be placed in series along the guide surface whereby the edge may be successively shaped by each shaping tool in a two or multi-stage process. A motor and a lead screw or a chain may be used to move the transporter and tile.
