ABSTRACT:
A tile perforating unit wherein tile is continuously advanced through a frame by advancing means. Moveably mounted on the frame and directed toward the tile is at least one perforating tool. From an initial position, the tool extends and engages a point along the wall of the tile at which perforation is desired. As the tool moves to maintain engagement with the advancing tile a harpoon is extended from the tool to perforate the tile wall. Once perforation is completed, the harpon is withdrawn and the tool retracts and returns to the initial position for repeated perforation of the tile.
