  • Patent number: 4031709
    Abstract: Disclosed is an apparatus to detect misaligned clay tiles in the chute of a tile-laying machine and realign any tiles incorrectly aligned. The apparatus is capable of being retrofitted onto existing tile-laying machinery as well as being incorporated into improved future designs. The apparatus is comprised of alignment sensing switches which in turn control solenoid operated repositioning levers. The levers realign the ceramic tiles such that they are properly positioned to avoid gaps in the tile field.
