METHOD AND APPARATUS FOR FAST FIRING GLAZED CERAMIC TILE TRIM

摘要

The method and apparatus for fast firing glazed ceramic tile trim pieces includes passing the trim pieces through a firing chamber by means of ceramic rollers which are designed to move the trim pieces in substantially a straight line through the chamber. The rollers include trim piece supporting surfaces which are inclined relative to a horizontal plane to cause gravitational forces to maintain the trim pieces against aligned orienting stops. Deposited glaze is removed from the rollers by periodically increasing the firing chamber temperature to a point where the glaze will release from the supporting roller and redeposit on a porous refractory passed over the roller.
