Abstract

Method and apparatus for the continuous and automatic manufacture of both glazed and unglazed split tiles by accepting automatically produced uncured newly cut and/or stamped split tile and thereafter automatically glazing and/or hacking same for kiln firing. A first conveyor system is provided where previously cut unglazed split tiles are placed on a conveying system in a spaced-apart fashion, and moved to a transfer position. Thereafter, a whole row of the unglazed spaced-apart split tiles are transferred to a grouping table where layers for a hack are formed by a plurality of adjacent transferred rows. Each layer is subsequently transferred to a kiln car and oriented 90.degree. with respect to the just previously deposited layer so as to maintain the desired spaced relationship in the final hack. A second alternative conveying system is also provided in the preferred exemplary embodiment which moves unglazed split tiles individually through a glazing area where both sides are glazed. Thereafter, the glazed split tiles are dried and grouped in a spaced-apart fashion similar to the unglazed tiles. When a predetermined row length has been formed, such row is transferred to the same…
