ABSTRACT:
A lehr for heat treating glass articles is assembled from a series of modules to define an elongated insulated tunnel. A belt conveyor extends throughout the tunnel for moving articles from one end to the other. Duct work connection between the tunnel and the ambient air and associated heating and blower means establish heating, tempering and cooling zones respectively within the lehr in the direction of conveyor movement. Temperature sensors adjacent both flights of the conveyor are linked with a control panel to permit establishment of any desired temperature curves.
