Abstract

The kiln (1) comprises a motorized roller plane (2) on which glass sheets (4) rest while in the kiln (1). The roller plane (2) comprises motorized rollers (6) and is heated by means for heating (3); the roller plane further comprises tubes or pairs of tubes (5) which are arranged in the kiln (1) in proximity of the roller plane (2). An external surface of the tubes or pairs of tubes is on command and by directing of air into the tubes brought to a considerably lower temperature than an internal temperature of the kiln, so that a temperature of the rollers (6) can be regulated.
