摘要

A straight-through furnace for the heating of glass sheets to their bending and/or toughening temperature is provided with a conveying system bringing the glass sheets (2) in a horizontal position through the furnace (1). The conveying system includes a series of support plates (6). The support plates (6) are each formed of a rigid frame, which is equipped in the manner of a drum skin with a heat-resistant membrane (8) as the support surface for the glass sheet (2).
