Abstract
A holding device for glazing panes heated in a horizontal position to a deformation temperature comprises a downwardly facing contact surface, to which the glazing pane is held by suction action. The contact surface is formed of a tensioned fabric of highly heat-resistant fibers. As the glazing panes are sucked on, the fabric yields and bulges upwards. The amount of the bulge of the fabric is dependent upon the tension in the fabric. By the bulging of the fabric the glazing pane undergoes a bending opposite to the succeeding bending of the glazing pane under the effect of its self-weight. This counter-bending compensates an undesired transverse bending during the later bending process.
