The present invention relates to a process and a device for applying tensile forces, with no contact with solid walls, to glass sheets, in particular at high temperatures, wherein a gas or vapor is blown between the glass sheet and a wall closely approached, and parallel, to said glass sheet. Between the glass sheet and said wall a gas cushion is established, in that the sections through which the gas flows inside the air gap between the glass sheet and the wall increase on the average in the direction of streaming of the gas, so as to allow the gas speed to decrease, and a recovery in gas pressure to consequently take place. Several forms of practical embodiment of the device are disclosed.

Abstract

The present invention relates to a process and a device for applying tensile forces, with no contact with solid walls, to glass sheets, in particular at high temperatures, wherein a gas or vapor is blown between the glass sheet and a wall closely approached, and parallel, to said glass sheet. Between the glass sheet and said wall a gas cushion is established, in that the sections through which the gas flows inside the air gap between the glass sheet and the wall increase on the average in the direction of streaming of the gas, so as to allow the gas speed to decrease, and a recovery in gas pressure to consequently take place. Several forms of practical embodiment of the device are disclosed.
