Abstract
A device for supporting a ribbon of glass, having at least one roller arranged in an area of an underside of the ribbon of glass. In order to keep a ribbon of glass as free as possible of mechanical damage during production, at least one support device is assigned to the roller. With an actuating device the roller or the support device can selectively be contacted with the underside of the ribbon of glass, wherein the support device is in contact, at least in some areas, with the underside of the ribbon of glass by way of a gas cushion. The rollers are then employed at the start of production or after a ribbon of glass has snapped off in order to transmit an advancement force to the ribbon of glass.
