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.
Claims22
In 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, the improvement comprising:
- at least one support device assigned to the at least one roller, wherein the at least one support device contacts the underside of the ribbon of glass by way of a gas cushion;
- and
- an actuating device in combination with the at least one roller and the at least one support device, wherein the actuating device selectively and alternatively contacts the at least one roller or the at least one support device with the ribbon of glass.
In a device for supporting a ribbon of glass between a glass production or processing unit including a float tank and a cooling furnace, the device including more than one roller disposed in an area of an underside of the ribbon of glass, the improvement comprising:
- a plurality of support devices, a first of the plurality of support devices disposed between a first of the more than one roller and the glass production or processing unit, and a second of the plurality of support devices disposed between the first of the more than one roller and a second of the more than one roller;
- and
- an actuating device in combination with the more than one roller and the plurality of support devices, wherein the more than one roller or the plurality of support devices are selectively brought into contact with the underside of the ribbon of glass by the actuating device, and the plurality of support devices contact the underside of the ribbon of glass by way of a gas cushion.
