Abstract
A roller for conveying sheets of glass, includes at its surface a conveying zone for the sheets of glass, the roller including a straight axis of revolution, the conveying zone forming a curved surface of revolution about the axis of revolution, the roller being asymmetric on either side of its, minimum or maximum, extreme diameter. A plurality of the rollers can also serve to bend running sheets of glass.
