Abstract A method of heating a glass sheet which is moved on a conveyor which contacts one face of the sheet. In order to reduce the contact between the contacted surface of each glass sheet and to keep the leading edge of each sheet clear of the conveyor, anticlastic bending of the sheet is caused, and the stable anticlastic shape of the sheet is determined such that the sheet is arched away from the conveyor transversely of the sheet with respect to the conveying direction and with the sheet having a reverse curvature along its longitudinal extent so that the leading and trailing edges of the sheet are bent away from the conveyor. Anticlastic bending of the sheet is caused by producing a temperature differen- tial between the central area and at least a part of the periphery of the sheet, for example, by heating said part of the periphery.
