A method for bending glass sheets in an apparatus and an apparatus for bending glass sheets, the apparatus comprising at least one compartment heating the glass sheet to be bent, a press bending station which comprises a male mould to bend a glass sheet, brought through at least one compartment heating the glass sheet to the press bending station by pressing it, and at least one conveyor to transport a mould trolley that may be provided with a female mould and a glass sheet placed on the female mould through the at least one compartment heating the glass sheet to the press bending station. In order to replace the male mould in use at the press bending station with a male mould to be used next, a trolley is delivered which is suitable for carrying the male mould to the press bending station to receive the male mould to be removed from use on said trolley to carry the male mould to be removed from use away from the press bending station by said trolley, and a trolley is delivered which is suitable for carrying a male mould and provided with the male mould to be brought into use to the press bending station in order to carry the male mould to be brought into use to the press bending station.

Method for bending glass sheets in an apparatus, and apparatus for bending glass sheets

A glass tempering furnace and a method for heating a glass sheet. The glass sheet is heated in the glass tempering furnace by blowing heating air on the top surface of the glass sheet, and the blowing distance of the heating air from the top surface of the glass sheet is adjusted.

Method for heating glass sheet, and glass tempering furnace

The invention relates to a method for heating glass sheets, and a glass tempering furnace. The glass sheets are heated by feeding them through a tempering furnace whereby the glass sheets are heated from above and below in the tempering furnace. The glass sheets are heated with blowing channels arranged substantially transverse in relation to the direction of travel of the glass sheets and with heating resistor rows arranged substantially transverse in relation to the direction of travel of the glass sheets. A heating resistor row has at least three separately controllable parts, and the temperature profile of the glass sheet is adjusted in the transverse direction by separately adjusting the different parts of the resistor row.
