Zusammenfassung:The invention relates to a method and apparatus for manufacturing a bent glass sheet. A glass sheet (9) carried by rollers (7) included in a furnace (1) is transferred onto rollers (8) of a bending mould (10) included in a mould station (3) built as a part of the furnace. By adjusting the position of rollers (8) of bending mould (10) in vertical direction a glass sheet is bent to a desired curvature while heating it in furnace mould station (3). The roller mould (10), along with its bent glass sheet (9 min ), is carried out of furnace (1) and into a chilling station. When using a transferable and adjustable roller mould (10), the apparatus does not set limitations for the size or degree of bending of glass sheets to be bent.
