ABSTRACT:
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 furnance (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'), 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.
