Abstract

An apparatus for producing two-dimensionally bent and optionally tempered glass plates includes a roller oven (1), a pressing and bending station (2) and a cooling station (3). A lower male mold-like, full surface bending mold (10) with two-dimensionally shaped bending surface is arranged in the pressing and bending station (2). The top surface of the bending surface of the bending mold (10) is located in the conveying plane defined by the conveying rollers (5). The wall of the bending mold (10) forming the bending surface is provided with bores (14), which can be supplied with hot gas for forming a hot gas cushion. After positioning the glass plate (4) on the hot gas cushion, the female mold-like frame bending mold (11) is lowered onto the glass plate (4). The bent glass plate slides on the hot gas cushion into the cooling station (3).
