Abstract

A bent glass sheet producing apparatus (20) has a heating furnace (21) in a heating zone (Z1), a preliminary forming mechanism (25) in a preliminary forming zone (Z2) downstream of the heating zone (Z1), a two-directional bending mechanism (30) and a conveyor roller mechanism (40) in a forming zone (Z3) downstream of the preliminary forming zone (Z2), and a cooling mechanism (50) in a cooling zone (Z4) downstream of the forming zone (Z3). For a purpose of conveying a two-directionally bent glass sheet formed by the two-directional bending mechanism, the conveyor roller mechanism (40) includes a plurality of conveyor rollers (41) having an arcuate shape of a radius (R2) in a direction perpendicular to the conveyance direction of the glass sheet, the conveyor rollers (41) being arranged on an arcuate line having a radius in the conveyance direction.
