Abstract
A bending installation includes a shaping bed, an evacuation conveyor positioned downstream of the shaping bed and a swinging device for swinging a glass plate exiting the downstream end of the shaping bed from the shaping bed to the evacuation conveyor. The shaping bed is curved in a direction of advance of the glass plate and has a conveying direction different from that of the evacuation conveyor. The swinging device takes the form of a rotating drum mounted coaxially with a support roller. The drum includes holding rollers spaced from the support roller by a distance sufficient that a glass plate exiting the shaping bed is held between a holding roller and the support roller, so that the swinging device is swung by the weight of the glass plate to a position where the glass plate is transferred to the evacuation conveyor. A tempering air blowing box may be provided on the swinging device.
