Abstract
An apparatus (10) for conveying a glass sheet (12) disclosed includes an air floatation glass sheet heating furnace (14) having a downwardly sloping heating bed (15). The furnace (14) includes an endless conveyor means (18) revolvable in situ and a plurality of restraining bars (20) supported by the conveyor means (18) and revolving with the conveyor means (18). The restraining bars (20) are movable sequentially adjacent the heating bed (15) and away from the heating bed (15) while revolving with the conveyor means (18). The restraining bars (20) are adapted to engage a leading edge of the glass sheet (12) to restrain the sheet so that the glass sheet (12) is moved along the heating bed (15) at a conveyor speed while the restraining bars (20) are moved adjacent the heating bed (15) and to slow the movement of the glass sheet (12) from the conveyor speed to a speed approaching a zero speed by a transition of the movement of the conveyor means (18) and restraining bars (20) from adjacent the heating bed (15) to away from the heating bed (15).
