ABSTRACT:
In forming heat-softened sheets by the roll forming method, continuously moving sheets of heat-softenable material, such as glass sheets, are conveyed continuously by spaced rotating cylindrical rolls along a conveyer into a roll forming station, where a set of rotating shaping rolls move transversely upward between adjacent stationary cylindrical conveyor rolls to provide rolling engagement against the lower surface of each moving glass sheet in succession in spaced relation above the level of the path of travel defined by the stationary conveyor rolls for sufficient time to shape the sheets. The sets of rotating shaping rolls move the shaped sheet onto a conveyor that extends through a cooling station. The sheets are flat entering the roll forming station and shaped to a curved configuration on leaving the roll forming station. The upper surfaces of the sheets are not touched during said shaping.
