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 along a conveyor into a roll forming station, where a pair of sets of rotating shaping rolls move relatively toward one another to provide rolling engagement against the opposite surfaces of each moving glass sheet in succession in spaced relation to the conveyor for sufficient time to shape the sheets. The sets of rotating shaping rolls then move relatively away from one another to redeposit the shaped sheet onto the conveyor. The sheets are flat entering the roll forming station and shaped to a curved configuration on leaving the roll forming station. The present invention relates to a system of conveyor rolls capable of supporting heat-softened sheets that enter the roll forming apparatus in a flat condition and that leave the roll forming apparatus in shaped condition after they have been shaped by roll forming. The conveyor roll system also comprises a plurality of conveyor rolls toward the exit end of the roll forming station having a unique flexible structure that provides positive support for the shaped sheets leaving the roll forming station.
