发明名称 Compound bend roll forming
摘要 A roll forming apparatus for shaping heat-softened glass sheets into a configuration having a longitudinal radius of curvature that varies in a direction transverse to the glass sheet. Opposing ends of each forming roll are mounted along continuous arcuate paths defining two different longitudinal radii. Quenching rolls are mounted downstream of the forming rolls with each opposing end mounted along a continuation of the corresponding longitudinal radii.
