| 摘要 |
The present invention relates to a method of reducing the severity of edge kinking that sometimes occurs when heated glass sheets are shaped by roll forming. The improvement comprises superficially cooling one or both side edge portions of each glass sheet between a furnace exit and a roll forming station where its undersurface is lifted by a set of lower rotating forming rolls having a concave configuration in their axial direction which is transverse to the direction of glass sheet movement.
