Progressively angled and adjustable conveyor roll device for preliminarily bending sheet glass |
摘要 |
A glass sheet that has been heated nearly to a softening point thereof is preliminarily bent by a conveyor roll device while being fed along a feed path to a bending press. The conveyor roll device has a succession of first straight rolls spaced along the feed path for supporting a central region of the glass sheet, and a succession of second straight rolls spaced along the feed path for supporting a marginal edge portion of the glass sheet. The second straight rolls are vertically tilted through progressively differing angles, respectively, along the feed path with respect to the first straight rolls. The first and second straight rolls alternate with each other along the feed path.
