发明名称 APPARATUS AND METHOD FOR BENDING GLASS SHEETS
摘要 The present invention provides an apparatus and method for a shaping sheet including a support frame and a shaping rail supported on the frame. The shaping rail has a sheet shaping surface that conforms in elevation and outline to a final desired shape of a marginal edge of a glass sheet to be shaped. An auxiliary rail having a sheet shaping surface which generally corresponds to a preliminary shape of a selected marginal edge portion of the sheet is positioned along a section of the shaping rail having a sheet shaping surface portion which generally corresponds to the final desired shape of the selected marginal edge portion of the sheet. The auxiliary rail is mounted for movement relative to the shaping rail section from a first position, wherein portions of the sheet shaping surface of the auxiliary rail are above the sheet shaping surface portion of the shaping rail section, and a second position wherein the sheet shaping surface of the auxiliary rail is positioned below the sheet shaping surface portion of the shaping rail section. When the auxiliary rail is in its first position, it is capable of supporting the selected marginal edge portion of the sheet above the shaping rail section and preliminarily shaping the sheet. When the auxiliary rail is in its second position, the sheet shaping surface portion of the shaping rail section is capable of supporting and shaping the selected marginal edge portion of the sheet to the final desired shape.
