Abstract:
An apparatus for shaping a glass sheet, comprising:a support frame;a shaping rail supported on said frame the shaping rail having (1) a pair of spaced elongated members defined as a center section, each of the spaced members of the center section having a longitudinal axis extends in a first direction and being secured in a fixed position on said frame and (2) having a pair of movable shaping rail sections defined as a first movable shaping rail section and a second movable shaping rail section the first movable shaping rail section mounted adjacent one end of the center section and the second movable shaping rail mounted adjacent the other end of the center section the first and second rail sections are pivotally mounted for movement toward said support frame to a first position and away from said support frame to a second position wherein when the movable shaping rail sections are in the second position 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; andat least one elongated auxiliary rail having a longitudinal axis, the at least one auxiliary rail having a sheet shaping surface, positioned adjacent one of the movable shaping rail sections of said shaping rail, wherein said movable shaping rail section has a sheet shaping surface portion generally corresponding to said final desired shape of a selected marginal edge portion of the sheet to be shaped, said auxiliary rail mounted for movement relative to said movable shaping rail section between a first position, and a second position such that the longitudinal axis of said auxiliary rail is transverse to the longitudinal axis of the elongated member of the center section, wherein when said auxiliary rail and said moveable shaping rail sections are each in their first position, portions of said sheet shaping surface of said auxiliary rail are above said sheet shaping surface portion of said movable shaping rail section and wherein when said auxiliary rail and said moveable shaping rail sections are each in their second position, said sheet shaping surface of said auxiliary rail is below said sheet shaping portion of said movable shaping rail section.
