Abstract

825,796. Bending glass sheets. PITTSBURGH PLATE GLASS CO. Aug. 20, 1957 [Aug. 27, 1956], No. 26244/57. Addition to 768,982. Class 56. The inboard edge 68 of the heat absorber 64 positioned beneath the outboard ends of the pivoted end sections 38 of a glass bending mould M that produce relatively flat ends of the concavely bent sheet is made substantially parallel to the transverse axis a ... a connecting the points of sharpest longitudinal curvature in the sheet instead of lying along the line 641 as in the parent Specification. The edge lies outboard of the axis and it may be curved so that its extremities are nearer the axis than is its central part.
