In a bending of heat-softened glass sheets by pressurized contact between a pair of shaping members having substantially complementary shaping surfaces and a fibre glass fabric is interposed between each shaping surface and each major surface of the glass sheet, the yarns of the fibre glass fabric and knitted together and/or are textured. Best results are obtained with texturized knitted fabrics. For concave, convex shaping surfaces, at least one more layer of fibre glass cloth is interposed between the glass surface and the convex surface than between the glass surface and the concave surface. U.S.A. Specifications 2,560,599 and 2,783,609 are referred to. |
