Abstract
In bending glass sheets to a complicated shape by a combination of gravity sagging the glass to a longitudinal component of bend while supported on an upward facing shaping surface of an outline mold and then lifting the glass so shaped off the outline mold onto a solid shaping mold of continuous extent to impress a complicated transverse component of bend, glass edge engaging members are provided closely adjacent to said outline mold to the outside thereof, means is provided to support said glass edge engaging members so that the upper edges thereof are located in position to abut the edge of one or more glass sheets as the latter sag toward said outline mold and to remove said glass edge engaging members suddenly and automatically from the vicinty of the edge of the supported glass sheets just before the glass sheets are lifted from said outline mold to said solid shaping mold to reduce edge distortion of the mold supported glass sheets.
