ABSTRACT:
This invention relates to securing a cover of flexible material such as fiber glass cloth tightly against a shaping surface of a solid mold used to shape glass sheets. The securing means is located within the outline of the solid mold to avoid having cover attachment means beyond the solid mold outline. This permits the use of a solid mold of maximum size compared to that of an outline mold when glass sheets are shaped by a process that requires the solid mold to pass through a position occupied by an outline mold.
