ABSTRACT:
The present invention provides a ring mold for shaping heat-softenable sheet material. The mold includes peripheral wall members enclosing a central cavity having an open upper end. The wall members have an upper sheet shaping surface with a peripheral shape and elevational contour that generally corresponds to a desired peripheral shape and elevational contour of a sheet to be shaped. A first set of slots are positioned along and extend through portions of one of the wall members and a second set of slots are positioned along and extend through portions of an opposing wall member. Each of the slots in the second set is generally horizontally aligned with a corresponding slot in the first set.
