APPARATUS AND METHOD FOR REFORMING SHEET MATERIAL

摘要

A mold has a sealing surface bearing a sealing profile. A plenum has a sealing surface bearing a sealing profile. The mold and plenum together form an apparatus for reforming a sheet material. In the closed position of the apparatus, the sealing profile of the mold is in opposing relation to the sealing profile of the plenum and the sealing profiles of the mold and plenum together define a profiled sealing gap. When the sheet material is wedged into the profiled sealing gap, a direct seal will be formed between the sheet material and each of the mold and plenum, resulting in two forming areas within the apparatus.
