Claims (2)

  1. A method of fabricating an article, which comprises deforming a flexible sheet to locate selected portions thereof at one side and other portions thereof at the other side of a predetermined line, moving a cutting tool along said line and in cutting engagement with said deformed sheet to remove only said other portions from said sheet, and retaining said cut flexible sheet in said deformed state by securing a backing to the areas of said selected portions of said sheet that were at said one side of said line during the movement of said cutting tool while said cut flexible sheet is in said deformed state.
  2. A method as defined in claim 1, in which said sheet is deformed by forcing said selected portions thereof into and retaining the same in depressions in a surface of a holding fixture, said line of movement of said cutting tool is in a plane parallel with said surface, and said backing layer is secured to cut and uncut areas of said sheet that are in said plane parallel with said surface of said fixture while said sheet is being retained in said depressions.
