Abstract
A method and apparatus for embossing foil to produce warp-free, textured packaging sheet. The method comprises the forming of bosses in the foil while firmly supporting the foil clamped on rigid lands at the perimeter of the boss to be formed. Drawing the foil between rigid male and female walls of a forming cavity while so held, and interposing a sheet of yieldable material between the surface of the female portion of the cavity and the sheet of foil to produce a yieldable matrix against which the foil comes to rest.
