ABSTRACT:
An apparatus and method for demounting parts from the adhesive upper surface of a film has a base with a tool mounted thereon. A portion of the tool has a fluted surface extending above the base upper surface. The film lower surface is positioned above the base with a part on the film overlying and opposite the fluted surface of the tool. A vacuum is supplied through at least one passage in the base to the film lower surface to draw the film around and over the tool flute and force the part to at least partially separate from the film adhesive upper surface. The part that has been separated from the adhesive upper surface of the film is stripped from the film adhesive upper surface such as by applying a vacuum force directly to the part through a collet and moving the collet and base relative to one another.
