  • Method for casting using a casting head having a variably displaceable cavity surface
    Patent number: 6780354
    Abstract: A method employing a casting head having a variably displaceable cavity surface. The casting head comprises a cavity, at least partially formed by plurality of surfaces, including a carrier surface adjacent the cavity, and a variably displaceable drive surface for controlling a pressure of a viscous casting material in a region proximate the carrier surface. In one embodiment of the invention, the casting head further comprises a doctor blade, disposed proximate the carrier surface, forming a gap therebetween for egress of the casting material. In another embodiment of the casting head, the variably displaceable drive surface is comprised of a piston. The piston is actuated by a driver-controlled motor according to a pre-determined displacement program, or according to the level of the casting material in the cavity.

  • Constant pressure casting head using variably displaceable cavity surface
    Publication number: 20030201558
    Abstract: A casting head having a variably displaceable cavity surface, and a method for using the casting head to produce films is disclosed. The casting head comprises a cavity, at least partially formed by plurality of surfaces, including a carrier surface adjacent the cavity, and a variably displaceable drive surface for controlling a pressure of a viscous casting material in a region proximate the carrier surface. In one embodiment of the invention, the casting head further comprises a doctor blade, disposed proximate the carrier surface, forming a gap therebetween for egress of the casting material. In another embodiment of the casting head, the variably displaceable drive surface is comprised of a piston. The piston is actuated by a driver-controlled motor according to a pre-determined displacement program, or according to the level of the casting material in the cavity.
