Abstract
A method for the production of a unitary or laminated film or sheet of finely controlled thickness from a molten material utilizes spaced, first and second parallel rolls rotating in opposite directions to form a kissing zone between the rolls. The method moves the surface of a cooling rotating roll past a region of contact with a molten material to form a rapidly solidifying layer of material thereon, which then is passed into the kissing zone, wherein the solidified layer is either pressed to form a unitary film or is fused by contacting another solidified layer.
