Abstract
A system is provided for molding a slurry containing particles in a solution of solvent and binder, which enables the close control of the production of a tape with particles of a high density. A rotor forms a chamber with a cylindrical molding surface, and a conduit carries the slurry from the outside to the surface while the molding surface rotates to use centrifugal force to force particles against the molding surface. The chamber is substantially closed to avoid the uncontrolled loss of solvent, and a means is provided for venting the chamber to remove solvent therefrom after the slurry has been molded into a tape. A container lies within the chamber and holds solvent prior to casting the slurry, to create a solvent-containing environment within the chamber.
