Abstract
An apparatus for shaping deformable materials during molding processes. Such an apparatus includes, among other things, a vibrating wall assembly. The vibrating wall assembly fits the contours of at least a portion of a mold's cavity. The vibrating wall assembly includes a pliable wall positioned within the mold. The pliable wall is positioned such that its outside wall surface is adjacent to a portion of the mold's inside wall surface; and its inside wall surface defines a portion of the geometric configuration of the material passing thereover. The pliable wall is designed to deform from its original shape when a positive or negative pressure is exerted on its inside or outside wall surface. This positive and/or negative pressure is generated, at least in part, by the displacement of a displaceable fluid. This fluid is contained within a chamber. The chamber is in communication with a portion of the pliable wall's outside wall surface. Also included is a device which displaces the fluid contained within the chamber. This device controls the amount, frequency and amplitude of the wall assembly's vibration by controlling fluid displacement.
