Abstract
An apparatus and method are disclosed for forming a fibrous workpiece comprised of a layer of randomly disposed fibers and adhesive material dispersed throughout the fibers for binding same upon heating and compressing the fibers and adhesive material to define a unitary pad wherein the apparatus comprises a press having a first and a second platen supported for relative movement toward and away from each other, a first and a second mold supported by the first and second platens respectively with the molds having forming surfaces which define the configuration of the pad, and means for heating the workpiece wherein the heating means comprises means for providing hot humid air through the workpiece to provide a rapid penetration and improved heating of the fibers and adhesive material resulting in comparatively high speed forming of the pad with a minimum forming pressure.
