ABSTRACT:
Molded fibrous workpieces of various cross sectional configurations are coated with a polymeric latex foam coating material to encapsulate fibers and dust within the exterior surfaces of the workpieces. The foam coating is applied by passing the workpieces through a coating chamber filled with the polymeric foam so that the workpieces are totally immersed in the foam coating as the workpieces pass through the chamber. Openings for introducing the workpieces into and discharging the workpieces from the chamber have a configuration complementary to the transverse configuration of the workpieces. The foam coating is introduced into the chamber both above and below the path of the workpieces through the coating chamber to assure that the coating chamber remains fully charged with the foam coating. Brushes or wiper blades spread the foam coating over the exterior surfaces of the workpieces.
