ABSTRACT:
An apparatus for applying a modifying ingredient to a mass of open-celled polyurethane foam includes the application of an excess of a liquid solution or dispersion of the modifying ingredient to the mass of foam. A fixed frame mounts a plurality of spaced, generally parallel lower backing rollers. A movable frame is mounted above the fixed frame and carries a plurality of spaced, generally parallel pressure rollers for movement toward and away from the backing rollers. A first adjustment device is provided for lowering the movable frame to move the pressure rollers toward the backing rollers, with the mass sandwiched therebetween. A plurality of second adjustment devices are spaced at locations about the rollers for adjusting the pressure between the backing rollers and the pressure rollers uniformly along the rollers both in a direction transversely to and in the direction of movement of the mass through the rollers.
