  • Foam board having improved evenness and the method and apparatus for its continuous manufacture
    Patent number: 4347281
    Abstract: A plastic foam-forming mixture (20) is dispensed between upper and lower paper sheets (11 and 17) and the whole conveyed through metering rollers (14 and 15) to spread the mixture. The mixture is allowed to expand under a constant pressure supplied by a floating drag platen (21). Suction is applied to the upper sheet through apertures in the platen. Suitably the platen consists of a series of rigid slats (22) hinged lengthwise transversely to the direction of the sheets, imparting longitudinal flexibility to the platen in that direction. Suction may be applied through apertures in the ends of every third or fourth slat. Improves the evenness of foam board.
