Machine for the continuous production of lined foam panels

摘要: Abstract of EP0437727The machine for the continuous production polyurethane foam panels lined with outer layers has two endless conveyor belts, defining a mould cavity between them, and lining gantry, on which there are arranged mixing heads (11, 12), can be moved independently each other into position above lower belt or layer. To head leads component supply line (14, 15) from metering station 13. Provided lines is permanently open connecting (16). In foaming position, preferably oscillate transversely to direction production. According invention, it possible always have one in operation when being cleaned maintained. It not necessary interrupt this purpose. The connected such way that, changing over, no errors occur due pressure fluctuations. If switched off, continues flow through corresponding switched-off head, but instead flowing flows head. Consequently, permanent throughflow irrespective whether not. depends (Fig. 2).
