摘要： A method and apparatus for the continuous production of skinless or low skin flexible polyurethane foam (2). To reduce the thickness of the solidified skin on the surface of the polyurethane foam (2), the foaming occurs in a closed space (11). The environmental conditions during foaming are controlled by maintaining a gas-saturated atmosphere inside the closed space (11) using a gas or a mixture of gases different from ambient air. The closed space (11) is closed by a cover (12) which extend between the side-walls (9), from the mixture feeding point (16) and over a conveying path (4, 5). The reduction of the skin allows a greater percentage of polyurethane mixture to be usefully transformed into an expanded foam (2).
