摘要： A method for the continuous production of foam blocks or foam sandwich panels involving the application of the liquid foamable reaction mixture to the continuously moving shaping support in a manner which avoids large gas inclusions in the final product produced. The liquid foamable reaction mixture is preliminarily distributed by the use of a particular distributor channel means in a traverse direction to the continuously moving shaping support, permitted to flow in the form of a descending film exposed to the atmosphere to an intermediate storage means and then conveyed to said continuously moving shaping support. The distributor channel means may also be pivoted to control the outflow of the mixture.
