Abstract: The present invention relates to an apparatus for the production of a solid-forming or a foam-forming reaction mixture from at least two flowable components, the apparatus comprising a mixing head, at the outlet opening of which is connected at an angle a filling tube in which an ejection piston which is designed as a piston head and having a piston rod of a smaller diameter is positioned, the rear neutral position of the piston head being located upstream of the outlet opening of the mixing chamber, characterized in that an introduction slit is provided in the filling tube between the rear neutral position of the piston head of the ejection piston and the outlet opening of the mixing chamber and a delivery device for cleaning platelets is associated with the introduction slit.

Abstract: The invention relates to equipment for the continuous production of foam boards, which may be laminated between facings, from a liquid foamable reaction mixture. The apparatus broadly comprises a conveyor, a foam mixture application device located at or near one end of the conveyor and a transverse foam mixture distribution device located downstream of said application device and above said conveyor, the space between said distribution device and said conveyor being adjustable.
