Abstract
The invention is directed to an apparatus for the production of polyurethane moldings endless in one dimension using at least two alternately operated mixheads for the reactive polyurethane components. Material which has been correctly conditioned by circulation of the reactive components through the mixhead not in operation arrives at that mixhead at least before it is put into operation and the components are delivered by units which are common to the mixheads, but independent of one another in regard to 'mixing' and 'conditioning'.
