Abstract
In the continuous production of polyurethane block foam, in particular from fast-reacting reaction mixtures which expand with rise time of less than 1.5 minutes, to achieve a good foam quality and a rectangular cross-section a centrally disposed mixer (44) is used, disposed downstream of which is a rubber-elastic plate (22), which is located in the feeding table (21) and in turn has a centrally disposed prop (33), associated with which, at right angles to the production direction and mounted laterally and symmetrically relative to said prop, are at least two adjustable props (32).
