ABSTRACT:
An apparatus for producing seat or backrest cushions from plastic foam in which the hardness of the cushion varies in different regions of the cushion. The components for making the different plastic foam mixture are first mixed in a mixing head, and then, depending on the desired hardness of the respective parts of the cushion, the respective mixture is then passed from the mixing head into a mold corresponding to the configuration of the cushion to be produced. The apparatus comprises a mixing head which is stationary in relation to the mold during operation of the process, and communicates with a distributor which opens into the mold and which deflects the respective foam mixture issuing from the mixing head into the designated regions of the mold.
