ABSTRACT:
A method and apparatus for producing an elongated beam from compressible material. A mixture of filling material and plastic material is delivered to a first space and there compressed. The compressed material is pressed through a nozzle into a second space defined by a matrix of wall parts, where the material is made more rigid. The wall parts of the matrix can be moved backwards and forwards in a particular sequence to enable beam parts to be fed continuously through the matrix.
