<p>The invention relates to a method and to an arrangement for producing an elongated beam (A) from compressible material. A mixture of filling material and plastic material is delivered to a space (3) and there compressed. The compressed material is pressed through a nozzle (4) into a second space defined by a matrix, where the material is given a more rigid form. The wall parts (11, 12, 13, 14) of the matrix (10) can be moved backwards and forwards in a particular sequence, so as to enable beam parts (A) to be fed continuously through the matrix (10).</p> |
