  • Patent number: 7201571
    Abstract: The invention relates to a method for extrusion, in particular for the production of bent extruded products, in which the extruded product (8) is formed in a die mounted before a support yoke (2) of an extrusion machine and then bent or curved by means of the effects of an external force, whereby at least one bending radius is formed, within the support yoke, on the extruded product (8) which enters the support yoke (2) with a straight extrusion direction (4). An extrusion unit further comprises a support yoke (2) formed with a lateral yoke opening (3), running transverse to the straight extrusion direction (4).
