<p>A new extrusion die for the production of hollow-chamber panels, contains two parallel slits (1), formed by lips (4, 5), for the extrusion of two parallel plane outside walls of a hollow-chamber panel and a core piece (2), which is placed between slits (1) and in which a multiplicity of cross-slits (3) are cut for the extrusion of webs and according to the invention one of the two lips (4, 5), which form slit (1), is designed flexibly and flexible lips (4, 5) can be adjusted by a multiplicity of control elements (7) which are independent of one another. By the new extrusion die, hollow-chamber panels with increased crosswise rigidity can be produced, since thickness variations of the outside walls, which would affect-the crosswise rigidity, can be reduced.</p> |
