METHOD AND TUBE FOR MANUFACTURING MULTI-LAYER TUBE HEADS AND TUBES FROM MORE THAN ONE PLASTIC LAYER CONTAINING TUBE AND MULTILAYER TUBE HEADS (Verfahren zur Hestellung einer Tube mit einem mehrschichtigen Tubenkopf und Tube aus einem mindestens eins Kun-ststoffschicht aufweisenden Rohrkorper und einem mehrschichtigen Tubenkopf)

摘要

The present invention relates to a method for manufacturing a tube from a pre-fabricated tube by pressing a heated plastic blank to form a multi-layered tube head that simultaneously joins the tube head to the tube body, The plastic blank is supplied to form the subsequent layer until the layer of the formed tube head is shaped and stabilized, and the plastic blank is compressed so that it is newly supplied when it is compressed or not, so that each layer of the multi-layered tube head is formed . The tube has a tube body (1) having at least one plastic layer and also a multi-layered tube head (2), which is formed by compression casting a heated plastic blank, (3, 6, 5) of the multi-layered tube head (2) are made of a tube body (11) having a recess (8) centered at a distribution opening (9) And compressed sequentially in layers, so that they are integrally formed at the one end of the tube 1.
