发明名称 MULTI-LAYER PIPE AND METHOD FOR ITS PRODUCTION
摘要 The invention relates to a method for producing a multi-layer pipe (5) wit h the aid of a bending roller. According to said method, individual material layers (1,2), which are to be combined to form the multi-layer pipe (5), are laid on top of one another and the multi-layer material that is thus produced is shaped to form a multi-layer pipe (5) with the aid of the bending roller. During the final phase of the pipe shaping process by the bending roller and/or a bending machine that is subsequently used, a material layer (2) that acts as an external pipe (1) is pressed in a force f it into a material layer (2) that acts as an external pipe.
