摘要： A clad tube (21) is formed by melting and extruding a polymer, such as PMMA. The molten polymer is extruded through an extrusion die (12) to form a soft clad (20). The soft clad (20) is forwarded to a molding die (13) to correct the shape of the soft clad (20). A decompression chamber (31) in the molding die (13) is decompressed so that the outer surface of the soft clad (20) is tightly in contact with forming surface (30b) of the molding die (13). After molding the soft clad (20) in the molding die (13), the clad tube (20) with low fluctuation in thickness is obtained.

摘要： In a method for producing a coiled tubing (RW) from a thermoplastic material, in a first shaping step a tubular extrudate (EX) is extruded via an annular nozzle gap (16) in an extruder (12) before, in a second shaping step directly following the first shaping step, the extrudate which is drawn down from the nozzle gap and is still plastically deformable is calibrated in a shaping device (18) in order to obtain a geometrically defined profile cross section (PQ) and is shaped into the coiled tubing, whereupon the coiled tubing having the geometrically determined profile cross section solidifies. This method allows for continuous production of the coiled tubing with a new, high quality in respect of dimensional and shape tolerances on the profile cross section of the coiled tubing. The invention also relates to a device (10) for producing such a coiled tubing.
