that cannot be achieved with conventional techniques, and that at costs that can be compared favorably with the costs of known technologies.

Known methods use drawing tools through which the material is drawn or pressed. Apart from the inaccuracy due to the wear and tear of the drawing tool, there is always the problem of keeping the core of the drawing tool correctly aligned with the shell. Without a single alignment, the wall thickness cannot be controlled, and it is common practice that the wall thickness in commercial pipes can change by up to 2Qff>.

In order to avoid these difficulties and disadvantages, the invention makes use of the concept of subjecting the pipe to a rolling process, internal or external, which is exerted by a series of small rollers which are arranged so that they rotate and profile the pipe, if so dispenser in line contact, by progressively to the pressure of the tube a small area eohv exerted extensive übar, so that the intensity of the pressure is hoöh.

Each roller 16 has a convex profile. If the lobes are "square" in the form of a pipe, external means must be provided by which the pipe is pulled through the throat. Any device suitable for this purpose may be used, such as a chuck that grips the front end of the pipe, or a reel that does the drilling. Vorlugeweise the rollers are, however, arranged so that they serve to pass Susi around the tube by the pulling tool, or at least this Hindurehsieh @ n "nt ar support"? .U this purpose the rollers obliquely mur axis üev throat are arranged so that they have a Kind of screw thread form »nit ds« the drill is driven.

According to FIGS. 8 and 9, it is ensured that the tubular «V / Erk-8tuck 38 runs axially through a groove formed between belonging Rollers 40 is formed, which rotate about fixed axes. A rod 42 lies coaxially within the throat and inside the tube to a tube, including a tubular holder 44, which is slotted is to rotatably receive a series of rollers 46 which us their Rotate axes, which are held in a fixed position relative to the rollers 40, specifically by means of the holder 441 «ie in FIG. 8 shown.

In operation, the tube 38 is presented to and through the throat pulled or pushed. The rollers 40, or one or two of them, is or will be rotated, "oduroh the tube 36 turns. The rod 42 is simultaneously in the opposite direction turned. This causes the rollers 46 to rotate. When the pipe is between the rollers 46 and the rollers 40 advances, it is given a uniform inside diameter by the rollers 46, wherein the pipe is supported by rollers 40. In this way, the inside and the Auesendurohmesser are set at the same time. In both cases, the pipe preferably has an approximately

In the case of FIG. 14, almost the length of the pipe 80 is finished by a device according to the invention or in some other way. Danaoh the Bohr is attached to a dome 82, which sits loosely and has a shoulder 34 against which the end of the pipe rests, and which marks the boundary between the lingdee Bornes which enters the pipe and part of it. it has a · »diameter that is exactly the same as that to which the pipe diameter is to be brought. This larger diameter is used as a guide over which a cylindrical housing 86 runs which, with a counterbore 88, carries a series of small rollers 90 which revolve the pipe and define a circle which is exactly the same diameter The drill is to be brought · It is ensured that the housing is traversed over the tube and is set in rotation at the same time as a drive "for example" ine "gear wheel 92, which has teeth 94 on the Uafaag the Geh & uaes kiaat. The gear wheel 92 is set in rotation by a shaft 96 which is driven with a "Ri""en9", which runs a Hieeenscheibe 100 on the shaft. The rotation of the housing ensures that the rollers 90 revolve the pipe and profile the drill between itself and the housing to the prescribed outside diameter and on the same side there are axes
