Abstract

The invention concerns a method and an apparatus for tube manufacture. The invention enables the cold-drawn production of curved tubes by means of a hollow tube (10) first undergoing a sub-process for the reduction of the external diameter and thickness of the tube wall. The invention is characterised by a straight tube being drawn through a drawing tool held by a drawing plate (13) and by a mandrel (12), which is short and straight relative to the tube and is positioned centrally within it. After exiting the drawing plate the tube takes up the requisite curved shape because the tube drawing device (15,16) holding the end of the tube draws it into a predetermined curved path, in surface contact with a guide (17) with the above mentioned requisite curved surface, mounted on the drawing plate.<IMAGE>
