Zusammenfassung:	The method for drawing of profile thin-walled tubes includes the preliminary forming of the catch at front end of the round tubular billet with subsequent shaping and deformation of billet in the contour gage. Forming of the catch only at front end of that billet, which, during drawing, is first to pass through the drawplate, is performed by driving in of head. On the following tubular billets the catch forming is performed by reduction along the diameter of front end of the billet on the length, which is equal to the length of the catch of the first billet. During drawing front end of each billet with catch in the form reduced section prior to its approach to the contour gage is set in the opening of the rear end of previous billet, which has already been located in the gage.
