Abstract
1. Drawing device for tubes having a dished tube walling at their end, characterized in that - a spike-shaped drawing rod (15) rests with its head (16) against the interior of the dished tube walling (12), whereas a shaft (17) of the drawing rod is protruding ; - the drawing rod (15) is guided by means of an axial pole (22) mounted at its rear end in a bore of the drawing stopper (20) and in the stopper rod (23) formed as a tube ; - for the back transport of the drawing rod (15) after the drawing process, there are provided in the region of the drawing nozzle (14) driving rollers (24) which by means of transverse transport can be brought into an abutment in a free section of the axial pole (22) ; characterized by the following further features : - behind the drawing stopper (20) there are provided slots (27) in the tube (23) serving as stopper rod for the passage of the driving rollers (24).
