as it cannot be ironed on this. According to FIG. 2, the bar feeder 35 is an open one The invention is based on the task of the roller table. The centering for the mandrel bar ensures throughput of the tube rolling mill, and stands from the three-roller centering 17 in the by increasing the hollow body success. pivot levers 39, 41, 43 coupled to one another. According to the invention, this object is achieved because the pivot levers 29 and 33 are equally suitable

The working process with the tube rolling mill is as follows: A rolled out tube billet is held by the longitudinal conveyor 19 on the mandrel bar II ge jo. It is taken from the longitudinal conveyor Schrügwalzgcriist 1 moved out to the left in FIG. At the same time the mandrel abutment 13 with the The mandrel bar II located thereon is moved to position 14 in dashed lines. The mandrel bar Ii with the mandrel (plug) 9 that has not been thrown off, also leave the inclined roll stand I. The coupling 15 will open. Tube blank and mandrel rod 11 are of the pivot lever 29 ai. Ion longitudinal conveyor 21 handed over. The rod end with the mandrel 9 is held in the device 23, the conveyor belt 21 strokes the billet from the mandrel and guides it over the roller table 25 for further processing 49 to. After opening the device 23, the mandrel bar is also turned to the left in FIG. I. discharged: however delivered via the water basin 51 yn the rod bearing 37.

As soon as the rolling line has been cleared of a tube billet with a mandrel bar. will be in the rolling mill a mandrel provided with a mandrel and held ready in the bar supply 35 is transferred to the rolling line and the clutch 15 is closed. The mandrel abutment 13 is moved back into the working position. In the meantime, a new block for rolling has been inserted in front of the inclined rolling stand and the new rolling process can begin immediately.
