Abstract (en)
[origin: EP2532449A2] The rolling device (1) has a feed motion channel (4), a pipe loop supply (8) and a pipe loop feed motion (5) that shifts the pipe loops from the feed motion channel through a planetary cross rolling mill (3). The pipe loop feed motion has a feed motion device (7). The device has a mandrel (11) and a mandrel bar holder (12). The pipe loop supply has an axial pipe loop feeder (9) which conveys the pipe loop axially in a supply position (10) which is provided axially behind the mandrel bar holder.The feed motion device has a plunger (13). An independent claim is included for a method for rolling tube loops with a planetary cross rolling mill.
