Abstract (en)

[origin: EP0712673A1] To calibrate iso-pod rollers, for rolling thin-walled tubes from perforated hollow bodies, on a diverging roller, the transport angle of each iso-pod roller (1) is set at 7-17 degrees , according to the dia. and smoothed roller section length, where the transport angle is smaller with an increasing tube diameter. The spread angle (alpha) is set at 7-30 degrees . The opening angle (beta) of the round cone (5) is 4-15 degrees , formed between the extended mantle line of the smooth section (4) and the opposing mantle line of the short round cone.
