Abstract
The present invention is directed to a device for inserting and thrusting a bar into a double rolling pressure piercing mill (PPM) machine comprises a drum-shaped bedplate coaxially keyed to a motor-driven shaft having its axis of rotation parallel to the PPM's rolling axis, a first and a second thrust means on the drum-shaped bedplate having acting lines (R R.sub.1) parallel to the PPM's rolling axis and circumferentially spaced from each other by a predetermined center angle, a motor for angularly moving the drum-shaped bedplate from a position in which the line R coincides with the rolling axis to a second position in which the line R.sub.1 coincides with said rolling axis and vice-versa.
