This automatic device is intended for being placed in line with a reducing rolling mill. KOI feed a new unreduced tubular elements into the rolling mill as soon as the rolling mill has reduced the previous element.
The hopper places the heating element in contact with the high tension tester (dielectric strength test). If the element fails the test, it will be sorted out. The approved elements will be fed into the rolling mill by means of motorized rolls. The feeding interval is adjusted to the element length.
A sensor detects when there are no more elements to be fed and stops the line.
