LINEAR CAGE FORMING FOR ROUND TUBES

This new technology, developed and patented by Olimpia 80, opens a new era in the production of steel

tubes. This new concept of the Olimpia Group is the result of

many years of experience and of its excellent knowledge of the business field. It is a revolution in this

advanced production process.

It is a unique and compact system consisting of 11 sequential stations, 8 of which operating as breakdowns and 3 operating as finpasses.

This combination lets a final and almost complete closure of the tube be achieved

easily.

The 56 independent axles, operated by computerized servomotors and thanks to an easy use of the operating interface system, help to reach in a quick and simple way the

optimal position for the correct tube forming.

The strip feeding is assured by a system of independent pinch-rolls, which are installed

on the first 6 stands.

• GREATEST FLEXIBILITY IN ADJUSTMENT • EXTREME REDUCTION OF ROLLS’ SET

COSTS

The main ADVANTAGES of this innovative technology are:

• FAST AND AUTOMATIC CHANGE OF TUBE O.D. AND THICKNESS

•WIDE RANGES OF SIZES

• IT IS NOT NECESSARY TO CHANGE ANY ROLLS, ANY BREAKDOWN-STANDS AND EVEN ANY FINPASS.

• THE LINE IS COMPLETELY AUTOMATED
