DREISTERN  Front runner Rollformíng Machines

Usually, machines of this caliber are designed for relatively simple profile geometry and looser tolerances. However, this is completely different with this Dreistern system series. Complex profile geometry, extremely tight tolerances, and shortest changeover times, even for complete product changeovers, position this machine in a class by itself. The physical dimensions of this system are impressive as well, containing nearly 40 forming stands and a cut-off unit for a maximum of 52 feet (16 m) long cross-sections. This machine can work both continuously and in the Start-Stop operation, providing an unsurpassed flexibility when bringing highly precise punch patterns into the finished profile.

This task is handled by the remarkable cut-off system Jumbo. The 79 in x 89 in (2.0 x m) large table surface houses two separate presses. One serves for the separation of the profile and the other one for hole-punching. Alternatively, shears, presses, cut-off saws, or high-speed cut-off saws can be mounted on this table as well. Due to hydraulic clamping, the changeover takes only a few minutes. This means that you can now select the optimal cut-off process tailored to each application. Special electro-positioning devices provide a fast adjustment for each profile, and an accurate cut-off accuracy of in mm can be achieved. With each cut-off or punching cycle, the servo-drive of the machine accelerates an enormous 10 metric tons within a distance of only 7.9 in (200 mm) to the full rollforming speed.

The fascinating technology behind this Dreistern machine is opening new horizons. It especially serves the productivity and quality goals of demanding profile markets. The heavy precision profile market is experiencing above-average growth. Therefore, it is no surprise that Dreistern systems can be found at Europe’s successful rollforming companies.
