Just in time for Blechexpo, the Schröder Group presents the brand new EVO DuoBend, a folding machine with two folding beams. This motorized folding machine ( working length 4000 mm, sheet thickness 4.0 mm) works with two independently operated folding beams. With the EVO DuoBend, the Schröder Group is once again increasing the flexibility of its up-and-down technology many times over: The new folding machine for up to 5 mm thick sheets has two independently operating folding beams. This opens up completely new possibilities for manufacturing large-format products with opposing bends. In special applications, the simplified handling results in enormous time savings and increased efficiency: Large trapezoidal sheets can be produced with two folding beams in one tenth of the time required with a single up-and-down folding beam.

Large-format sheet metal products with opposing bends, such as those used in container construction, for wind turbines or in special machine construction, are still often manufactured on press brakes with a high level of labor-intensive work. The folding beam of a folding machine with up-and-down function bends the product upward and downward with the swiveling folding beam. These machines have the advantage that sheets, once gauged, do not have to be turned, so that production can be handled by one machine operator alone. With the innovative EVO DuoBend, Schröder extends this principle: The folding of a negative bend is performed by the top folding beam and the folding of a positive bend is performed by the bottom folding beam. This eliminates the need to bypass product sides that have already been bent, which means that there are no longer any restrictions due to the maximum bypass radius of less than 200 mm. The prime example of such workpieces is a customized trapezoidal sheet.
