Lübke Baumetal GmbH supplies a wide range of metal solutions for roofs and facades; everything from standard profiles to bespoke productions, nothing is too much for this company from Arnsberg in North Rhine-Westphalia. For Lübke, success rests on first-class products that come from a comprehensive consulting service combined with a fast distribution system.

The most complex step in the production of these precision pieces is the efficient bending of the profiles. That is why Lübke relies on not one, but three RAS folding machines: two GIGAbends and one XLTbend with up-down bending technology and a 45° upper beam. All of these machines are available in the UK from Press & Shear.

Lübke’s love affair with RAS began in 2007 when the company purchased the first GIGAbend bending machine with a working length of 3 m. Another machine of the same model arrived in 2012. At the beginning of 2021, a RAS XLTbend with a bending length of 4 m and a sheet steel capacity of 2.5 mm was added to the already robust folding line-up.

Production manager Jan Rengshausen says: “We can absolutely rely on these machines, both in terms of reliability and bending quality.”

The employee responsible for the up-down folding machine is Christian Hellweg. Using the Bendex software, he creates the bending processes for the drawn or imported profiles. The software automatically calculates different bending sequences and suggests the best variant to the machine operator. Whenever possible, Hellweg tries to apply the profiles from the stop-side.

Says Rengshausen: “We made a comparison with kick protection profiles and needed about 10 minutes for the classic bending of 10 parts. The same parts on the XLTbend were finished after 6.5 minutes: a decisive speed advantage of 35%.”
