Three-roll plate bender that forms plates to pipes and cones without changing rolls

摘要

MACHINES with multiple talents are always sought after due to their versatility. The 3-roll plate bending machine made by Grabener Maschinentechnik from Netphen-Werthenbach, Germany, is one such all-round talent. The smooth and fast production of pipes and half-shells, pressure vessel shells and cones is possible - without having to change rolls. This is ensured by the fully flexible adjustment of the two bottom rolls and the top roll. The bottom rolls can be adjusted individually via a hydraulic system (centre distance between 950mm and 1,500mm), the top roll can be vertically adjusted by up to 320mm, moreover, all three rolls can be set to an inclined position so as to bend conically shaped workpieces.
