  • Plate bending machine with heavy, closed machine frame and motorized back roll infeed for applications in locksmithery, steel and metal construction
  • Equipped with asymmetric roll arrangement, the machines of this series are suitable for heavy plates
  • The back roller is manually feedable, optionally the feed can also be motorized
  • The crowned rolls are made of high quality steel and are hardened and therefore also suitable for processing stainless steel
  • There are wire insertion grooves in the lower and rear rollers
  • The powerful electric motor integrated in the base frame drives the upper and lower rolls via a reduction gearbox
  • The direction of rotation is controlled by the operator via a foot switch on the separate control panel
  • An electromagnetic brake prevents overrunning and allows full control in every phase of the bending process
  • The rear roller is also motorized and a scale indicates the set position, a digital display is available as an option
  • The upper roller can be folded up to facilitate the removal of the workpiece
  • For conical workpieces, the rear roller can be adjusted to one side by loosening the coupling on the torsion shaft
  • A stable side bearing absorbs the high forces that occur when machining conical workpieces
  • Central lubrication facilitates maintenance and guarantees reliable functioning of the machine
