VB – Four Rolls Machines

Technical Features:

  • Solid steel construction;
  • Hydrostatic drive with planetary gears Stolting;
  • Top and bottom roll driven, the side rollers are driven by auxiliary gears depending of the size of the bending machine;
  • Stepless adjustment of the bending speed;
  • Hydraulically adjustable bottom roll;
  • Hydraulically adjustable side rollers;
  • Inclination of the bottom roll and the side rollers for bending of cones;
  • Hardened wear plate, conical bending facility;
  • Movable control panel;
  • Positioning and synchronization control;
  • Hardened Rollers;
  • CE Certified.

This Four-Rolls Bending Machine is characterized by high security in the bending process. Generated by the clamping pressure between the lower and upper roll the bending plate is backed up constantly, especially in the rather complex pre-bending process. The symmetrical arrangement of the side rollers, make the pre­ bending possible from both sides without changing the sheet. The normal bending process is as with the three roll bending machines by the pitching of the side roll to create the appropriate radius.

It’s surely the right machines for large productions.
