Work examples

Conical shape work   Work

Conical shape forming is possible with attachment.


  • The machine employs a backup roller for compensating the bottom rolls of small diameter and fitting the top roll deflection. (Adjustment Mechanism)
  • The machine makes the straight portion of the plate ends extremely smaller than the conventional 3-roll machine does, owing to the smaller diameter bottom rolls and also the closer axes between rolls.
  • For high accuracy edge bending
  • High production model that thin and long work can be processed at once.
  • 3 rolls driving by hydraulic motor
  • Rolls are quenched and grinded, so stainless steel or aluminum plates can be processed without any damages on surface.
  • High tensional plate or 6mm thickness steel plate can be processed in small diameter which urethane roll is impossible.

Edge bending accuracy can be also increased by forming ring with suitable with work bending diameter. Edge bending accuracy can be also increased by forming ring with suitable with work bending diameter.

  • The data shown above is tested with SS400 (steel), therefore it can be changed depends on different materials. Please contact us for more information. Specifications may be subject to change without prior notice.
  • Please prepare the following information for inquiry.
    Material, production size(minimum maximum), production amount(per day), work sheet size (thickness, width, length,), previous process, accuracy of roundness.

Bending roll and shrinking processing machine (PAT.)

Bending roll and shrinking processing machine (PAT.) : After bending roll processing, adding the shrinking press to increase the roundness accuracy. Also accuracy of jointing point is improved.

Feeding single sheet automatically by vacuum pad / Roll forming / Automatic discharge / Shrinking press

After bending roll processing, adding the shrinking press to increase the roundness accuracy. Also accuracy of jointing point is improved.
