Why this machine

Always clamped

The bottom roll holds the plate against the top roll the whole time — no slipping, accurate rolling.

Pre-bend both ends

The side rolls pre-bend each end without taking the plate out, leaving a minimal flat.

Easy to feed

Horizontal loading at feed level, ready for motorized roller tables.

  • Hardened rolls
  • Hydraulic safety drop-end
  • Settings from the control panel
