Rollforming machines to form a flat metal sheet to a constant section product. Depending on the profile to be produced, 5 sizes of standard profiling heads are available.
5 Sizes of standard rollforming heads
- Tapered roller bearings for heavy loads and very long life
- High rear alignment precision ±0.1mm
- Massive cast structure for high rigidity
- Quick opening of the front arch for rolls shift in less than 2 minutes
- Quick change of a complete raft

Description
Cardan rollformer
- Traditional concept which allows to clutch each shaft independently with a special speed ratio
- Full vertical adjustment range
- Quick cardan plugging to shift the raft
Gear or chain rollformer
- Machine cost reduced
- Very fast raft shift with instant coupling to the engine
- Small footprint
Dual rollformer
- 2 independent rolls unities, width setting in few second, ddapted for shelves and panels
