Forstner STRAIGHT Straightening & Cut-to-length
Sensitive Material Mode

Sensitive Material Mode

Not only is the coil-selector automatically controlled, but also the adjustment of the upper straightening shafts.

Whenever a new coil is selected, the upper straightening shafts will be adjusted into a new position to ensure the straightening quality.

A special sensitive material operating mode prevents start-stop-lines by the upper straightening shafts and increases the quality of the coil-line enormously. Even a single sheet can be produced without coil-set or marking of the material by the automatically adjusted upper shafts.
