Straightening is the core area of the coil line technique.It equalizes the deformation of the metal belt that occurs during winding. The ideal straightening device for eachapplication is determined by
- the number
- center distance of the straightening rollers
DREHER identifies these parameters with a special calculation tool and, with these results, we select the optimal straightener for you.
The requirments in this area has changed in the last years because of hight-strenght materials.
With this in mind we offer you different solutions for your particular requirements:
- Universal straightener
To manufacture basic structure parts
- 4-high straighteners
For superior structure parts and materials with middle to high elastic limit
- 6-high straighteners
The high-end technique for straightening of visible parts and exterior parts
