Direct roller drive

The direct roller drive ensures automatic speed compensation between the different rollers; this solution also offers integrated overload protection.


Best results for thin & thick sheets

The special single roller adjustment of the HAEUSLER RI series enables our customers to optimally straighten both thin and very thick sheets.


Highest durability

By using very large dimensioned rolls, the so-called Hertzian pressure is reduced; this increases the service life of HAEUSLER straightening machines enormously.
