U.COAT ROLL COVERS
U.coat: Best running time results in the film press at Kübler & Niethammer

The Kübler & Niethammer paper factory in Kriebstein (Germany) was able to significantly increase the running time of the applicator roll in the PM1 film press through the use of a U.coat polyurethane cover from SchäferRolls.
According to Michael Moser, Production Manager at Kübler & Niethammer, the U.coat roll cover displayed very positive running time characteristics, in relation to service life, as well as coating application quality. “We are very satisfied”, reports Michael Moser. “We have achieved nearly double the running time of the conventional rubber roll covers and would certainly have been able to run longer without any problem. The coating application was very homogeneous during the entire running time.”
Kübler & Niethammer produces 85,000 t of coated offset papers per annum.

In addition to the implementation at Kübler & Niethammer, SchäferRolls` U.coat roll covers are running with great success in two additional film presses in German-speaking countries. In one application, the best results are being achieved in a combined operation with starch and coating. In another implementation, three customer-specifically, optimised HybriFlex versions in a dual layer design have already been delivered, which have excelled through extraordinary mechanical robustness and an excellent life time.
