SchäferRolls GmbH & Co. KG, based in Renningen, Germany, was established in 1946. With by now over 300 employees worldwide, the company manufactures technologically sophisticated and high-performance roll systems and roll covers for all industries, particularly for the paper, foil, textile, printing, furniture, packaging and metal industry, as well as for machinery and plant engineering. Production facilities with a total production area of more than 30,000 m² are located at Renningen (Germany), Brnik (Slovenia) as well as at Farmington, NH and Covington, VA (USA).
The processes involved in tissue converting make a significant contribution to the end product’s key attributes – attributes customers might see as a sign of high quality. SchäferRolls presents new solutions for embossing back-up and marrying rolls which will improve the cover service life.
H.impress for the embossing process: Up to 15 °C lower heat build-up
At high machine speeds, the tissue doesn’t have much time to be embossed while located in the roll nip. As a result, the embossing rolls don’t have much time to work their magic and achieve first-class embossing quality for the complete tissue web. Add to that the increasing complexity of embossing patterns, with different depths of micro and macro embossing, and it’s clear that embossing back-up roll covers have their work cut out of them. To meet these high demands, our embossing back-up roll covers are designed with particular attention to the wear, elasticity and resilience properties of the cover material. With H.impress (fig. 1), SchäferRolls introduced a roll cover with excellent resilience properties and very low compression set. The low heat build-up and the increased mechanical resistance allow the machines to run reliably and according to plan while maintaining a consistently high embossing quality.
