Yankee Operations Workshop: Continuous Improvement
Widening the operating window in premium quality tissue grades
North American tissue producers are facing increased competition due to changing market trends. An increase in capacity, new retail channels and the growth of private label and having creating a challenge for existing operations in both LDC and structured sheet. Market potential is higher and margin is better on premium quality products.
The production of products with premium quality is more difficult to achieve, especially while remaining cost competitive. Balancing end properties with the operating window at the yankee can cause holes, picks, breaks, short doctor blade life and issues with edge build-up.
Solenis has developed a series of robust yankee coating products which maintain machine runnability and tissue quality in spite of shifting operating conditions. Doctorability, edge control and coating uniformity are the key deliverables of the Solenis program.
Three new case histories in North American bath production will be reviewed that document the results of the new CS Series products. Benefit cases are explored for both virgin and recycled producers with different machine designs and system flows.
