Are you worried about your Yankee? Improve your Yankee safety and avoid surface damage such as wear and chattermarks on different types of cylinders

Improve your Yankee safety and avoid surface damage such as wear and chattermarks on different types of cylinders both cast iron and metallized – with our expert advice and top-notch products.

Don’t worry. Contact our team of creping specialists who will either help you prevent chatter on your Yankee or remedy the problem you already have. The origin of chattermarks has been greatly debated, and BTG is part of the solution. We are experts on the subject and have helped many tissue makers solve their chatter problems. 

For example, BTG specialists conducted an in-depth machine and process survey and supplied a tailor-made solution for a tissue maker producing toilet paper and towel (dry crepe). The tissue maker reported greatly improved control of the coating layer on the Yankee.  With our expert advice and specifically engineered tip geometries and materials, he also substantially enhanced his cleaning strategy. As a result, he reduced downtime for machine cleaning by 50%, significantly decreased break frequency, reduced chatter and enjoyed a cleaner production tool.

In another example, a bath and napkin producing mill (dry crepe) noticed budding chattermarks after starting up production on a new Endura surface. Thanks to early intervention with BTG’s Vigilance program – a Vibration Monitoring Service – he identified and resolved the potentially damaging chatter situation before he needed to polish and/or regrind cylinders. As a result, he saved hundreds of thousands of dollars thanks to significantly longer intervals between Yankee polishings and the associated downtime involved.

In another dry crepe application--toilet paper and towel--Vigilance helped solve an important chattermark problem. With Vigilance, tailored blade designs and adapted tip materials, the mill enhanced its creping blade strategy and realized savings of €450,000.
