The Kadant Conformatic AL creping holder incorporates the latest technology, bringing improved blade holder performance to the tissue market. The holder is primarily designed for use in the Yankee creping position. The Conformatic blade holders are the industry standard when it comes to tissue making. The focus of the Conformatic AL model was on features that would make it easier to use and mitigate risk to the Yankee. The proprietary adjustment mechanism allows for effortless bi-directional adjustment, with enough movement to accommodate even the most extreme Yankee crowns. The modern design uses adjustment screws to maintain the desired positioning and eliminates the need for edge fingers. As the operating duty is extreme, the load capability of the conforming tube has been increased and a carbon fiber backup blade has been designed to eliminate issues caused when using stainless steel items.

Significant upgrades to the holder’s adjustability have been achieved with a proprietary adjustment mechanism, allowing for precise control of the holder profile across the entire Yankee face. The robust construction is designed for high-performance tissue machines and features a self-conforming liquid tube, a backup blade and a quick removal feature that allows the holder to be removed for cleaning and maintenance. Optional “smart” features can be integrated to provide real time process feedback such as vibration and load.

Imagine two metal parts: one is stationary and the other is running; both rubbing against each other. That is tissue creping. As Yankee speeds increase, vibrations between the rolls, Yankee and creping blade will become a more significant factor.
Tissue creping is an operation near the end of the tissue manufacturing process where the key characteristics bulk, stretch, absorbency and softness are created in the tissue.

If vibration is not controlled, the Yankee surface can be damaged and will need to be refinished by grinding, which involves downtime of three to five days. As the Yankee ages and is repeatedly ground, the steam pressure rating can be reduced resulting in lower operating steam pressure, reduced speed and less production. If the process is not stable, the Yankee can wear out in 15 to 20 years. When maintained and managed properly, the Yankee could be expected to operate for more than 30 years. Tissue creping is vitally important when the key characteristics attribute to the final product. Technically, everything can be a factor which affects the tissue creping process. The process is simple in many respects, but to get high quality tissue and meet market expectations, good creping is essential. Doctoring systems are crucial to producing a high-quality product and not damaging the Yankee shell in today’s high-speed process.
