Why is tissue creping so important?


T


issue creping is an operation near the end of the tissue manufacturing process where bulk, stretch, absorbency and softness are created in the tissue. Tissue creping is vitally important when these characteristics are key attributes of the final product, and in order 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. As Yankee speeds increase, vibrations between the rolls, Yankee and creping blade will become a more significant factor. If vibration is not controlled, the Yankee surface can be damaged and will need to be refinished, typically by grinding, which involves downtime of three to five days.


Introducing:


The Conformatic™ AL Creping Holder - Kadant’s Conformatic™ AL creping holder incorporates the latest technology, bringing improved blade holder performance to the tissue market. The holder is designed for use in all Yankee doctor positions including cut-off, creping, and cleaning. This next generation model of the Conformatic blade holder focuses on features that make it easier to use and mitigate risk to the Yankee. Significant upgrades to the holder’s adjustability have


been achieved with a proprietary adjustment mechanism, allowing precise control of the holder profile across the entire Yankee face and 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.


The robust construction is designed for high-performance tissue machines and features a self-conforming liquid tube with increased load capability, a carbon fibre backup blade to eliminate issues caused when using stainless steel items 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.

bove all packaging solutions must often accomplish one task … to safely protect operators. The same applies to monitoring the cardboard feed. In this case it is essential to avoid a scenario in which an operator can reach into the machine and become injured because the opening for the material feed is empty. For this situation Pilz Automation Ltd offers a TÜV-certified solution up to PL d/Cat. 3 of EN ISO 13849- 1 or SIL CL 2 of EN IEC 62061, which can be assembled and adapted flexibly to safely monitor the feed of packaging material. Users can be confident that all the necessary safety precautions are met. Two optical sensors monitor the opening on the cardboard magazine. If there is insufficient cardboard in the magazine, the sensors will report


Therefore, creping blade holder parts should be maintained on a regular basis, inspected during each machine outage and replaced with genuine parts.


Using genuine parts ensures the highest product quality and integrity is maintained when repairing Kadant equipment. In numerous cases, non-Kadant aftermarket parts being used incorrectly have

Using the modular safety relay myPNOZ and two optical sensors the benefits are: • Can be called up pre-configured • Plug & play - wire up - ready to use immediately


• Flexible - moderate adjustments can be made if additional safety functions are to be monitored


• Easy - can be integrated into existing applications
