A COMMON PROBLEM FOR TISSUE MAKERS – CHATTER

CHATTER – A PROBLEM AT THE CREPING DOCTOR RELATED TO DYNAMIC INSTABILITY
Dynamic instability caused by Fric;on:
The variaMon of the fricMon coefficient with the relaMve speed can create dynamic instability. Tribology is a great part of this instability, as we are facing a sMck-‐slip problem.
Dynamic instability created by Regenera;ve Effect:
VibraMon gets affected by the groove created by the creping blade in the coaMng layer during the previous Yankee turn. This groove influences the creping efforts.
High frequency vibra;ons:
Lihle crashes created in the creping blade by the creping process can originate marks in the Yankee.

INSTABILITY – CAUSED BY MULTIPLE RISK FACTORS
Both staMc and dynamic phenomena bear extremely complex mathemaMcal modelizaMon as they are depending in many process parameters.
Chaher is a complex, mulM-‐disciplinary and cumulaMve phenomenon.

Tissue makers take mulMple decisions on chaher-‐criMcal parameters everyday
Those decisions affect process-‐safety, machine-‐ efficiency, producMvity & costs
Results of those decisions are usually only measured aker days/weeks
We need to measure the results of decisions
IN REAL TIME to act in Mme
Consequences of process decisions are cumulaMve
A PROCESS-DECISSION
STEERING TOOL IS NECESSARY

SUMMARY:
Tissue World 2015 – Booth No. F250
A harmful consequence of pushing the limits in search of producMvity is
Yankee chaher
LanMer’s iCrepe® is the only tool that detects chaher early enough that major damages can be avoided
LanMer’s high dampening crepe holders and special polishing blades reduce the effect of chaher and improve crepe-‐producMvity
Tissue makers, Yankee reliability experts and Mssue consultants can now have the best set of tools to steer process-‐decisions and opMmize crepe performance
You can get any expert to help you with this tool, because it is accessible worldwide over the internet
