Optimization of Paper Quality
Moisture cross profile
Twosidedness
Roughness
![Page 10: 0403000 press sectionr](https://reader038.vdocuments.site/reader038/viewer/2022110306/5554831fb4c9050f348b4fe9/html5/thumbnails/10.jpg)
Moisture Cross Profile
It is possible, that the moisture cross profile is not satisfying after the wet end of the machinePossible reasons: HP/LP-Nozzles blocked Felt condition uneven Catch pans are overflowing Uhlebox dewatering is uneven Hydrostatic press shoe hydraulics are malfunctioning Press shoe is damaged Felt design unsuitable for machine Optimize void volume of sleeve
![Page 11: 0403000 press sectionr](https://reader038.vdocuments.site/reader038/viewer/2022110306/5554831fb4c9050f348b4fe9/html5/thumbnails/11.jpg)
Twosidedness and Roughness
Twosidedness and Roughness can be influenced slightly through shifting the press loads from the first to the second press or visa versa
The main influencing factor though is the design of the press felt: All successful machines have gone through an optimisation process In this process a compromise between surface characteristics, dry content and runnability has to be found
![Page 12: 0403000 press sectionr](https://reader038.vdocuments.site/reader038/viewer/2022110306/5554831fb4c9050f348b4fe9/html5/thumbnails/12.jpg)
Optimization of Press Section: General Hints
Check felt tension with hand measurement device
Use HP-shower for felt conditioning according your own
experience
Use schedule for HP-shower for roll cleaning
Adjust vacua in uhle boxes according felt life time
![Page 13: 0403000 press sectionr](https://reader038.vdocuments.site/reader038/viewer/2022110306/5554831fb4c9050f348b4fe9/html5/thumbnails/13.jpg)
Trouble shooting – Dryness after Press too low
Possible causes:
Dryness after Former too low Temperature of the pulp too low Pulp too strong beaten Deflector Stripes not in ideal position Line force too low Steam blow box not in operation Press roll storage volume dirty Problems with the felts (see next slide)
![Page 14: 0403000 press sectionr](https://reader038.vdocuments.site/reader038/viewer/2022110306/5554831fb4c9050f348b4fe9/html5/thumbnails/14.jpg)
Trouble shooting – Dryness after Press too low
Possible causes (Felt & Feltconditioning):
Structural resistance of the felt too high To high re-moisturization Needleing inhomogeneous Too fine felts Too light basis weight of felt End of felt life time New felt: Nip-dewatering has not startet Filler content too high in the felts
![Page 15: 0403000 press sectionr](https://reader038.vdocuments.site/reader038/viewer/2022110306/5554831fb4c9050f348b4fe9/html5/thumbnails/15.jpg)
Trouble shooting – Edge Trim follows the Felt
Possible causes:
Felt too smooth in the edge section Edge moisture too high Pick-up suction roll holes plugged in the edge section Edge trim too narrow Trim-Guard settings false

How to close the press
• Insert all locks according to marking on the bearing support
• Raise the NipcoFlex Roll with the pretensioning cylinders (Pressure for tightening 27.7 MPa)
• Lock the pretensioning cylinder with the lock nut (turn down)
All steps for TS and DS
The press is now closed and the locks are pretensioned
• Insert the locking clamps
