Optimization of Paper Quality

Moisture cross profile

Twosidedness

Roughness

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

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

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

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)

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

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 pretension the locks

pretensioning cylinder

precentering device

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

The Closed press(ready for operation)

How to open the press

The pretension of the locks has been taken away, the press is open

• Supply the pretensioning cylinder with 30.5 MPa for loosen the lock nut

• Turn the lock nut completely upwards

• Relive the pretensioning cylinder

All steps for TS and DS

• The Roll is now lowered onto the intermediate piece

• If damages are noticed on the guide rails they should be eliminated immediately.

• The sleeve should be lifted out of the transport case on the supplied rod.

• Don‘t pull the sleeve on the mounting device without the supplied rod

• The sleeve must be draped for at least 24 hours • It is recommended to apply oil inside the sleeve

• Shift the sleeve continously 10 mm per week

• Check both clamping disks about the shifted way and clean the moving area frequently.
