How to prepare samples for Tapio Analysis Service

Please obtain all samples from a reel which has been produced under normal & “steady state” operating conditions. Particularly if the data provided does not properly match the operating conditions can cause problems when analyzing the results.

MD Samples

The machine direction (MD) sample rolls are usually obtained at the winder or re-winder, from close to the ends of a reel or from a cross direction location that is known to be causing the problems.
The MD sample roll can be up to 75 cm in diameter
The MD sample roll can be up to 25 cm wide (15 to 20 cm width recommended)
The sample should be on a standard 3” standard core.
If you cannot prepare a small enough roll on a 3" core, we have partners available for cutting and winding

CD Samples

For the cross direction (CD) analysis, at least 20 full width strips from the same parent reel are needed to calculate a stable average CD profile.
CD samples can be hand cut across the reel.
Make sure that each strip is wide enough to be cut into 20 cm strips in true perpendicular CD direction. Recommendation is to cut ~40 cm wide strips.
Always clearly note the drive (DS) and tending side (TS) on the samples, as well as top and bottom (wire and top) side.
At Tapio laboratory, the strips are cut and taped into a “mini reel” on a standard 3” core for measurement, using a sample cutter specifically developed by Tapio for this purpose.

Production line data

Describe the problems you have been experiencing with the machine lately and any specific area you would like to have us focus our analysis.

Note the sample grade and nominal basis weight supplied for this test.

If possible:

For MD analysis, please collect rotating frequencies or diameters of rolls, felts, pumps and wires in the machine.

For CD analysis, please provide CD actuator spacings

To achieve an accurate total ash measurement, please specify either the types of fillers and coating formula or the nominal ash level.
