5 New Ways to Cut Costs and Improve Paper Quality

5 New Ways to Cut Costs and Improve Paper Quality Traditional quality measurements make it very hard to properly recognise and control trends on the paper machine – this leads to variability, over specification and ultimately higher costs. For more than ten years Aurelia Group has developed new methods and tools for characterising [...]

On-line md shear stiffness measurement

On-line MD Shear Stiffness Measurement Box strength is affected by damage in the box plant. Aurelia has shown that, on average, 30% of box performance is lost in the corrugating and subsequent conversion process. That’s a lot of over-specification and a lot of extra cost. MD Shear Stiffness is a measure of the integrity of [...]

On-line, continuous, ZD non-destructive stiffness measurement.

On-line, Continuous, ZD Non-Destructive Stiffness Measurement Aurelia is developing an on-line, continuous, single-point zd stiffness measurement suited to the technology platform already developed. This development will give a continuous measurement of zd TSI as the paper is being made, reporting zd tsi values within the reel a few times a second. This measurement will indicate [...]

ZD Non-Destructive Stiffness Measurement

ZD Non-Destructive Stiffness Measurement ZD TSI measurement – the stiffness measurement in the thickness direction of the paper sheet – completes the three engineering directions that describe paper sheet performance. Because ZD properties are so sensitive to process changes and product performance and bond damage (and its quick!) the test can give information that other [...]

Does non-destructive strength sensing have muscle?

Does non-destructive strength sensing have muscle? The question whether ultrasonic measurements of paper stiffness (sonic stiffness) can predict usual paper properties we report every day in our machine test rooms is one that is often asked. The introduction of laboratory measurements for tensile stiffness and orientation angle, have really improved the operation and [...]

Hammer that Nail

Hammer that Nail Here is an excerpt from an editorial I wrote published in the Appita Journal. The article was about trends in on-line measurement on the paper machine. Here are a few quotes about measurement which I found really thought provoking. If you have a favourite or one of your own it would be [...]

Transport – a moving feast

Transport – a moving feast Due to this blogs mentioning the importance of medium integrity or md shear performance of the medium and its effect on box performance I have had a number of questions raised about how the effect is seen and how severe it is. As a result I thought I would start [...]
