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 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 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 [...]
