Variation of CD Shrinkage on Paper Machines
In common with many other materials, paper tends to shrink as it dries. Although every attempt is made to restrain paper, some shrinkage occurs on all paper machines in the direction perpendicular to that of manufacture and this shrinkage is always much higher at the edges of the machine than in the centre. Measurement of the profile of this cross-machine shrinkage is possible using the fast Fourier transform to locate and measure periodic elements imprinted by the filtration fabrics used during formation of the paper web.
This project will build on the research group's world-leading experience of measuring and analysing paper machine CD shrinkage profiles to investigate in detail aspects of shrinkage profile shape.
The project will involve use of computers for image and data analysis but specific experience is not required.
