Abstract [en]

In the present study, we report results from in-situ investigations of the forming process performed in the roll-blade section of a pilot machine. Direct measurements of the drainage pressure along the forming zone were obtained using a miniature fibre-optic pressure transducer inserted into the flow through the headbox jet. High-speed imaging of tracer particles using a transmitted light setup was performed to in an attempt to obtain direct measurements of the local stock speed. By replacing one section of a ceramic blade with a quartz glass piece, access was also obtained to the region on top of the blade. The combined picture that emerges from these measurements is that the pressure distribution and the velocity field along a twin-wire forming zone is significantly more complex than usually assumed, and that much remains to be understood about the dynamics of twin-wire forming.
