Abstract

Producing a paper web by distributing high- and low-consistency stock streams over common sections across the machine width, mixing the streams in each section in a variable ratio, feeding each mixed stream onto a wire through a headbox, and using the mixing ratio in each mixed stream as a control variable for controlling the transverse grammage profile of the web, comprises adjusting the pulp/filler ratio in the low-consistency stream before distributing it so that the filler content of the paper web can be adjusted independently of the grammage. An independent claim is also included for apparatus comprising devices for performing the above operations.
