ABSTRACT:
Thin plastic flexible trailing element sheets which divide the slice chamber of a papermaking machine headbox into substantially uniform turbulence channels between the slice opening and the flow divider plate between the slice chamber and the preslice chamber of the headbox, are anchored to the plate by means of rods having greater coefficient of thermal expansion and maintain the sheets substantially free from wrinkling in the presence of heated paper stock.
