Abstract

Improvements in double fabric papermaking machines comprising a pulp outlet nozzle having an open end for directing pulp under pressure and a predetermined velocity towards the opening formed by a pair of end cylinders and a pair of forming fabrics dragged around the end cylinders, characterized in that means are provided to avoid exposing the paste to the air between the outlet nozzle and the opening and that the machine includes liquid jacket means next to the nozzle wall means and having an open face directed toward the opening, and means for supplying liquid under pressure to the liquid jacket means for discharging the liquid through the open end of the liquid jacket means at a rate less than speed preset to provide a slower circulation, air-protecting liquid layer for pasta when it enters in the opening.
