Patent

CA 2476233

A twin-wire paper machine is provided with a white water recovering means (20) for recovering white water (15) discharged to the opposite roll side upstream of a pressure element (30), thereby inhibiting the white water (15) discharged to the opposite roll side from interfering with the pressure element (30), thus preventing damage to the pressure element (30) due to the collision of the white water (15) during water discharge, and making it possible to produce paper with uniform fiber distribution having no paper defects.

La présente invention concerne une machine à papier à double toile avec un organe de récupération (20) des eaux blanches destiné à la récupération des eaux blanches (15) évacuées vers l'amont du coté du rouleau opposé d'un élément de pression (30), empêchant ainsi les eaux blanches (15) évacuées du côté du rouleau opposé d'interférer avec l'élément de pression (30), et évitant ainsi de détériorer cet élément de pression (30) du fait de la collision des eaux blanches (15) pendant l'évacuation des eaux, ce qui permet de produire un papier sans défauts avec une répartition de fibre uniforme.
