The invention discloses a kneader for the preparation of paper stuff comprising: a substantially cylindric tank (2; 120) having on the internal wall vertical ribs (21) able to interrupt the rotation of the stuff stream; a rotor (13; 130) having a vertical axis (X; Y) located inside said tank (2; 120) and provided with blades (32; 132) spiral shaped. The external edge of each said blade presents a holding wing (34; 134) which is continuous and oriented towards the bottom of the tank and said wing develops itself from the beginning of each blade, starting from the rotor part farthest from the bottom, ending almost at one turn before the end of the spiral on the bottom.
Malaxeur pour la préparation de papier, comprenant une cuve sensiblement cylindrique (2, 120) comportant sur sa paroi interne des nervures verticales (21) pouvant interrompre la rotation de la matière papier en mouvement; un rotor (13, 130) à axe vertical (X, Y) situé à l'intérieur de la cuve (2, 120) et muni de pales (32, 132) en forme de spirale. La bordure extérieur de chacune de ces pales présente un rebord de retenue (34, 134) continu et orienté vers le fond de la cuve. Ce rebord part du commencement de chaque pale, depuis la partie de rotor la plus éloignée du fond, en finissant près d'un tour avant la fin de la spirale sur le fond.
