Abstract

Dispositif pulvérisateur de liquide mouilleur pour une machine mettant en oeuvre du papier, comportant un rouleau projecteur, qui tourne autour d'un axe parallèle aux cylindres de la machine dans un carter fermé à l'exception d'une fente de sortie. Le rouleau projecteur 1 porte des nervures orientées radialement vers l'extérieur 2, qui entourent le rouleau avec une inclinaison par rapport à un plan perpendiculaire à son axe et se terminent par des lames 3 projetant par centrifugation le liquide mouilleur, et il est prévu des moyens 5 pour amener le liquide mouilleur aux nervures sous forme de gouttes. Applications aux machines mettant en oeuvre du papier, en particulier aux presses rotatives offset.Device for spraying wetting liquid for a machine using paper, comprising a projection roller, which rotates about an axis parallel to the cylinders of the machine in a closed housing except for an exit slot. The projector roller 1 carries ribs oriented radially outwards 2, which surround the roller with an inclination with respect to a plane perpendicular to its axis and end in blades 3 projecting the wetting liquid by centrifugation, and there are provided means 5 for supplying the wetting liquid to the ribs in the form of drops. Applications to machines using paper, in particular rotary offset presses.
