Abstract

L'invention porte sur un dispositif traînant destiné à réguler l'intensité et l'échelle de turbulence de la pâte traversant le logement (12) de la règle de la caisse de tête d'une machine à papier. Le dispositif comporte un élément amont (14) muni d'un système de verrouillage (16) bloquant l'élément amont (14) par rapport à l'extrémité amont (18) du logement de la règle. L'élément amont (14) comporte également une partie aval (20) placée dans le logement de la règle et en aval du système de verrouillage. Une partie intermédiaire est placée entre le système de verrouillage et la partie aval (22), et un élément aval (24) est placé en aval de la partie aval. L'élément aval (24) est soudé par fusion à la partie aval (22).
