Definitions

  • grooves 4 are shown in the forming board 1 which are all arranged parallel to one another, the grooves 4 need not be arranged in this fashion.
  • the numbers of grooves 4 in the board 1 can be varied as required.
  • the grooves 4 will lie at oblique angles to one another across support surface 2 of the board 1.
  • the adjacent grooves 4 of a series can be arranged to run obliquely to one another.
  • inserts 8 may also be provided which are the same depth as the depth of the grooves 4, effectively to blank out any grooves 4 in the board 1 which may not be required for a particular application.

Abstract

Cet élément de défloculation s'utilisant dans une machine à fabriquer du papier comprend : un élément support (1), tel qu'un marbre ou une racle, placé au-dessous d'une bande de toile de formation. L'élément support (1) présente une surface supérieure (2) définissant au moins une rainure (4) s'étendant dans le sens travers, ladite rainure (4) comprenant des éléments de retenue fixant un insert (8) étant coulissant par rapport à la rainure (4) provoquant une microturbulence dans la composition de fabrication de pâte transportée par la bande de toile de formation. La rainure (4) présente un axe longitudinal formant un angle compris entre 0,38° et 0,77° par rapport à un axe transversal dans le sens travers. Ainsi, une impulsion de pression commence dans la composition de fabrication de pâte à partir d'une seule source d'un seul côté de la toile de formation lorsqu'elle passe au-dessus du bord antérieur de l'insert puis traverse la toile le long d'une ligne de l'insert en tant qu'ondulation unique, ce qui produit une agitation et une déflocculation plus contrôlée de la composition de fabrication de pâte.
