  • a disadvantage of this solution is that an additional element above the working element on the, the drum opposite side of the working element must be provided.

  • DE 10 2006 014 419 A1 discloses a system which, by supplying energy, in particular heat, attempts to achieve a countermovement to the operational deformation of the working elements.

Le tambour (4) est pourvu d'une garniture (16) faisant face à l'élément de travail (7, 8, 9). La garniture (16) du tambour (4) et l'élément de travail (7, 8, 9) définissent entre eux un espacement (22). Selon l'invention, ladite cardeuse comporte des organes (23, 46, 47) destinés à produire une force de réglage (F) permettant de régler sur toute la largeur de travail (B) l'espacement (22) entre la garniture du tambour (16) et un élément de travail (7, 8, 9) coopérant avec la garniture du tambour (16). Lesdits organes (23, 46, 47) sont disposés à l'intérieur des éléments de travail (7, 8, 9), et la force de réglage (F) est une force magnétique.
