Abstract

L'invention concerne un dispositif sur une machine de préparation de filature, par exemple une carde, une cardeuse, un nettoyeur, une peigneuse ou similaire, dans lequel au moins un élément de cardage est disposé à l'opposé d'un cylindre garni et à une certaine distance de ce dernier et s'étend sur toute la largeur du cylindre. Ledit élément comprend un corps de support longitudinal qui comporte une partie de base et une partie arrière, une garniture étant fixée à force sur la partie de base du corps de support, et au moins une cavité servant à fournir la liaison à force. L'invention vise à fournir un dispositif qui présente en particulier une structure simple, et permet notamment de fixer facilement la garniture sur le corps de support et de remplacer rapidement la garniture. A cet effet, la cavité est mise sous vide et la liaison à force s'établit sous vide entre le corps de support et la garniture, au moins un joint étant présent entre la cavité et l'autre partenaire (garniture des corps de support).
