Abstract

L'invention concerne un dispositif, monté sur une carde ou une machine à carder du coton, des fibres synthétiques et similaires, dans lequel un cylindre débourreur (6) supporté en rotation est disposé entre un peigneur et des cylindres assouplisseurs, enlève la matière fibreuse du peigneur et la délivre aux cylindres assouplisseurs. Le cylindre débourreur possède un corps de cylindre auquel sont associées des dents de garniture dans la zone de sa surface d'enveloppe. Pour éviter, de manière structurellement simple, que la matière fibreuse se coince tout en permettant une production accrue, les dents de la garniture (6a) sont formées directement sur la surface d'enveloppe du corps de cylindre. Le corps de cylindre et les dents de la garniture (6a) sont réalisés d'une seule pièce.
