A method and apparatus for making an absorbent composite from continuous tow is disclosed. The method and apparatus includes the steps of or means for spreading a crimped tow; de-registering the crimped tow; shaping the de- registered tow to a substantially rectangular cross-section; and distributing a particulate onto the shaped tow. The method and apparatus also include the step of or means for introducing a crimped tow from a bale, wherein the tow's travel through de-registering, shaping, and particulate distribution, defines a vertical plane and the bale is located off the vertical plane.

L'invention concerne un procédé et un appareil servant à fabriquer un composite absorbant à partir d'une étoupe continue. Ce procédé consiste : à étaler une étoupe frisée ; à décaler les frisures de l'étoupe ; à donner à l'étoupe aux frisures décalées une forme présentant une coupe transversale sensiblement rectangulaire ; et à répartir une matière particulaire sur ladite étoupe. Le procédé selon l'invention consiste également à acheminer une étoupe frisée à partir d'une balle, l'acheminement de l'étoupe vers les étapes de décalage, de mise en forme et de distribution de matière particulaire définissant un plan vertical, la balle étant disposée en dehors de ce plan vertical. L'invention concerne également les différents moyens composant l'appareil de fabrication de composite.
