Abstract

L'invention concerne un segment de peigne pour peigne circulaire de cylindre de peignage servant au peignage du coton, qui comprend plusieurs rangées de dents (6; 6a) disposées les unes à côté des autres en direction d'un axe de rotation (3) du cylindre de peignage (2), lesdites rangées de dents comportant un sens périphérique (10 et plusieurs dents (7) disposées respectivement les unes à côté des autres dans le sens périphérique de chaque rangée de dents (10). A l'état monté sur le cylindre de peignage (2), le segment de peigne (5) peut tourner autour de l'axe de rotation (3) dans un sens de rotation (4), les rangées de dents (6; 6a) étant disposées de manière oblique par rapport à l'axe de rotation (3), de sorte que le sens périphérique des rangées (10) et le sens de rotation (4) forment un angle d'incidence α. Au moins un écarteur (8, 9; 8a, 9a) est prévu entre deux rangées de dents (6, 6a) adjacentes et un écart de rangée de dents (D1; D2) entre deux rangées de dents (6, 6a) adjacentes, mesuré perpendiculairement au sens périphérique des rangées (10) est modulé de manière cyclique.
