Apparatus for cleaning and opening fiber tufts

摘要

A fiber tuft feeding device for a fiber processing machine includes a fiber advancing member; and an extruded, light-metal feed tray defining, with the fiber advancing member, a nip between which the fiber tufts pass in a feed direction. The feed tray which has a length extending transversely to the feed direction, includes an elongated cavity extending along the tray length. An elongated element which is resistant to bending, is received in the cavity and is substantially coextensive therewith. The feeding device further includes a support for positioning the feed tray adjacent the fiber advancing member.
