Abstract
The invention relates to devices for supplying fibers to a unit for spinning loose or free fibers. Such a device according to the invention comprises a feeding device including means for holding back a sliver of fibers and a fiber-separating device disposed in a hollow enclosure and constituted by a rotary drum, the surface of which is made up by elements of narrow fiber-separating ridges which each extend in a circumferential direction in a plane perpendicular to the drum axis over only a part of the drum periphery; two of said elements successive in the axial direction are angularly staggered while narrow and deep grooves separate in the axial direction at least a part of said ridge elements from one another; the invention is generally applicable to feeding devices of spinning units of free or loosened fibers of all kinds.
