A unit for disintegrating a sliver into spinnable fibers fed to a spinning machine comprises a fiber-disintegrating drum with serrations generating a cylinder on rotation of the drum. A first smooth feed roller guides the sliver to the cylinder and defines therewith a first and second wedge-shaped space on the sides of which the serrations approach and depart from the first feed roller during a rotation, and this feed roller may be adjustably spaced from the cylinder. A second clamping and smoothing feed roller is disposed in the first wedge-shaped space and defines a nip with the first feed roller, the feed rollers being operable to feed the sliver through the nip to the serrations. A cover extends into the second wedge-shaped space and is closely spaced from the first feed roller and as closely as possible from the cylinder. A first pair of pinch rollers feed the sliver to the nip and a second pair of pinch rollers feed the sliver to the first pair of pinch rollers, the first pair of pinch rollers being driven at a higher speed than the second pair of pinch rollers, and the feed rollers being driven at a higher speed than the first pair of pinch rollers.
