In a carding apparatus, a precarding area is provided with two lickerin cylinders having a nip area between them in which is disposed a dihedric body having an edge projecting toward the nip between the cylinders which controls the passage and transfers of the fibers from one cylinder to the adjacent cylinder while removing short staple fibers and other impurities from the web; the body is pivotally mounted to provide a clearance between its inner surface and the surface of the second cylinder through which the impurities pass to be discarded from the carding device.
