Apparatus for severing a tow of crimped textile fibers has an outer cage and an inner cage. The inner cage has an annulus of idler rollers extending in parallelism with the common axis of the cages, and the outer cage has an annulus of elongated knives whose cutting edges spacedly surround and face the rollers. A tow of textile fibers is fed axially into the inner cage and is guided radially outwardly by an eyelet in the inner cage to enter a ring-shaped compartment between the knives and the rollers. A motor drives the inner cage or the outer cage to thereby convolute the tow in the compartment whereby the driven cage adds convolutions in the region immediately adjacent to the rollers and such convolutions cause the outer convolutions to expand toward and to be severed by the cutting edges. The severed fibers are withdrawn by a suction chamber which surrounds the outer cage. An endless belt can be trained over the rollers and over several pulleys in the interior of the inner cage so that a looped portion of the belt spacedly surrounds the eyelet and a cylindrical portion of the belt surrounds the rollers and supports the innermost convolution of the tow in the compartment.
