ABSTRACT:
The invention relates to an apparatus for cutting synthetic fiber yarns into staple fibers, for which purpose the yarn is wound several times around a knife cage and rests on blades oriented radially outwardly with their cutting edges and is urged from the outside radially inwardly against these blades by means of a contact roller. The blades are held in two blade-supporting disks arranged at a mutual spacing in superimposed relationship. In order to guide the cut staple fibers radially inwardly behind the blades, and for connecting the two blade-supporting disks with each other, approximately radially oriented partitions are provided directly adjoining several of the backs of the knives, these partitions extending at least in part over the height of the knife cage along the staple fiber discharge chamber in the center of the knife cage.
