Zusammenfassung:	Matted fibrous material is fed between a rotatable shaft having a chopping blade mounted thereon and a rubber-covered back-up roll cooperable with the blade. Clutch and brake means enable the blade shaft to be rotated intermittently through one turn to chop off a selected length of material. An upper portion of the back-up roll is above the plane of support of feed and discharge conveyors on opposite sides of the back-up roll, and a cam on the blade shaft compresses the material before it is chopped by the blade.
