A chopper assembly for cutting filaments in a strand into short lengths, comprising two rolls (1,4) being rotatable in opposite directions and having a pinch where the rolls (1,4) contact each other. At least one of the rolls (1,4) is provided with cutting blades (2,5) at its cylindrical outer surface. Means (15) are present for guiding said strand to said pinch where the filaments of the strand are cut. Both axes of rotation 16,17) of the rolls (1,4) are parallel to the tangential plane through said pinch and make an angle (a) with each other, so that the cutting blades (2,5) move in axial direction with respect to each other in the pinch. |
