Abstract
Apparatus for simultaneously severing plural parallel filter rods which issue from an extruder and move axially at the same speed has a knife mounted on a holder which is rotatable about an axis extending in parallelism with the axes of the rods. The knife holder moves along a circular path in a plane which is parallel to the axes of the rods. The knife holder and suitable guides for the rods are mounted on cranks whose crankshafts rotate about axes making a right angle to the direction of movement of the rods and causing the knife and the guides to move back and forth in and counter to the direction of axial movement of the rods. The shaft for the knife holder is rotated at twice the speed of the crankshafts and the cutting edge of the knife severs all of the rods in immediate proximity of the guides during each second revolution of the holder.
