ABSTRACT OF THE DISCLOSURE A slitter cuts flattened pieces of fibrous plant material into longitudinal strips. The slitter comprises a pair of opposed rotary members each having a plurality of annular cutting teeth. Each cutting tooth comprises an outer annular cutting edge, a radial rear race, and a non- radial front face. The cutting teeth of the two rotary members overlap radially to engage opposite sides of a plant piece and completely cut through the plant piece and slit same into strips. The teeth define cells in which the strips are rotated while being fed. front faces of the cell are arranged opposite each other and spaced apart at the point of maximum overlap to define a cell width corresponding to the thickness of the plant piece to grip the sides of the respective strip and positively advance and discharge same. In a modified embodiment, the teeth include replaceable cutting inserts which are removably attached to base members and extend radially there beyond. This arrangement increases the amount of cutter overlap without reducing the size of the cells. The inserts are attached to the base members by solder and are removed therefrom by melting the solder.
