The inner cutter (12) comprises a rigid unit and the outer cutter (13) is formed as a triangular frame with two cutting parts on which the edges are located. The cutting parts are sprung in relation to each other, and have free outer end parts. - The free outer end parts, in the unloaded state, cross one another, and when cutting occurs are successively pushed from one another so that their edges finally cross each other at the cutting point. |
