摘要

The cutting bar for a filament cutter, where the cutting filaments are attached to a cutting head, has cutting zones (13,15) with a thinner center section (14) between them with a recessed cylindrical or polygonal cross section. The center section fits into the cutting head, and at least one side of the cutting zones is tapered into a cutting edge.
