A cutting mechanism for a composite material lay-up head comprises a plurality of blades, each blade having a variable width, and a drive mechanism to drive the blades along an axial direction to cut a respective tow of composite material. The blades are rotatable about the axial direction between a first angular position, wherein the blades sever the respective tow along a first cutting direction transversal to a longitudinal direction of the respective tow, and a second angular position, wherein the blades sever the respective tow along a second cutting direction rotated by a rotation angle to the first cutting direction.
