Method of manufacturing a feed beater for an axial-flow crop processor in a combine harvester

A method of manufacturing a feed beater for a twin axial-flow crop processor in a combine harvester, the method comprising:

• providing a generally cylindrical rotor core;
• cutting from sheet material a pair of flat-state vane elements,
• bending the pair of flat state vane element along predetermined bend lines to form a handed pair of vane elements;
• welding the respective directional vane sections together around an edge of a substantially planar nose;
• and
• securing the vane elements to the rotor core, each one of the handed pair of vane elements comprising:
• a transverse vane section aligned parallel to a rotation axis, and
• a directional vane section having an effective edge that extends at a non-zero angle to the rotation axis;
• wherein the respective directional vane sections together form a V-shaped wedge in a central zone of the beater, wherein the wedge converges in the direction of rotation;
• wherein the directional vane sections of both said vane elements extend circumferentially beyond an apex of the wedge and abut to form the substantially planar nose.
