<p>A rotor assembly (26) for an agricultural harvesting machine (10) that includes a spiral rotor cylinder (40). The spiral rotor cylinder (40) is formed from a laminar sheet that is oriented along a helix angle to the axis of rotation (A) of the rotor. The seam (46) which is formed between opposite edges of the laminar sheet winds around the cylinder (40) to form a number of full revolutions. The interior bulkhead supports and the centre shaft which are used in traditional rotor cylinders are eliminated. <IMAGE></p> |
