ABSTRACT:
A flight section for mounting at the feed end of an auger comprises an intergral moulding from a resilient elastomeric material such as natural rubber which includes a central sleeve portion and an outer flight. The sleeve has an inner surface for engaging around a shaft with the surface defining a part cylindrical portion and a flat portion by which torque is communicate from the shaft to the sleeve portion while allowing slippage to occur by distortion of the resilient sleeve portion when the torque exceeds a predetermined maximum. The flight extends over 360.degree. and is shaped so that it increases in transverse width or thickness as it approaches the outer edge thereof thus defining a flat band around the outer edge. This acts to define a curved surface facing the material to be fed which cups the material and reduces slippage.
