ABSTRACT:
Flighting for screw conveyors of improved construction and resulting in better wear characteristics and carrying capacity is provided through the use of cold roll manufacturing and a roller which forms the flighting with a shape which moves some of the material being conveyed away from the outside peripheral edge of the flighting and thereby distributes wear over a larger portion of the surface of the flighting.
