Abstract: An aggressive, high capacity snapping roller is formed from a multiplicity of elongated narrow rails to define a cylindrical segmented roller having stronger, more rigid and more evenly spaced blades which are integral with each rail. Individual rails include an arcuate cross section wall defining segment and an integral, angled, uniformly sharpened blade. A single row of intermittently spaced welds joins each adjacent pair of rails together and allows a low friction, unobstructed channel between blades. A method for making the roller is also disclosed.

Abstract: A self-cleaning support for a conveyor belt having a shaft with first and second ends and a longitudinal center capable of being adapted to rotate at each of the ends. The shaft is provided with a first flighting to convey material from a first point proximate the longitudinal center toward the first end and a second flight to convey material from a second point proximate the longitudinal center towards the second end, with the first and second points being spaced apart. Two annular members are mounted at the first and second points respectively both encircling the shaft and defining axial openings permitting material to pass through to their respective flights. These annular members may provide a guide for the underside of the belt by being spaced apart to receive the width of a belt guide.
