Conditioning roll biasing mechanism

Abstract From the Canadian patent

A biasing mechanism for a roll-type conditioning apparatus having a pair of generally vertically spaced counterrotating conditioning rolls in which the upper roll is biased toward engagement with the lower roll is disclosed wherein a torsion bar interconnects the opposing ends of the upper roll such that any movement of either end of the upper roll away from the lower roll effects a twisting of the torsion bar to increase the biasing force exerted thereby on both ends of the upper conditioning roll. The torsion bar is connected to a mounting mechanism which includes a hub assembly pivotally connected to the frame of the conditioning apparatus on a pivot arm movably mounting one end of the …
