Abstract
A retard assembly for use in a friction retard separator feeder has a retard member, a support member for supporting the retard member, the retard assembly being mountingly engageable with a pivoting support frame for supporting the retard assembly at a first end of the pivot support frame and having a pivot point at its opposite end and substantially remote from the first end, the retard member support member having at least one mounting hub for mounting a locating pivot pin, which is engageable with the first end of the pivoting support frame, the retard member support member including at least one energy absorbing damping pad on the at least one mounting hub to absorb vibration of the retard pad between the retard member support member and the pivoting support frame when they are engaged, the energy absorbing damping pad being of a hardness sufficient to maintain an interference fit between the at least one mounting hub and the pivoting support frame to resist a permanent set.
