ABSTRACT:
A self-oscillating roller assembly (10, 10A, 10B, 10C, 10D) with an oscillating shaft (54) mounted on translational bearings (58, 60) to slide along a stationary shaft (48) and with a rotary shaft (55) mounted to the oscillating shaft (54) on rotational bearings (80, 82) to provide rotational movement. A key assembly (62, 63, 64, 66) restrains the relative longitudinal movement between the oscillating shaft (54) and the rotary shaft (55) while a pair of springs (68, 70) provides bias to return the rotary shaft (55) and oscillating shaft (54) to a preselected home position.
