ABSTRACT:
An accumulating roller may be fabricated by driving a plurality of free rollers by means of a continuous belt which makes a frictional contact with the free rollers. Frictional contact between the belt and the free rollers may be enhanced by a plurality of pressure rollers disposed on the opposite side of the belt. Each end of the free rollers may be rotatably coupled to a frame by means of an eccentric linkage. The rotational coupling between the linkage and the frame is at a point which is offset and above the axis of rotation of each of the free rollers. The free roller rotates from a first position to a second position which is displaced somewhat above the first position. When displaced in the second position, the free roller makes insufficient frictional contact with the driving belt and substantially all rotational motion on the free rollers ceases.
