Abstract:
A sheet accumulator comprising:(a) a rotatable circular device having an outer perimeter; (b) a circular guide having an inner periphery, proximate to the outer perimeter of the circular device, for forming a substantially circular channel; (c) a set of one or more rollers, adjacent to the outer perimeter of the circular device, for forming a nip with the circular device that urges sheets of paper to enter the channel one by one, and for causing the entered sheets to move in a circular motion when the circular device is caused to rotate; and (d) a set of one or more stops, adjacent to the circular channel and remote from the nip, movable from a first position, blocking the circular channel so as to stop the circular motion of the entered sheets thus forming a stack, to a second position removed from the circular channel so as to allow the stack of sheets to exit the accumulator.
