A hopper and feeder assembly for feeding newspapers to be collated or assembled for delivery is provided which includes a reciprocating feeder device employing roller clutch and bearing wheel assemblies. The roller clutch and bearing wheel assemblies lock during frictional engagement with the lowermost newspaper in the stack during a forward feed stroke to push the newspaper forward to nip rollers. The narrow feeder device permits a sharp ridge to be formed as the nip rollers snap down to bend the lowermost newspaper in the stack over the wheel assemblies. The roller clutch and bearing wheel assemblies are mounted on a rail to provide a narrow newspaper engagement surface and corresponding narrow ridge formed in the newspaper. During the return stroke, the roller clutch and bearing wheel assemblies are able to remain in contact with the bottommost paper but the free rotating action of the tires as the newspaper is drawn forwardly by the nip rollers does not inhibit feeding, and the next newspaper in the stack is not urged rearwardly but remains static until the next feed stroke.
