The motor driven roller and/or the co-rotating roller are/is provided with one or more, each in its respective peripheral slot in the cylindrical mantle surface of the roller housed O-ring of an elastic incompressible material, e.g., rubber. The O-ring bears on the peripheral surface of the adjacent roller to transmit the rotary motion by means of friction.
