With the EliTop Classic for HP-GX, HP-A and P3-1 top weighting arms the pressure is applied by the leaf spring of the top roller weighting unit in the top weighting arm alone in accordance with the so-called ?stable cradle principle?. This means the applied force is divided by the structure of the EliTop body to the two top roller pairs ?delivery roller? and ?EliTe®Roller? in a given relation; 4/5 of the force is applied to the delivery roller, 1/5 of the force to the EliTe®Roller.
