In the case of feeding for ultrathin leaves and visco flabby materials, they are damaged by handling with fingers and other picking up tools, and paste on a truck surface in feeding. Progressive wave generated on the surface is yielded to a state of floating to the materials and conveys them on the surface as if they are washed away by the water. Elliptic vibration is generated on the surface for realization of the idea. This apparatus for the firsttrial is formed by a parallel arrangement train of combined elliptic vibrators which can be independently adjusted a phase of each other. A stretched elastic membrance is convered on the surface. It is composed of a loop shaped deflective resonator and a resonator as a reversed pendulum. It become clear that combination of a second mode in deflection and a first mode in bending suitable to feeding motion. The rationalized resonator is designed and manufacutured under a guide for determination of the shape considered the conditions, flatness over the upper plate and amplitude control of the side member actuated by a bymorph type PZT in the loop.In the basic experiment for feeding it was appeared that feeding ability depends on wetting and smoothness on the surface. Smoothness is promoted by superposition of the high frequency component to the excitation signal. The metal leaves, nikel and amorphous, have been succeeded in feeding with an eliptic veibration on the feeding surface over the resonator train.
