An apparatus for supplying volumetric metering devices especially for machines for packaging infusion products, in which the metering devices are of the type having a metering chamber within which a metering drum rotates in a discontinuous manner. The apparatus comprises a fixed hollow body facing the body of the metering device and provided with a vertical supply duct for the product to be metered, a frustoconical hollow body in the shape of a funnel rotating in an inclined manner in the fixed hollow body, with its upper, wider opening below the supply duct and with its lower, smaller opening communicating with the metering chamber in the vicinity of the metering drum, a shutter for regulating the flow of the product along the lower internal surface of the rotary funnel-shaped hollow body at least in the vicinity of its lower smaller opening, and variable speed gearing controlled by the drive means of the packaging machine so as to rotate the funnel-shaped body about its own inclined axis.
