The paste feeding apparatus is equipped, within a cylindrical container having a paste feeding opening at its lower end, with a spiral pump composed of a vertical mantle tube having a paste inlet and a paste outlet, which are spacedly formed at lower and upper positions, respectively, and a screw shaft provided coaxially within the mantle tube; a drive motor connected to the screw shaft; and a piston moving up and down in an annular space in the container. A raking blade which is connected to the screw shaft and serves to rake a paste in the paste inlet of the mantle tube may be provided. The paste feeding apparatus is composed of a drive section and a pump-container section detachably installed thereto. According to the paste feeding apparatus, the kneading of a paste, the adjustment of its viscosity and the control of its feed rate can be stably achieved with high precision, and hence high reliability can be attained.
