PURPOSE:To provide a device comprising specific components, capable of stably and accurately feeding a doubly inner wrapping material, a triply inner wrapping material, and an outer wrapping material, and capable of making the whole of the device compact. CONSTITUTION:A doubly inner wrapping material A, an outer wrapping material B and a triply inner wrapping material C are fed into a pair of laterally symmetrically disposed hoppers 10, 10a and into a central hopper disposed between the hoppers 10, 10a. A pair of screws 11, 11a disposed under the hoppers 10, 10a at mutually tilted and faced angles, and a screw 11b disposed under the central hopper 10b at a forward-tilted angle are rotated to rotate and drop the inner wrapping material A, the outer wrapping material B and the inner wrapping material C, respectively. Thus, the inner wrapping material A, the outer wrapping material B and the inner wrapping material C are fed into the doubly inner wrapping material nozzle in a superposition 60, into a space between the nozzle and a cylindrical gear equipped with feeding blades, and into a nozzle for the triply inner wrapping material, respectively. Finally, the gear is rotated to wrap the inner wrapping material A containing the inner wrapping material C with the outer wrapping material B. |
