1-14. (canceled)
A two-component delivery system for use in delivering a mixture of a first and second material between a supply part, which supplies the first material at a mixing point, and a circulating part, which circulates the mixture to be transferred to another device, the system comprising:
- a shaft which rotates;
- and
- a delivering wing unit on the shaft having a first surface and a second surface, where the first surface is shaped to push the first and/or second materials in a first direction from the mixing point to the circulating part according to the rotation of the shaft and the second surface is shaped to push the first and/or second materials in a second direction from the circulating part to the mixing point according to the rotation of the shaft.
