Abstract:
1. An apparatus for providing coating materials, one at a time, onto a substrate perpendicularly so that coating materials are in order vertically, the apparatus comprising: an input device comprising a shell and at least one barrel in communication with the shell so that the barrel provides an ingredient of each of the coating materials into the shell; a rotational die assembly comprising: a rotational die in communication with the tube so that each of the coating materials travels into the die from the tube, wherein each of the coating materials travels in a radial direction in the rotational die; and a die-driving motor operatively connected to the tube so that the motor drives the rotational die via the tube, wherein a tangential speed on the periphery of the rotational die is identical to a linear speed of the substrate so that each of the coating materials is perpendicularly provided onto the substrate; and an extrusion device comprising at least one screw for mixing and transmitting each of the coating materials in the tube and a screw-driving motor for driving the screw; wherein an area of the substrate for receiving each of the coating materials from the rotational die is 1% to 99% of the entire area of the periphery of the rotational die.
