Multi-slot die coater

A multi-slot die coater comprising:

• a lower slot and an upper slot,
• a lower die block, an intermediate die block positioned on the lower die block such that the lower slot is formed between the intermediate die block and the lower die block, and an upper die block positioned on the intermediate die block such that the upper slot is formed between the upper die block and the intermediate die block;
• a first manifold provided in the lower die block, the first manifold in which a first coating solution is received, the first manifold being in communication with the lower slot, and a second manifold provided in the intermediate die block, the second manifold in which a second coating solution is received, the second manifold being in communication with the upper slot;
• and
• a first bolt fastened to a contact surface between the upper die block and the intermediate die block,
• wherein the lower die block, the intermediate die block and the upper die block include a lower die lip, an intermediate die lip and an upper die lip that form front ends thereof, respectively, and
• wherein when a distance from the intermediate die lip to one end of the second manifold is A, a distance between one end of the second manifold and the other end is B, and a distance from the other end of the second manifold to an axis of the first bolt is C in an order of how far it is away from the intermediate die lip, C/(A+B+C) is 0.28 or less,
• wherein the front end of the lower die lip, the intermediate die lip, and the upper die lip are parallel to a vertical plane of a discharge end of the multi-slot die coater.
