Abstract:
Provided is a slot die with variable nozzles. The slot die with variable nozzles, which applies ink on a substrate to perform a coating process, includes: a first body having a cavity configured to accommodate ink supplied from the outside; a second body spaced apart from the first body in a transfer direction of a substrate or a direction opposite to the transfer direction; a shim plate coupled between the first body and the second body and having an discharge port configured to communicate with the cavity and discharge ink accommodated in the cavity toward the substrate; and a plurality of variable nozzles disposed at a lower end of the first body or the second body in a width direction of the substrate so as to be adjacent to the discharge port, wherein each of the plurality of variable nozzles is independently driven according to a state of the ink coated on the substrate and adjusts a partial discharge amount of the ink discharged from the discharge port by changing a partial area of the discharge port at an arrangement position thereof.
