Disclosed is a slot die coater adjusting device, which adjusts a slot die coater including a lower die having a lower discharge hole for discharging a first active material slurry and an upper die having an upper discharge hole for discharging a second active material slurry, to adjust a distance between the lower discharge hole and the upper discharge hole by allowing the upper die to move. The slot die coater adjusting device includes pressing block assemblies respectively provided to both longitudinal sides of the slot die coater and fixed to the upper die; a linear motion (LM) guide disposed at a lower portion of the pressing block assembly and connected to the pressing block assembly to guide a movement of the pressing block assembly; a servo motor configured to give a power for moving the LM guide; and a reducer connected between the servo motor and the LM guide.

The present invention relates to a double slit coating die, and an electrode active material coating apparatus comprising same, the double slit coating die comprising first to fourth blocks which are positioned sequentially adjacent to each other, and having a structure in which the positions of the first and second blocks can move in a direction tilted at an angle θ with respect to the interface between the second and third blocks. The present invention has the effects of preventing slip surfaces between blocks constituting the die from spreading apart, and reducing offset in a coating process.

The present invention relates to electrode slurry coating apparatus and method, the present invention ultimately allowing the process efficiency to be increased and rate of errors to be reduced when double-layer structured active material layers are formed by temporally adjusting the height of first and second discharge outlets through which active material is discharged.

Provided herein is an improved spin coating system and a method of using the spin coating machine to produce an optical article. The system includes at least one dispensing arm assembly. The holder assembly is moveable along a substantially vertical axis. The dispensing arm assembly has a base and at least one arm having a first end and a second end and is moveable along a horizontal axis. The at least one arm is operably coupled to the base at the first end and operably coupled to at least one applicator at the second end, and the applicator is capable of being positioned along the substantially vertical axis. The method includes depositing a primer layer onto a lens using the dispensing arm assembly, followed by a hard coating, and drying and cooling the substrate using a drying/cooling station that is positioned substantially along the substantially vertical axis.

There is provided a multi-slot die coater including a manifold for a uniform flow of an electrode active material slurry without stagnation. The multi-slot die coater of the present disclosure includes a first manifold in which a first coating solution is received and a second manifold in which a second coating solution is received. The first manifold is a chamber of an inwardly recessed shape, and includes a first surface and a second surface having different angles to a lower slot at a location close to the lower slot, and the angle of the first surface closest to the lower slot is formed at a level of 30˜70% of the second surface following the first surface.

A method and apparatus for applying or dropping granules onto the asphalt coated surface of a moving sheet in shingle manufacturing is disclosed. The method includes sharing each drop between two or more blend rolls with a subsequent blend roll or rolls applying a partial drop directly on top of partial drops already applied by a first blend roll or rolls. High production speeds can be accommodated since each roll can be operated at slower rotation rates and with slower acceleration and deceleration requirements than would be required if the full granule drop were applied during the same time interval with a single blend roll.
