The slot die assembly includes a die extruder comprising one or more fluid input ports configured to receive a fluid from the applicator head, a shim positioned adjacent to the die extruder, and a plate positioned adjacent to the shim on a side of the shim opposite from the die extruder. The securing mechanism includes a securing component at one of the applicator head and the slot die assembly and a corresponding securing component at the other of the applicator head and slot die assembly.
Method of manufacturing porous separator comprising elastic material, porous separator manufactured by the method, and secondary battery comprising the separator
Disclosed is a method of manufacturing a porous separator including an elastic material, and a separator manufactured by the method. The separator includes an elastic material being uniformly dispersed in a polymer at a weight ratio of 40:60 to 5:95, and a value of elongation at break in a low tensile strength direction at room temperature is greater than or equal to 250%. In addition, the method of manufacturing a porous separator includes forming an extruded sheet by extruding a mixture of a polymer and an elastic material at a weight ratio of 95:5 to 60:40, forming a film by annealing and stretching the extruded sheet, and forming a porous separator by heat setting the stretched film. Accordingly, a thermal shrinkage ratio of the film is reduced and an elongation at break is greatly increased, to provide a porous separator with improved stability.
SHEET EXTRUSION DIE
An extrusion die includes a plurality of studs, a tuning assembly and a restrictor member. The tuning assembly comprises a wedge member, first and second adjustment members, and an adjustment control having a rotatable single point adjustment member. The wedge member is coupled to first ends of the studs and includes a first and second plurality of channels within. The first and second adjustment members have a plurality of protrusions, each of which is positioned within a respective one of the first and second plurality of channels. The restrictor member extends in the longitudinal direction and is coupled to second ends of the studs. Rotation of the single point adjustment causes each of the protrusions to move within each respective channel forcing the wedge member, the studs, and the restrictor member to move in a direction that is substantially perpendicular to the longitudinal direction.

METHOD FOR FORMING RESIN FILM
Provided is a method for forming resin film capable maximizing the effective width of the resin film while suppressing neck-in and so increasing the material utilization. The method includes: drawing molten resin extruded downward from a die exit by a cooling roll; blowing air to both ends of the molten resin from an air-blowing nozzle to cure the both ends of the molten resin while cooling the molten resin on a surface of the cooling roll for solidification. For an effective width of the resin film to be formed having a thickness in a predetermined thickness range, a target effective width is set. An amount of air to be blown and a distance from the air-blowing nozzle to the molten resin are set to form the resin film having an effective width of the target effective width or more. The resin film is formed while blowing air under the conditions.
