A system for manufacturing a positive electrode for a secondary battery includes an unwinder wound with a positive electrode base material, a first coating unit for coating an insulating material at predetermined positions about widthwise edges of the base material with respect to a transfer direction of the base material supplied from the unwinder, a first drying furnace for drying the insulating material by heating the base material coated with the insulating material, a second coating unit for coating a positive electrode slurry on the base material supplied from the first drying furnace in a region between the insulating material formed at both sides of the base material, and a second drying furnace for heating and drying the base material coated with the insulating material and the positive electrode slurry.

A dispensing nozzle for viscous material having a modified outlet is disclosed herein. The dispensing nozzle includes a first terminal portion, a second terminal portion, and a medial portion defined therebetween. The first terminal portion includes an attachment region configured to secure the dispensing nozzle to a dispensing gun. The second terminal portion includes a dispensing tip defining the outlet for the viscous material. The outlet has a quadrilateral profile in one embodiment. In another embodiment, the outlet has a square profile.

Disclosed is a coating apparatus capable of enhancing the film thickness uniformity. The coating apparatus includes a nozzle and a moving mechanism. The nozzle includes a storage chamber that stores a coating liquid and a slit-like flow path that is in communication with the storage chamber, and discharges the coating liquid through a discharge port formed at a front end of the flow path. The moving mechanism moves the nozzle and the substrate relatively to each other along a surface of the substrate. Also, in the flow path provided in the nozzle, flow resistance at the central portion in the longitudinal direction is larger than that at both end portions in the longitudinal direction.

The invention relates to a process for hot application of an adhesive composition (80) on a support (96), by means of a system comprising: a nozzle (50) for applying the adhesive composition (80), a line (88) for supplying the nozzle (50) with the adhesive composition (80) to be applied in fluid form, a mixer (30) positioned in the line (88) for the homogeneous mixture of the main components of the adhesive composition before its application; the applied adhesive composition (80) including as main components: a silylated prepolymer, a compatible tackifying resin; the adhesive composition comprising a cross-linking catalyst; the process comprising: supplying the line (88) with the silylated prepolymer separated from the cross-linking catalyst, the mixing of the cross-linking catalyst with the main components by means of the mixer (30), the hot application of the mixed adhesive composition (80) onto a support (96).

Aspects of the methods and apparatuses relate to making elastic laminates, and more particularly, methods and apparatuses for applying elastic material in a curved path onto an advancing substrate. The elastic material may be in various forms, such as for example, elastic strands and/or ribbons. Apparatuses and methods disclosed herein may also provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to the elastic material while being positioned on an advancing substrate.

A fluid application device having an applicator head, a slot die assembly and a securing mechanism for securing the slot die assembly to the applicator head is provided. 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.

A slot die assembly for dispensing a fluid onto an article includes an adapter body, a shim package and a die plate. The adapter body includes an adapter conduit configured to receive a fluid. The shim package includes a plurality of shim plates having a shim conduit disposed in fluid communication with the adapter conduit and configured to receive the fluid from the adapter conduit. The shim package further includes a connecting conduit disposed in fluid communication with the shim conduit, a reservoir disposed in fluid communication with the connecting conduit, and a slot disposed in fluid communication with the reservoir. The slot is configured to dispense the fluid onto an article. The die plate is disposed in abutting relationship to the shim package.
