Systems and methods in which dot-like portions of a material (e.g., a viscous material such as a solder paste) are printed or otherwise transferred onto an intermediate substrate at a first printing unit, the intermediate substrate having the dot-like portions of material printed thereon is transferred to a second printing unit, and the dot-like portions of material are transferred from the intermediate substrate to a final substrate at the second printing unit. Optionally, the first printing unit includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred in the individual dot-like portions from the donor substrate onto the intermediate substrate at the first printing unit. Each of the first and second printing units may employ a variety of printing or other transfer technologies. The system may also include material curing and imaging units to aid in the overall process.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

A web adhesive application device, adhesive application method, and the cardboard sheet manufacturing device are provided with: an adhesive liquid tank for storing an adhesive liquid; an adhesive application roll is configured for transferring the adhesive liquid to an adhesive application region adjusted according to a paper width of a bottom liner board to be glued together with a single face cardboard sheet; a doctor roller for adjusting the adhesive liquid to a set film thickness; scraping members in pressured contact with the surface of the adhesive application roll on the upstream side of the nip section with the doctor roller; and damming members in contact with the surface of the adhesive application roll on the upstream side of the nip section with the doctor roller in the rotation direction and on the downstream side of the scraping member contact positions in the rotation direction.

The present invention provides an adhesive layer coating unit configured to continuously apply an adhesive layer having a first width in a longitudinal direction of a first separator. The adhesive layer coating unit comprises: a transfer roller configured to support a bottom surface of the first separator and transfer the first separator; a discharge roller configured to transfer the first separator, which has passed through the transfer roller, in conjunction with the transfer roller while supporting a top surface of the first separator, wherein a coating groove having the first width and a closed curve shape is formed in a circumferential surface of the discharge roller; and a coating member configured to inject an adhesive into a space between the discharge roller and the top surface of the first separator which has passed through the transfer roller.

As the adhesive flows in the coating groove of the discharge roller, the adhesive layer having the first width is continuously applied on the top surface of the first separator.

A glue application roller for use in a gluing assembly equipped with at least one scooping roller includes a glue roller body that is provided with a central hole to receive a drive shaft. The glue roller body has at least two parts including a base and an outer ring. The base is operatively connected to the drive shaft by a non-positive fit. The outer ring is configured with at least one cavity. The base and the outer ring are coupled to each other non-positively via at least one first means. On at least one side of the glue roller body, there are second means that ensure that compressed air and/or another gaseous or liquid medium is fed into or discharged from the cavity so as to effectuate a change in a circumferential contour of the cavity.

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 method and apparatus are presented. A first roller has a sensor that senses a speed of the workpiece while the workpiece is in contact with the first roller and moving relative to the first roller causing the first roller to rotate. The sensor senses the speed of the workpiece from a rotation of the first roller. A second roller causes the sealant on the second roller to be applied to a surface of the workpiece when the workpiece is in contact with the second roller and moving relative to the second roller. The second roller is rotationally linked to the first roller. A third roller causes the sealant on the surface of the workpiece to spread on the surface when the workpiece is in contact with the third roller and moving relative to the third roller. The third roller is rotationally linked to the second roller.

A coating machine has a receiving box, a releasing device, a length measuring device, a driving roller device and a coating device. The releasing device, the length measuring device, the driving roller device, and the coating device are assembled inside the receiving box. The coating device has a coating pole and a releasing set. The coating pole is arranged below the releasing set. The releasing set has a receptacle to contain an activator. The receptacle has at least one releasing hole to release the activator. The coating machine adopts the coating device with a simplified structure and has a merit of coating the activator evenly.
