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.

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.

An apparatus is disclosed for applying a strip of sealant to a web of roofing shingle stock as the web moves along a processing path. The apparatus includes an applicator wheel disposed on one side of the processing path and having a peripheral surface. The applicator wheel is rotatably mounted and oriented such that rotation of the applicator wheel moves the peripheral surface of the applicator wheel toward, adjacent to, and then away from the moving web of shingle stock. A nozzle preferably in the form of a slot die is disposed adjacent to the peripheral surface of the applicator wheel. A source of sealant is supplied and a delivery system is configured to deliver the sealant from the source of the sealant to the slot die under a predetermined pressure. The slot die and delivery system are configured to project a stream of sealant toward and onto the peripheral surface of the applicator wheel at a predetermined speed. This applies a coating of sealant to the peripheral surface of the applicator wheel. The moving web of roofing shingle stock engages the sealant on the peripheral surface of the applicator wheel as the peripheral surface moves adjacent to the web. This, in turn, draws sealant from the peripheral surface of the applicator and onto the web of roofing shingle stock thereby applying the strip of sealant to the web.

The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.

A substrate treating apparatus comprises a container comprising a reservoir and a roller rotatably mounted relative to the container. A portion of an outer periphery of the roller is positioned in the reservoir. The outer periphery comprises a first groove comprising a width greater than at least twice a depth of the first groove. Additionally, methods of treating a substrate with the substrate treating apparatus are disclosed.

The present disclosure is directed, in part, to a method of applying a flowable substance to a substrate. The method comprises contacting a portion of the substrate with a portion of a rotating applicator as the substrate is conveyed, and immersing the portion of the rotating applicator in the flowable substance to accumulate the flowable substance on the portion of the rotating applicator. The method further comprises engaging a metering device with the portion of the rotating applicator, metering a portion of the accumulated flowable substance on the portion of the rotating applicator off of the portion of the rotating applicator using the metering device, and applying a portion of the remaining flowable substance on the portion of the rotating applicator to the portion of the substrate when the portion of the substrate contacts the portion of the rotating applicator.

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.

An adhesive transfer system for applying a pattern of adhesive to a web of tipping paper as it is being fed through a smoking article filter assembly unit is disclosed. It comprises a transfer roller and an applicator roller. The transfer roller has an engraved pattern on its surface that corresponds to the pattern of adhesive to be applied to the tipping paper web. The applicator roller is nipped with the transfer roller so that adhesive received on its surface is transferred from said engraved region onto the applicator roller as the transfer roller and applicator roller rotate to form an adhesive pattern on the applicator roller for subsequent transfer onto a moving web of tipping paper in contact with said applicator roller. The engraved pattern comprises individual adhesive containing cells to break up adhesive that coats the engraved region of the transfer roller.
