A device for applying adhesive to a substrate, having an application roller that is rotatable about an axis, an installation for dispensing adhesive to a circumferential area of the application roller, a dispensing region of the application roller for dispensing adhesive from the application roller, and having a doctor blade, wherein the dispensing region for adhesive in the rotation direction of the application roller is located behind the installation for dispensing the adhesive to the application roller and ahead of the doctor blade. In such a device it is provided that the application roller is rotatable about a vertical axis and the excess adhesive wiped by the doctor blade reaches a collection installation that is located below the doctor blade. In a method for applying adhesive to a substrate, excess adhesive that has not been applied to the substrate is disposed of.

A coating film transfer tool has a head part in order to provide a coating film transfer tool that is capable of reducing operation failure of an internal mechanism such as a rotation transmission mechanism, and improving feeling of use. The head part is provided with a transfer roller for transferring a coating film layer of a transfer tape T to a transferred surface by abutting on a back side of the transfer tape T. In addition, the head part is provided with a debris removal roller for removing debris of the coating film layer of the transfer tape T adhering to the transfer roller. The debris removal roller is disposed at a rear of the transfer roller and is arranged in close proximity to or in contact with the transfer roller.

When a coating material is rolled between rolls to generate a a coating film, and the coating film is transferred onto the coating object, at first, a residual coating material layer based on a residual coating material is formed on each of the surfaces of the rolls, and supply of the coating material and transfer of the coating film are carried out in a state where the residual coating material layer is retained on each of the surfaces of the rolls, thereby suppressing abrasions between the rolls and the coating material.

The present invention is method for forming a sandwich structure having a pattern of particulate material enveloped between a carrier material and a cover material. The method allows accurate forming of pre-determined pattern at high production speed. Such a method is particularly useful in the manufacture of disposable absorbent articles, such as baby diapers.

According to an embodiment, provided are a coating device, a meniscus head, and a coating method capable of obtaining a uniform coating film with a large area. A coating device according to an embodiment forms a coating film by a meniscus method, the coating device comprising: a member that conveys a base material; a coating bar; a slot die that supplies a coating liquid to a surface of the coating bar; and a member that supplies the coating liquid to the slot die, in which each of the members is disposed such that the coating liquid supplied from the slot die is supplied to a space between the coating bar and the base material via the surface of the coating bar to form a meniscus.

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.

According to one embodiment, a coating apparatus includes a coating bar configured to face a member to be coated, and a plurality of nozzles configured to supply a liquid toward the coating bar. A number of the nozzles is 3 or more. An arithmetic mean roughness Ra of at least a part of a surface of the coating bar is not less than 0.5 m and not more than 10 m.
