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 μm and not more than 10 μm.

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 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.

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.

According to one embodiment, a coating head includes a coating bar, nozzles, a first member, second members, third members, elastic members, and a position controller. The coating bar faces a coating member. The nozzles supply a liquid toward the coating bar. The first member includes first recesses. A portion of the nozzles is between the first recesses and the third members. The portion of the nozzles and the third members are fixed to the first member by the second members. The elastic members are located in at least first, second, or third positions. The first position is between the third members and the second members. The second position is between the portion of the first recesses and the nozzles. The third position is between the portion of the nozzles and the third members. The position controller controls a relative position between the coating bar and the nozzles.

According to one embodiment of the invention, a coating apparatus includes a first pipe, a first pump, a first nozzle, a second nozzle, and a holder. The first pipe includes a first inflow port, a first outflow port, and a second outflow port. The first pump is configured to supply liquid toward the first inflow port. The first nozzle includes a first nozzle inflow port and a first nozzle discharge port. The first nozzle inflow port is connected to the first outflow port. The first nozzle discharge port is configured to discharge the liquid passing through the first pipe. The second nozzle includes a second nozzle inflow port and a second discharge port. The second nozzle inflow port is connected to the second outflow port. The second nozzle discharge port is configured to discharge the liquid passing through the first pipe. The holder holds the first nozzle and the second nozzle. The holder is configured to form a first state and a second state. In the first state, a height of the first nozzle discharge port and a height of the second nozzle discharge port are not less than a height of the first pipe. In the second state, the height of the first nozzle discharge port and the height of the second nozzle discharge port are lower than the height of the first pipe.

According to one embodiment of the invention, a coating apparatus includes a coating bar, a plurality of nozzles, a plurality of holding portions, and a detector. The coating bar is configured to face a coating target member. The plurality of nozzles are configured to supply a liquid toward the coating bar. One of the plurality of holding portions holds one of the plurality of nozzles. The one of the plurality of holding portions is configured to control a position of the one of the plurality of nozzles relative to the coating bar. The detector is configured to detect a quantity corresponding to respective positions of the plurality of nozzles with respect to the coating bar.

According to an embodiment, a coating apparatus includes an application head, a first moving device, a second moving device, a feeding device, and a suction device. The application head is opposed to a coating surface of a target with a predetermined distance, and forms a meniscus pillar of a coating material between the application head and the coating surface. The first moving device moves the application head. The second moving device moves the application head. The feeding device feeds the coating material between the application head and the coating surface of the target. The suction device sucks the coating material. A distance between the application head and the coating surface is made greater than the predetermined distance, and the coating material is sucked from the meniscus pillar by the suction device.
