Wearing down of a doctor blade by a filler contained in a coating solution is prevented. The doctor blade is for scraping off the coating solution, containing the filler, from a circumferential surface of a coating roller, the coating roller being for applying the coating solution to a battery member being conveyed. A surface of the doctor blade is made from an ultra-high molecular weight polyethylene.

An apparatus is used for coating a web of material or a sheet of material with a hot-melt adhesive (14). In order to simplify the application of hot-melt adhesive to webs of material or sheets of material, it is provided that the apparatus (10; 110) has a heated surface (25; 124) and a supply roller (16) with hot-melt adhesive (14) movable perpendicular to its axis of rotation, the web of material or the sheet of material being movable relative to the supply roller (16) while in contact with the heated surface, a pressure apparatus, which presses the supply roller (16) against the heated surface (25: 124), and a drive apparatus being provided, which drive apparatus causes the supply roller (16) to roll on the web of material or the sheet of material.

A gluing station for applying glue to product elements guided in a product stream is intended to permit continuation of the production process and gluing of the product elements in a particularly simple and reliable manner even after a temporary machine stop or production standstill. For this purpose, according to the invention, a moistening system is assigned to a glue application roller that can roll on the product stream. During operation of the gluing station, in the event of a stopped product stream, the glue application roller is pivoted away from the product stream and the transfer roller for the duration of the standstill and is kept rotating, whereby the surface of the glue application roller is moistened.

Disclosed is a gravure coating apparatus including: two frames; a first support shaft which is installed between the two frames; a rotary spline which is installed between the two frames and in parallel with the first support shaft; and multiple gravure roller modules which are installed to be fitted with the first support shaft and the rotary spline; in which the multiple gravure roller modules receive rotational force from the rotary spline and move independently along the first support shaft.

A coating apparatus is connectable to both an image forming apparatus and a sheet feeder. The coating apparatus includes a coater, a carry-in entrance, and an ejector. The coater coats a recording medium with a treatment liquid. The carry-in entrance is on one of two exterior wall surfaces facing each other. The recording medium is conveyed from the sheet feeder through the carry-in entrance. The ejector is on another of the two exterior wall surfaces. The ejector ejects the recording medium to the image forming apparatus. A position of the carry-in entrance on the one of the exterior wall surfaces matches a position of the ejector on said another of the exterior wall surfaces.

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.

A wearable system for dispensing a substance is disclosed. The wearable system includes a base element, at least one reservoir surface defining a reservoir disposed in the base element, at least one first opening disposed along on an outward facing portion of the base element and providing fluid communication with the reservoir, and a rolling element disposed in the at least one first opening such that a first portion of the rolling element is outside the base element and a second portion of the rolling element is inside the base element.

The present disclosure is a sheet producing device for producing a multi-layer sheet by applying a coating material to a sheet material. The sheet producing device includes a radiation light source that emits radiation light, a division part that divides the radiation light into measurement light to be incident on the multi-layer sheet and reference light with which a reference surface is to be irradiated, and an optical member that emits the measurement light onto the multi-layer sheet and receives the measurement light reflected by the multi-layer sheet. An interference detector that detects interference light between the measurement light reflected by the multi-layer sheet and the reference light reflected by the reference surface, and a thickness calculator that calculates a thickness of the sheet material and a thickness of the coating material of the multi-layer sheet based on the detected interference light are further included. As a result, the tact time from the production of the multi-layer sheet to the calculation of the thickness can be shortened.
