An adhesive applicator includes an actuation axle, a first hub unit, a second hub unit, a plurality of elastic members, and a pliable dispenser web. The first and second hub units are mounted on the actuation axle to be spaced apart from each other, and to rotate with the actuation axle about a rotation axis. Each of the elastic members is disposed between the first and second hub units, and has a radial elastic force relative to the rotation axis. The pliable dispenser web is configured to wrap around the elastic members, and can be deformed in compliance with a topology of an attachment region of a shoe component against the radial elastic force.

An optical device coating assembly is provided. The optical device coating assembly includes a substrate support operable to retain an optical device substrate. The coating assembly further includes a first actuator connected to the substrate support. The first actuator is configured to rotate the substrate support. The coating assembly includes a holder configured to hold a coating applicator against an edge of the optical device substrate when the optical device substrate is rotated on the substrate support and a second actuator operable to apply a force on the holder in a direction towards the substrate support. The second actuator is a constant force actuator.

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.

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 including a transfer roller and an applicator roller, the transfer roller having an engraved pattern on its surface that corresponds to the pattern of adhesive to be applied to the tipping paper web, the applicator roller being 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, where the engraved pattern includes individual adhesive containing cells to break up adhesive that coats the engraved region of the transfer roller.

Adhesive sheet material application squeegees are disclosed.

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.

An applicator, for applying a glutinous substance to a seam between a first part and a second part, comprises a roller, comprising a circumferential surface, and a housing, comprising a delivery port, a scraper, and a shaper. The roller is coupled to the housing and is rotatable relative to the housing about an axis. The circumferential surface of the roller is communicatively coupled with the delivery port. The intersection of the circumferential surface and a virtual plane, passing through the axis, is a non-linear segment. The scraper is geometrically complementary at least with the non-linear segment. The shaper is communicatively coupled with the scraper.

An adhesive applicator includes an actuation axle, a first hub unit, a second hub unit, a plurality of elastic members, and a pliable dispenser web. The first and second hub units are mounted on the actuation axle to be spaced apart from each other, and to rotate with the actuation axle about a rotation axis. Each of the elastic members is disposed between the first and second hub units, and has a radial elastic force relative to the rotation axis. The pliable dispenser web is configured to wrap around the elastic members, and can be deformed in compliance with a topology of an attachment region of a shoe component against the radial elastic force.

A coating apparatus, which coats only the outer circumferential edge face of a workpiece with film-forming liquid, even if the workpiece is a non-circular thin lens or the like, a rotating mechanism is configured so that a workpiece and an imitating form having the same shape as the outer shape of the workpiece can rotate synchronously around the same rotation axis center, a coating mechanism includes a pressing roller that can rotate with the imitating form while being pressed against an outer circumferential edge face of the imitating form, and a coating part including a coating roller which, while being pressed against the outer circumferential edge face of the workpiece, rotates with the workpiece and applies the film forming liquid to the outer circumferential edge face of the workpiece, a rotary transmission unit that synchronously rotates the pressing roller and the coating roller having the same outer shape.

An applicator (200), for applying a glutinous substance (140) to a seam (330) between a first part (310) and a second part (320), comprises a roller (210), comprising a circumferential surface (216), and a housing (220), comprising a delivery port (222), a scraper (232), and a shaper (234).
