In one aspect, methods of making a carbon coating are described herein. In some implementations, a method of making a carbon coating comprises applying a first adhesive material to a substrate surface to provide an adhesive surface; rolling a carbon source over the adhesive surface to provide a carbon layer on the adhesive surface; and rolling an adhesive roller over the carbon layer to remove some but not all of the carbon of the carbon layer to provide the carbon coating.

An apparatus for dispensing a brushable substance comprises a bracket and a sleeve, comprising an inner tubular sleeve wall and an outer tubular sleeve wall. The sleeve is coupled to the bracket and is rotatable relative to the bracket. The apparatus also comprises a cartridge, comprising an inner tubular cartridge wall and an outer tubular cartridge wall. The apparatus additionally comprises a valve, configured to be communicatively coupled with the cartridge, a brush-arm assembly, coupled to the sleeve a linear actuator to control flow of the brushable substance from the valve, an annular plunger, positioned between the inner tubular cartridge wall and the outer tubular cartridge wall, and a twist-lock pressure cap, configured to be hermetically coupled with the cartridge. The cartridge is configured to be positioned between the inner tubular sleeve wall and the outer tubular sleeve wall and between the twist-lock pressure cap and the valve.

A coating device includes a coating member, a nip forming member, a pair of conveying members, and circuitry. The nip forming member forms a coating nip together with the coating member. The pair of conveying members is opposed each other to nip and convey a recording medium to the coating nip. The circuitry is configured to cause the pair of conveying members to release nipping of the recording medium at timing when a leading end of the recording medium reaches the coating nip.

A device for a lacquer transfer includes a transfer roller mounted at and rotatable relative to a frame. The roller includes a cylindrical support-body, first ring-element, second ring-element, and a tire including a middle-section forming a circumferential outer contact surface with depressions, the roller configured to roll with the outer contract surface on a work surface of a workpiece for transferring lacquer from the outer contact surface and the depressions to the work surface. The tire includes two annular end-sections attached to a cylindrical outer shell of the support-body resulting in two axially separated and circumferentially extending connections, the tire, connections, and outer shell of the support-body being fluid-tight. The first and second ring-elements are in the first cavity seated on the support-body at a distance in an axial direction of the roller from one another and the middle-section of the tire between the first and second ring-elements is prestrained in the axial direction.

A device and a system for a lacquer transfer with a frame, transfer roller with a circumferential lateral wall, a drive unit, a slit nozzle, the slit nozzle at least indirectly connected to the frame, an outside contact surface of the lateral wall including depressions, the transfer roller mounted rotatably about an axis of rotation at the frame, the drive unit configured to drive the transfer roller for the transfer roller to rotate about the axis of rotation. The slit nozzle includes a supply connection, nozzle-cavity, slit-shaped nozzle-channel and at least one limiter, the supply connection coupled to the nozzle-cavity for supplying lacquer to the nozzle-cavity, the nozzle-channel extending from the nozzle-cavity to a muzzle end formed by the slit nozzle at the end of the nozzle-channel for dispensing lacquer, the slit nozzle configured by the limiter to adjust a cross-section in a restriction area of the nozzle-channel.

A gluing device of an end edge of a log including an introduction assembly into the gluing device of a log, a handling assembly for a log associated to detection device of the end edge and including a pair of rolls for advancement and holding in rotation of the log, a glue dispensing assembly and a transfer assembly of the log including a transfer plane positioned downstream of the lower handling roller. The glue dispensing assembly is placed in series between the lower handling roll and the transfer plane and includes a transverse tank for the glue, housing cyclically movable glue transfer members. The transverse tank is provided with an upper cover provided with a plurality of openings provided in succession side by side at a set distance along a transverse row. The movable glue transfer members include a plurality of tips provided in succession along a transverse row, alternatively projecting through the relevant openings and retracted within the transverse tank because of the cyclical movement.

A fluid application device for mechanical fasteners such as rivets, screws, bolts, and similar fasteners, and a robot end effector including such a device as well as a robot being equipped therewith. The fluid application device includes a fluid application element having a curved application surface, wherein the curved application surface includes a channel configured to receive a fluid. A brush is arranged at the curved application surface such that the fluid is able to wet the brush elements. The device further includes a gripping device configured to push a mechanical fastener against the wetted brush elements.
