Application of coverage product on a surface using a print head that is mounted on a robot arm, and that is made up of a body equipped with at least one printing nozzle. A method includes a) defining a strip of surface to be coated, b) defining a trajectory for the strip of surface, c) removing a strip of surface from an information sheet modelling the surface to be coated, d) restarting at a) until the modelled surface to be coated becomes a null area, e) defining an activation program for each print head nozzle on each trajectory, and f) applying the coverage product by activating each print head nozzle on the different trajectories depending on the orientation of the print head at each remarkable point, based on the activation program.

Provided is a coating apparatus where a coated object W is moved relative to an application nozzle 10 located above the coated object, and a coating liquid P is applied to a surface of the coated object via a slit-shaped discharge port 12 at a distal end of the application nozzle. In a coating liquid reservoir 11 storing the coating liquid therein, a coating liquid feeder 14 formed with a coating liquid holding recess 14a in a predetermined pattern shape is rotatably disposed at place above the slit-shaped discharge port. A partition member 13 for dividing the slit-shaped discharge port into plural discharge parts 12a along the longitudinal direction of the slit-shaped discharge port is disposed in the slit-shaped discharge port. The coating liquid feeder 14 is rotated to apply the coating liquid to the surface of the coated object via the discharge parts at places corresponding to the coating liquid holding recess.

A valve arrangement for applying flowable medium to a substrate, having a main valve body with a medium channel for flowable media which is able to be closed by a movable closure member and to which a nozzle part having a nozzle opening of the valve arrangement is connected, wherein the valve arrangement has a pivotable lever movable out of a fastening position and into a releasing position, wherein the pivotable lever, during the movement from the fastening position into the releasing position, exerts a detaching force on the nozzle part in order to support the detachment of the nozzle part from the main valve body. In a first phase of its movement out of the fastening position and into the releasing position, the lever is movable in a straight line and exerts the detaching force on a push-off surface of the nozzle part, and entrains the nozzle part.

An adhesive dispenser having a pump and a slotted nozzle assembly is disclosed. The pump includes a pump body assembly having a nozzle body defining a recess that extends into the body, and a fluid channel with an inlet to receive adhesive and an outlet open to the recess. The pump includes a valve member movably disposed in the fluid channel and configured to selectively block the adhesive from flowing to the outlet. The slotted nozzle assembly includes a baffle plate having a slot that extends through the plate and a cover plate attached to the plate. The slotted nozzle assembly is received in the recess of the nozzle body, such that an input channel extending from the outlet of the body to the slot is defined between the baffle plate and the nozzle body, and an output channel extending from the slot to a dispensing outlet is defined between the baffle plate and the cover plate.

The present invention relates to electrode slurry coating apparatus and method, the present invention ultimately allowing the process efficiency to be increased and rate of errors to be reduced when double-layer structured active material layers are formed by temporally adjusting the height of first and second discharge outlets through which active material is discharged.

The disclosure relates to a print head for applying a coating agent to a component, in particular for applying a paint to a motor vehicle body component, having a nozzle plate, a nozzle in the nozzle plate for dispensing the coating agent, and a valve element movable relative to the nozzle plate for controlling the release of coating agent through the nozzle, the movable valve element closing the nozzle in a closed position, whereas the movable valve element releases the nozzle in an opened position, and having a seal for sealing the nozzle with respect to the movable valve element in the closed position of the valve element. The disclosure provides that the seal is not designed as an elastomer insert on the valve element.

The disclosure concerns a printhead for applying a coating agent to a component, in particular for applying a paint to a motor vehicle body component, having at least one outlet opening for dispensing the coating agent, a coating agent supply for supplying the coating agent to the outlet opening, a movable valve element, the valve element in the closed position closes the outlet opening, whereas the valve element in the open position opens the outlet opening, and with a valve actuator for moving the valve element between the opening position and the closed position. The disclosure additionally provides for a flexible membrane which separates the valve actuator from the coating agent supply, the actuator side of the membrane facing the valve actuator and the coating agent side of the membrane being exposed to the coating agent in the coating agent supply.

Embodiments of the disclosed subject matter provide a micronozzle array including a linear array having a plurality of depositors connected in series, where a first depositor of the plurality of depositors may border a second depositor on a least one side boundary. The micronozzle array may include plurality of orifice arrays, where a width of each orifice in the plurality of orifice arrays is 20 μm or less in a minor axis of its cross section to flow, to regulate flow through a delivery gas distribution channel. The micronozzle array may include a plurality of exhaust distribution channels, where the delivery gas distribution channel and at least one of the plurality of exhaust distribution channels have separate fluid communication with each of the plurality of depositors.

The present invention relates to an applicator device for applying cleaning, sanitizing and/or disinfecting liquid or gel across an external surface of an elongate, three-dimensional object or cover therefor.

The disclosure relates to an application device, preferably for alternately applying a 2C material, comprising a first component material and a second component material, on the one hand and the first component material on the other hand, in particular onto a motor vehicle component, comprising preferably an application head and a first line section leading to an application nozzle, wherein the first line section comprises a mixer and a first line for a first component material and a second line for a second component material, wherein the first line and the second line are connected to the mixer and the mixer mixes the first component material and the second component material with each other for forming a 2C material. The application device is characterized in particular in that it comprises a second line section for the first component material to form an application bead of alternately the 2C material from the first line section and the first component material from the second line section.
