An apparatus for the intermittent application of a liquid to pasty medium onto an application surface, comprising an application valve which can be switched between an open and a closed state and is intended for dispensing the medium onto the application surface, a volumetric delivery pump for metering a volume of the medium to be passed on to the application valve, and a drive for operating the volumetric delivery pump is, inter alia, described and illustrated. The characteristic feature consists in that the apparatus has an electronic controller which, in each case cyclically, activates the drive and the application valve in dependence on each other.

A suck-back type coating gun unit characterized in that a needle, which is formed into a single body with a movable valve body of a valve mechanism, is provided, and a cam-type valve driving mechanism, which includes a cam that is at its cam surface in contact with the tip end of the needle, is provided. In this suck-back type coating gun unit, a cam-type valve driving mechanism that makes stroke motions is configured in which the rotational operation of the cam body is converted into a stroke operation to make a valve ON and OFF operation of the hot melt coating gun unit, so that the ON operation is made by the ridge portion of the cam body and the OFF operation is made by the valley portion of the cam body.

A fluid application device includes an applicator head, a first fluid passageway extending in the applicator head, a second fluid passageway extending in the applicator head, a plurality of metering devices connected to the applicator head. A first metering device of the plurality of metering devices is configured to meter a fluid to the first fluid passageway and a second metering device of the plurality of metering devices is configured to meter the fluid to the second fluid passageway. The device further includes a plurality of valve modules, each valve module actuatable between an open condition and a closed condition to control flow of the fluid and a nozzle having one or more discharge orifices. At least one orifice of the one or more discharge orifices is positioned downstream from the first passageway and the second passageway to receive the material from both the first and second fluid passageways.

A composite friction unit of a three dimensional composite body is formed in a system for continuous process manufacturing of composite friction units. The system uses a plurality of rolls of reinforcing fiber fabrics, a resin dispensing system that receives a panel of reinforcing fiber fabric from each one of the rolls and separately dispenses resin through a plurality of dispensing tubes, each associated with a different panel, onto a surface of each panel. A forming die is positioned to receive the plurality of panels of reinforcing fiber fabric after resin is dispensed onto the panels and is configured to form a composite panel from the plurality of panels of reinforcing fiber fabrics. A cutting mechanism cuts a desired shape part from the composite panel.

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 p.m 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 invention relates to a method for 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. The method includes a) defining a strip of surface to be coated, b) defining a trajectory for the strip of surface, the trajectory including a succession of reference points, 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 reference point, based on the activation program.

An application device for coating components with a coating agent includes: a print head having several individual nozzles for discharging the coating agent; and a nozzle valve attached to each individual nozzle, each nozzle valve being openable for a valve opening time to discharge the coating agent from the respective nozzle. Each nozzle valve is assigned in each case a nozzle valve supply line, which nozzle valve supply line, at an outlet opening thereof, supplies the coating agent to the respective nozzle valve. Each nozzle valve supply line has an inlet opening to be closed or shut off such that a quantity of the coating agent that is metered in a defined manner or a volume of the coating agent that is metered in a defined manner is receivable in a closed off manner within the nozzle valve supply line.
