An applicator for coating metal wire with resin, an associated method for coating resin on metal wire, and an installation containing the applicator while using the method. The apparatus that contains an applicator for applying an resin solution and a wiping section, wherein the distance between these two can be adjusted as well as the length of the wiping section. The applicator applies a surplus of resin solution, while the wiping section calibrates this to the desired amount in order to obtain the final amount of dried resin on the wire. Both applicator and wiping section are contained in an encasement with provisions to recuperate evaporated solvent thereby reducing harmful emissions. In the associated method the resin to solvent ratio is used to steer to the final amount.

An apparatus for melting thermoplastic material is disclosed. The apparatus includes a heated manifold and at least one heating element disposed within the heated manifold. The heated manifold defines a plurality of cavities, a pump supply passage, and a discharge passage. The plurality of cavities are spaced apart from one another, and each receives particles of thermoplastic material from a hopper. The particles of thermoplastic material are melted within the plurality of cavities. The pump supply passage receives molten thermoplastic material from the plurality of cavities and supplies the molten thermoplastic material to a pump. The discharge passage receives pressurized molten thermoplastic material from the pump and is in fluid communication with a dispenser. The heating element transfers heat substantially throughout the heated manifold.

An apparatus for melting and dispensing thermoplastic material is provided that includes an un-heated hopper having an inlet for receiving particles of a thermoplastic material and an outlet for discharging the particles and a heated manifold including at least one cavity formed therein and having an inlet and an outlet the inlet communicating with the outlet of the hopper for receipt of the particles from the hopper. The hopper is disposed external of the heated manifold. The heated manifold is effective for melting the particles into molten thermoplastic material therein. The apparatus further includes a pump having an inlet in fluid communication with the cavity. An outlet of the pump is in fluid communication with an inlet of a dispenser and an outlet of the dispenser is effective for dispensing the molten thermoplastic material therethrough.

A monitoring apparatus is provided to monitor an amount of a liquid discharged from a nozzle. The monitoring apparatus includes a discharge case. The discharge case is configured to receive liquid discharged from a nozzle. The discharge case includes a storage space for storing the liquid. A photographing unit photographs the level of the liquid stored in the storage space.

Disclosed is a coating apparatus configured to properly detect a liquid surface of a coating liquid stored within a slit nozzle. The disclosed coating apparatus includes a slit nozzle, a moving mechanism, a storage portion illumination unit, and an imaging unit. The slit nozzle includes an elongated main body, a storage portion configured to store a coating liquid within the main body, and a slit-shaped ejecting port configured to eject the coating liquid fed from the storage portion through a slit-shaped flow path, wherein at least a part of each of a first wall and a second wall which face each other in the main body is formed of a transparent member. The moving mechanism is configured to move the slit nozzle with respect to a substrate. The storage portion illumination unit is configured to illuminate an inside of the storage portion through the transparent member of the first wall. The imaging unit is configured to image the inside of the storage portion through the transparent member of the second wall.

Systems and methods related to dispensing fluid and controlling a dispensing operation. The system includes a fluid dispenser including an inlet and an outlet, the dispenser being operable to start and stop the flow of the fluid from the outlet onto a substrate. The system also includes a fluid supply reservoir adapted to hold the fluid, and having an outlet coupled in fluid communication with the inlet of the fluid dispenser to establish a flow path for the fluid between the fluid supply reservoir and the outlet of the fluid dispenser. The fluid supply reservoir further includes a pneumatic input coupled to an air flow path adapted to receive pressurized air for forcing the fluid from the outlet of the reservoir. An electronic air flow meter device is operatively coupled to the air flow path to produce electrical output signals.

A method for checking the security of installation of a joining element to be fixed to a component via an adhesive connection, wherein the adhesive is taken from an adhesive receptacle and is curable by exposure to light from a light emitter. The fill level of the adhesive receptacle is monitored and, upon reaching a lower threshold value of the determined level of the adhesive receptacle, a fluid connection device of a second adhesive receptacle having an adhesive fill level which is higher than that of the adhesive receptacle, is actuated to produce a fluid connection having an adhesive output device. The intensity of the light emitted from the light emitter is inspected by at least one sensor and a signal is output upon falling short of a threshold value of the light received by the sensor.

Provided is an application device for applying and spreading an application liquid to and on a predetermined application area of a target surface, which is capable of smearing the application liquid on the application area. The application device (D) includes a brush unit (4) having a brush bristle bundle (41a), and performs a step of causing, while moving a nozzle orifice (32a) of a dispenser (3) along at least a portion of the surface of a rivet (S11) and an area of a wall (Sp) surrounding the base of the rivet (S1), a sealing liquid to be ejected from the nozzle orifice (32a) and to adhere to the portion, and thereafter, a step of spreading the adhering sealing liquid by causing the brush bristle bundle (41a) to slide on the surface of the rivet (S1) and the area of wall (Sp) surrounding the base of the rivet (S1).
