A manifold that allows for increased flow performance, at a reduced pressure, and a flow path that is easily maintained, and fluid dispensing systems that allow for the precise, controlled spacing of beads of multiple component adhesives, and other liquids, and allow for multiple beads to be dispensed onto a substrate simultaneously are disclosed. A control portion for a manifold that solves the disadvantages relating to scaling an open channel and a carrier that provides a mechanism for applying an adhesive and/or a two-part adhesive easier are disclosed.

A device for applying adhesive and/or sealant having a housing for receiving a container, said housing having the following: a receiving chamber for receiving the container; a closable application tip which is connected to the receiving chamber and through which the adhesive and/or sealant can be discharged; a stable casing for the receiving chamber; at least one region of the housing which is in the form of a deformable pressure region and which allows pressure to be exerted from the outside onto the container which can be placed in the receiving chamber.

A coating applicator that applies a coating or liquid to a variety of different substrates having different contoured surfaces is disclosed. A coating applicator of the present disclosure is able to reach, contact, and cover the entirety of a contoured substrate. In this manner, the coating applicator is able to transfer a coating to the entirety of the contoured substrate. Additionally, fluid application systems of the present disclosure include systems for advantageously providing a fluid to a fluid applicator.

This invention relates to an adhesive deposition tool for applying a bead of structural adhesive onto an application surface of a wind turbine blade component. The tool comprises a top portion defining an upper boundary of an open-ended chamber, two side portions defining side boundaries of the chamber and a supply channel for supplying adhesive to the chamber. The chamber comprises a front end and a rear end, the rear end being the end from which adhesive is deposited onto the surface when the tool is moved along the surface, wherein the top portion and/or at least one side portion is configured such that the height and/or the width of the chamber decreases towards the front end of the chamber.

A system for finishing surfaces with a finishing material includes a handle assembly with proximal and distal ends. A material reservoir is mounted on the handle distal and includes an inlet and an outlet. A material applicator tool is mounted on the reservoir and receives material from the reservoir outlet. A discharge mechanism includes an extendable-retractable component or linear actuator connected to the reservoir for discharging or reloading material. Multiple embodiments utilizing different linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism. Additional embodiments include an adjustment mechanism on the push-to-open valve mechanism accommodating adjustment of flow of finishing compound when the push-to-open valve is engaged.

Devices, systems, and methods of improving paste flow during the manufacture of wind turbine blades are provided. An apparatus for applying adhesive to a composite structure (e.g. wind turbine blade) comprises a paste shoe having a top surface with an aperture to receive a supply of adhesive, and two legs extending downwardly from the top surface and configured to engage a surface of the composite structure to define an interior volume within the paste shoe. A transport mechanism (e.g. wheels, treads) are disposed on each leg to move the paste shoe relative to the composite structure while adhesive is dispensed within the interior volume. A force applicator, applies a force to the paste shoe to maintain a constant interior volume and thus a uniform bead of paste is applied to the composite structure.

Provided is an application tool that allows reduction of an amount of waste by using no masking sheets, and can easily form a coated portion such as an antislip protrusion with reduced variation in a short time period. The application tool includes a support plate and a plurality of application bodies disposed at the support plate so as to protrude with height positions of the tips aligned with each other. A tip recess is disposed at the tip portion of each of the plurality of the application bodies as a holding recess for holding coating liquid.

A chemical solution supply apparatus (1) includes a container (10) and a chemical solution supply implement (20) that, in a state of being connected to a mouth portion (14), can switch over a state where the container (10) is sealed and a state where a chemical solution in a storage portion (12) is allowed to be supplied to the outside of the container (10). The chemical solution supply implement (20) has a base (30) and a supply body (50). The base (30) has a retaining portion (40), a pressing portion (42), and a restricting portion (34) that restricts displacement of the supply body (50) with coming into contact with the supply body (50) when the supply body (50) is pressed against pressing force of the pressing portion (42). The supply body (50) moves away from the retaining portion (40) to thereby form a supply flow passage, and comes into contact with the retaining portion (40) to thereby block the supply flow passage.

Systems and methods for dispensing a viscous fluid using an apparatus that may include: a housing; an applicator coupling on the housing that can releasably couple an applicator that contains a viscous fluid; a gas supply coupling that receives a pressurized gas from a gas supply; a valve having a first open position in which the valve can be gradually and controllably opened to adjustably control the delivery of pressurized gas to the applicator coupling, and a second closed position where the pressurized gas delivered to the applicator coupling is vented; and a valve actuator configured to permit a user to gradually and controllably open the valve to controllably dispense the viscous fluid from the applicator, where ceasing to depress the valve actuator vents the applicator coupling and immediately discontinues the dispensing of viscous fluid from the applicator.

An adapter is configured to be mounted onto or otherwise coupled to a hot-melt adhesive dispenser. The adapter may include a body defining at least a first inlet channel, a second inlet channel, and a feed channel. The first inlet channel is configured to receive a first adhesive. The second inlet channel is configured to receive a second adhesive. The feed channel is configured to direct at least one of the first adhesive or the second adhesive to the hot-melt adhesive dispenser.
