A spray application system and a method of its operation are provided for applying a spray treatment onto a surface of an airframe of an aircraft. The spray application system includes a set of multiple modular hood units that are combinable to form a combined enclosure that defines a shared interior volume. Each modular hood unit of the set includes one or more enclosure walls. At least two airframe-interfacing edges of each modular hood unit define a portion of a spray treatment region of the airframe. At least one inter-unit-interfacing edge of each modular hood unit is configured to interface with another inter-unit-interfacing edge of a neighboring modular hood unit of the set to form at least a portion of the combined enclosure. A spray access port is defined within an enclosure wall of each modular hood unit.

A spray containment system for a wing-body section includes a forward module, a center module, and an aft module. The forward module has a forward closeout panel configured to engage a forward end of a fuselage center section of the wing-body section. The center module has opposing module side panels each configured to engage a wing lower surface of a wing of the wing-body section. The aft module has an aft closeout panel configured to engage an aft end of the fuselage center section. The forward module and the aft module are independently movable and are configured to be assembled around the wing-body section to define an internal environment that is sealed from an external environment for containing contaminants including at least one of vapors, overspray, and liquids generated during application of one or more of coatings, sealants, and adhesives to localized areas of the wing-body section.

A printing assembly is disclosed for thermal transfer printing onto a surface of a substrate. The assembly comprises at least one first printing system comprising a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of thermoplastic particles is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head, optionally via the rear side of the transfer member, to selected regions of the imaging surface to render particles coating the selected regions tacky, a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to transfer to the substrate the particles that have been rendered tacky to form an adhesive image; and at least one more printing system downstream from the first system.

A pneumatic cleaning gun according to the present invention comprises a gun housing with a compressed air connection, a liquid nozzle with a nozzle cover, and an air intake tube which leads into the covered flow channel and can also be connected to a suction device via a suction hose in order to suction dirt particles through the flow channel. The cleaning gun is configured such that the air intake tube is not rigidly but pivotably mounted on the cleaning gun. The air intake tube can therefore be mounted in a plurality of different positions of use such that the user can find the most comfortable or convenient position of use and the air intake tube can be correspondingly adjusted.

The present disclosure provides a spraying system and a using method thereof. The spraying system includes a lifting apparatus and a spraying apparatus. The spraying apparatus connects to the lifting apparatus and includes a stage, a multi-axis transfer mechanism, a spraying component, a driving component, a surface profile detector, and a controlling component. The multi-axis transfer mechanism is disposed on the stage. The spraying component is disposed on the multi-axis transfer mechanism and the stage. The driving component is disposed on the stage and connects to the lifting apparatus. The surface profile detector is disposed on the stage and scans an area to be sprayed to obtain scanning data. The controlling component is disposed on the stage and controls the lifting apparatus, the spraying component, and the driving component according to the scanning data and pre-stored initial data.

A spray apparatus having built-in air regulation and a swivel connection to an air supply and uses thereof are described herein.

A deposition apparatus that supplies mist to a front surface of an object and deposits a film made of a material substance containing the mist on the front surface of the object, the deposition apparatus comprising a mist supplying section that includes: a mist generating section that generates the mist; an inlet port that introduces the mist generated by the mist generating section into a space; and a supply port that supplies the mist from the space to the front surface of the object, wherein the supply port is provided at a different position than the inlet port in a first direction, in a first prescribed plane that includes the supply port where the first direction and a second direction intersect and that has the mist pass therethrough.
