An apparatus for supplying a liquid medium to a metering unit comprises a housing in which media channels are arranged. One of the media channels is connected to a fluid reservoir that can be acted on by compressed air.

An end effector, for adhesively attaching a first part to a second part, comprises a support and a first nozzle, coupled to the support and movable relative to the support, and a second nozzle, coupled to the support and movable relative to the support. The first nozzle comprises a first-nozzle body, comprising a first-nozzle-body outlet port and a first-nozzle separator plate, extending from the first-nozzle body. The second nozzle comprises a second-nozzle body, comprising a second-nozzle-body inlet port and a second-nozzle separator plate, extending from the second-nozzle body. The end effector further comprises a roller, coupled to the support, rotatable relative to the support about a roller axis, and located between the first nozzle and the second nozzle.

A substrate processing apparatus may include a chamber having a working space, maintaining a vacuum state, and including an upper wall positioned on the working space, a nozzle assembly positioned in the working space, and including nozzles, and a lifting module including a frame positioned outside of the chamber, a lifting part that lifts the frame, and at least one shaft passing through the upper wall, connected to each of the frame and the nozzle assembly, and extending in a direction of gravity.

In manufacturing a laminated iron core by laminating and bonding iron core laminates blanked from a sheet steel strip into a prescribed profile, the adhesive agent can be applied to the iron core laminates in a stable manner without regard to the arrangement and the number of the application spots on each iron core laminate. The metallic die machine (1) is provided with an adhesive agent application unit (12) configured to apply an adhesive agent to a prescribed area of the sheet steel strip (W) corresponding to the iron core laminates (2), and the adhesive agent application unit is provided with a casing (44) defining a plurality of adhesive agent storage chambers (55-57) for storing the adhesive agent before the adhesive agent is applied to the prescribed area. The casing is provided with a plurality of ejection orifices (H1 to H3) each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent.

A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.

A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

Exemplary coating devices and exemplary coating methods for coating components with a coating agent, e.g., for painting motor vehicle body components with a paint, are disclosed. An exemplary coating device comprises an application device that applies the coating agent. The application device may include a paint head that discharges the coating agent out of at least one coating agent nozzle.

A new and improved hot melt adhesive or other thermoplastic material dispensing system comprises two separate and independent rotary gear-type metering pumps with two separate and independent supply sources and fluid supply passageways, or two separate and independent sets of rotary gear-type metering pumps with two separate and independent supply sources and fluid supply passageways, which are able to independently output precisely metered amounts of the hot melt adhesive materials simultaneously onto a particularly substrate through suitable output devices so as to result in a multitude of different hot melt adhesive patterns and at different locations.

Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.

The embodiment provides a coating process capable of simply and inexpensively producing devices having strip-shaped cells, and a coating apparatus usable for the process. The process comprises: (a) placing a bar coating head almost parallel to the substrate, (b) placing plural coating nozzles for supplying coating solution to meniscus-forming parts, so that the center between each adjacent two of the coating nozzles may correspond to the separation area between each adjacent two of the strip-shaped cell bases, and (c) moving the substrate or the bar coating head while the coating solution is being supplied from the nozzles, to form the coating films.
