Abstract:
A substrate processing apparatus comprising a substrate holding rotating mechanism, a process liquid supply mechanism having a nozzle for dispensing a process liquid toward a principal face of the substrate, a processing liquid reservoir for holding sufficient process liquid to form a liquid film covering the whole principal face of the substrate, a liquid film forming unit for forming the liquid film by supplying the process liquid onto the principal face of the substrate in a single burst, and a control unit for controlling the liquid film forming unit and the process liquid supply mechanism such that the process liquid is dispensed from the process liquid nozzle toward the principal face of the substrate after formation of the liquid film covering the whole area of the principal face of the substrate by the liquid film forming unit.
Abstract:
An electro-mechanical system for the collection and recovery of materials inside thin-film deposition facilities, comprising multiple elements able to intercept the wasted particles of material during a coating process. These elements are disposed in individual modules (1, 5), possibly combined in multiple configurations according to the shape of the deposition chamber; swivel, depending on the material to be recovered, thanks to a power unit (4), a transmission system (6, 10, 15a, 15b), an electronic interface (9) to automate the rotation of the elements. These elements can be palettes (3) placed vertically in each of the modules (1, 5), made of a composite material, characterized by a core of metallic material or alumina and by two surface polymeric layers with low adhesion to the selected core and therefore easily removable, but at the same time resistant to the temperature and pressure conditions inside the deposition is chamber.
Abstract:
A method for dispensing a foamed material onto a substrate surface, including: generating a relative movement between the substrate surface to be coated and an exit opening of a material dispensing apparatus, mixing at least two material components in a mixing device to provide a free-flowing, foamable dispensing material, generating a pressure differential between the mixing device and the dispensing region located downstream in the direction of flow from a discharge cross-section of the exit opening, conveying the dispensing material from the mixing device for the dispensing material to the exit opening, and discharging the dispensing material from the exit opening onto the substrate surface. The dispensing material be kept under such a pressure in the region adjacent to and upstream from the discharge cross-section of the exit opening that the dispensing material in this region has a foaming rate that is less than 10% of the foaming rate which ensues at the end of the foaming process.
Abstract:
A device for applying a two-part adhesive to a substrate includes a carrier, a first pump, a second pump, at least one manifold and at least one applicator. The first pump and the second pump are mounted on the carrier and each pump has an inlet and an outlet. The first pump pumps a first part of the two-part adhesive from its inlet to its outlet, and the second pump pumps a second part of the two-part adhesive from its inlet to its outlet. The at least one applicator is configured to mix the first part with the second part to form the two-part adhesive that is discharged from the outlet of the at least one applicator onto the substrate.
Abstract:
A dispenser system employs a packaging module for use with moisture sensitive materials. The packaging module comprises an outer carton and an inner bladder, which is substantially impermeable to moisture and is filled with one part of an adhesive. The carton is loaded on a mobile cart and the one part adhesive is supplied to a pump/mixer without exposure to moisture in the atmosphere. The packaging and dispensing system can be used in conjunction with mechanized adhesive application equipment for the construction trades.
Abstract:
A method of making an article having a substrate and two materials applied thereto includes providing a metered fluid dispensing system having first and second supply sources for supplying first and second fluids, respectively, an output device having at least one dispensing nozzle, and at least two pumps for pumping the first and second fluids from their respective supply sources to the at least one dispensing nozzle, the pumps being in close proximity to the dispensing nozzle. The dispensing system is configured to selectively control the passage of the first and second fluids from each one of the at least two pumps to the at least one dispensing nozzle. The substrate is conveyed past the fluid dispensing system in a machine direction and the first, or second, or first and second fluids are applied to the substrate in a plurality of segments, each segment having a volume per unit length and applied in a length in the machine direction to define a pattern, and in which wherein the pattern includes at least some areas in which the first or second fluid is present without the other fluid.
Abstract:
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.
Abstract:
Apparatus for producing material by a chemical reaction between a first chemical reagent and a second chemical reagent. The apparatus comprises a chemical mixing arrangement; a dispensing chamber; a dispensing piston configured to dispense reacting mixture from the dispensing chamber; and a control unit for controlling the movement of the dispensing piston and for controlling operation of the chemical mixing arrangement.The chemical mixing arrangement has a mixing chamber and injection apparatus configured to produce a jet of a first chemical reagent and a jet of a second chemical reagent such that the jets collide within the mixing chamber to produce reacting mixture. The dispensing chamber has an inlet for receiving the reacting mixture from the mixing chamber and an outlet for dispensing the reacting mixture.The control unit is arranged to co-ordinate movement of the dispensing piston with the operation of the chemical mixing arrangement such that the chemical mixing arrangement is caused to mix the chemical reagents while the dispensing piston is caused to move at a controlled rate.
Abstract:
A system for manufacturing a trim panel includes a plurality of rollers for routing a foam core of the trim panel along a path. A first doctor blade for applying an adhesive resin is disposed adjacent to the first side of the foam core. A second doctor blade for applying an adhesive resin to the second side of the foam core is disposed adjacent the second side of the foam core. The system further includes a mixing head having an output port. A mixing tube is attached to the output port. The mixing head defines first, second, and third distinct fluid paths for the first, second and third components, respectively. The first, second, and third fluid ports extend to the output port. In use, the system continuously monitors the actual application rate of the adhesive resin and compares this actual application rate to a desired application rate and adjusts the pump output accordingly.
Abstract:
The invention relates to a dispensing process particularly for a sealing/adhesive product which comprises at least one step of pumping the sealing/adhesive product to allow a step of distribution thereof onto at least one part to be sealed, such as for example a motor vehicle mechanical component; an intermediate step of deaeration of the sealing/adhesive product, so as to optimize its distribution on the part to be sealed, is provided between the pumping step and the distribution step. The apparatus for dispensing the sealing/adhesive product (14) comprises elements (2) for feeding the sealing/adhesive product to elements (4) for distributing it onto at least one part (5) to be sealed and sealing/adhesive product deaeration means (3) which cooperate with the pumping and distribution elements for the uniform deposition of the sealant/adhesive on the part.
