A method and devices for dispensing adhesive onto an elastic strand are configured to apply first, second, and third volumes of adhesive onto first, second, and third portions of the elastic strand, respectively. When the elastic strand is adhesively secured to a substrate to form a personal disposable hygiene product, the first and third portions of the elastic strand define opposing ends of the elastic strand, which are adhered with a larger amount of adhesive or a stronger adhesive material capable of limiting movement of the strand at the opposing ends. The method and devices advantageously use a module and nozzle which maintain separation between first and second adhesive streams received from different adhesive supplies at least until flow within the nozzle. This arrangement enables use of different adhesives to form the first, second, and third volumes, as well as wet-on-wet contact dispensing using multiple nozzle outlets.


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 cartridge suitable for use in a bond testing machine, the cartridge comprising: a plurality of a different test tool assemblies; a Geneva mechanism, each of the plurality of different test tool assemblies mounted to the Geneva mechanism and angularly spaced from one another; and a drive unit, coupled to the Geneva mechanism, the drive unit configured to rotate the Geneva mechanism to move each of the plurality of different test tool assemblies to and from a use position. The cartridge preferably includes an improved Geneva mechanism that locks the test tools in their desired rotational positions. The cartridge also preferably includes a mounting plate for the test tools that has identical test tool connection areas so that any test tool can be connected to any tool connection area. Providing a plurality of test tools that can be selectively moved to a use position within a single cartridge allows an operator to change tools without having to demount and remount different test tool cartridges when a different test tool is required. This improves the ease of operation and saves the operator time. Novel methods for use of the cartridge are also described.


Systems and methods for applying liquid coating materials to a substrate, such as an electronic component or circuit board. A control system (18, 24, 26) of a coating system (10) controls an applicator (16) and a robot (14) moving the applicator (16) to apply the liquid coating material to the substrate (12) in accordance with the information contained in a coating program. The control system (18, 24, 26) determines a volume of liquid coating material actually dispensed onto the substrate (12) during the coating program, and compares the dispensed volume to a desired dispensed volume of liquid coating material to produce an error signal representing the difference between the calculated and desired volume values. The control system (18, 24, 26) uses the error signal to change the dispensed volume of liquid coating material on a subsequent substrate by a future coating program.


An adhesive melter and a method for operating the adhesive melter enables predictive maintenance of an exhaust air filter used to remove pressurized air flow that delivers solid adhesive particulate from a fill system into the melter. To this end, the fill system repeatedly actuates to refill a receiving space, and a controller monitors a duration of each fill system cycle. When changes in a calculated average duration of a plurality of fill system cycles exceed a maintenance threshold, an alert is emitted at a user interface to prompt maintenance or replacement of the exhaust air filter before a complete shutdown of the fill system is caused by clogging of the exhaust air filter. Consequently, unplanned downtimes caused by clogged exhaust air filters in the adhesive melter can be minimized, regardless of any variable conditions occurring at the melter.


An apparatus and method for hydrating a particulate biomaterial with a liquid biomaterial includes a vacuum device and a valve for withdrawing a gas from the particulate biomaterial and introducing the liquid biomaterial. The valve includes a hub, a valve body, a particulate port, a vacuum port, and a liquid port. The valve body selectively moves between first and second positions. The valve body at least partially defines a first passage and a second passage. The particulate port, the vacuum port, and the liquid port are each configured to fluidly connect to a particulate container, the vacuum device, and the liquid container, respectively. In the first position, the first passage fluidly connects the vacuum port to the particulate port for withdrawing the gas from the particulate container. In the second position, the second passage fluidly connects the liquid port to the particulate port for hydrating the particulate biomaterial.


An integrated multicomponent dispensing system for use with a fluid dispenser and associated methods of manufacture, such as by 3D printing are provided. The system includes a cartridge including first and second cylinders having first and second chambers for storing first and second fluid components, respectively, and first and second fluid outlets. A static mixer of the system includes a fluid passageway and a plurality of mixing baffles configured to mix the first and second fluid components upon delivery into the fluid passageway. A frangible closure may also be formed integral with the cartridge and/or the static mixer to prevent discharge of the fluid components into the static mixer until this is desired. The formation of the static mixer and optionally also the cartridge as an integral, unitary piece reduces cost of assembly and storage of multiple parts conventionally formed separately.

A feed center (100) for powder coating material includes a hopper (102), an extraction duct, and a control valve. The hopper is connectable in fluid communication with a fluidizing pressure source (138). The extraction duct is connectable in fluid communication with at least one suction source. The a control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and an second position providing an exterior opening in at least one of the control valve and the first extraction duct (128) for exhausting pressurized fluid from the hopper (102) and/or collecting at least some of the air and powder that is exhausted from the powder.
