Abstract: The invention relates, inter alia, to a device for applying a plurality of threads of a fluid, such as adhesive or lotion, to a moving web-like substrate, having a plurality of outlet openings for the threads of fluid, wherein each outlet opening is disposed between a pair of flow openings, through which a flow fluid, in particular compressed air, flows in order to achieve thread oscillation. The special feature consists, inter alia, in that the outlet openings are disposed along a curved path.

Abstract: An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a centre line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with centre line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.

Abstract: An electronic control circuit, for use in connection a hot melt adhesive dispensing system having a relatively large applicator head, has a plurality of heater circuits and a plurality of temperature sensors disposed upon different regions of the relatively large applicator head, wherein the electronic control circuitry can effectively interface between the plurality of heater circuits and the plurality of temperature sensors, and the adhesive supply unit (ASU) hose and head connector, so as to control individual ones of the plurality of heater circuits and thereby ensure that all of the heater circuits will maintain the same temperature setting throughout all regions of the applicator head.

Abstract: A mechanism for the application of viscous substances, particularly of dispersion adhesives, onto a moving substrate, includes a jet body, upon which a variety of application modules are aligned, which are supplied with substances by means of at least one supply unit, and a slot jet configuration, with which the substance can be applied to the moving substrate in the form of a defined application pattern. The slot jet configuration may be exchanged for the purpose of altering the application pattern. The slot jet configuration is formed by a jet strip system, which is useable for any application pattern, and a distribution plate, which is replaceable regardless of application pattern and which is upstream of the jet strip system in terms of flow.

Abstract: An apparatus for feeding a fluid comprises a deposition head having a main surface, spaced feed ducts arranged on the main surface along a length of the deposition head for feeding the fluid and a channel formed on the main surface and extending at least along entirely the length of the deposition head. The apparatus further comprises a spacer plate slidably supported by the channel so that the spacer plate can be fastened to the main surface at any position along the entire length of the channel. A deposition module is mounted on the spacer plate and has a nozzle in communication with at least one of the feed ducts for depositing the fluid. The apparatus advantageously facilitates reposition of the nozzle with minimal effort.

Abstract: A device for dispensing flowing media, in particular hot-melt adhesives, cold adhesive, lubricants, paints or the like, in a metered manner, comprises a deposition head having numerous flowing-media feed ducts opening to a boundary surface thereof, and at least one deposition module mounted on the boundary surface and comprising a nozzle head to deposit the flowing media in a particular pattern, such as spots, beads or the like, on a moving substrate. The device comprises at least two mounting pins projecting from the boundary surface and passing through and beyond boreholes of the deposition module. At least one clamping element acting, at least indirectly, on the deposition module is provided in end zones of the mounting pins which project from the deposition module. Affixation or exchange of the deposition module is thus significantly simplified by slipping the deposition module onto the mounting pins and fastening the clamping element.
