Abstract: An apparatus for monitoring deposition of a liquid-to-pasty medium on a substrate has a sensor fitted with two electrodes and an electronic circuit connected to the sensor for generating a signal which is characteristic of the substrate and the medium. The electronic circuit measures the imaginary component of the electrical permittivity of the substrate moving, together with the medium, between the two electrodes, and uses the measured value to determine the characteristic signal.

Abstract: The invention relates to apparatus monitoring the deposition of a liquid-to-pasty medium on a substrate and comprising at least one sensor fitted with two electrodes which are configured at a given, slight distance from the substrate surface and which apply an AC voltage to the substrate and medium, the substrate moving relative to the sensor, further comprising a test electronics connected to the sensor and emitting a signal which is characteristic of the substrate together with the medium.

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.
