Introduction
Hans Hardegger is a notable inventor based in Greifensee, Switzerland. He has made significant contributions to the field of coating technology, holding 2 patents that showcase his innovative approach to enhancing manufacturing processes.
Latest Patents
One of his latest patents is an "Apparatus for stripping a boundary air layer from a traveling web." This invention involves a web that is coated as it travels over a deflecting roll and beneath a slot nozzle, from which a curtain of coating material falls. A suction box, open toward the roll and web, extends the full axial length of the roll and has upstream and downstream ends. The upstream seal is juxtaposed with the web and extends the full axial length of the roll, while a similar downstream seal is provided on the downstream side. Air is withdrawn from the box between the seals to suctionally strip a boundary layer of air from the web.
Another significant patent is the "Edge-control system for curtain coater." This coating system features a slot nozzle that allows a curtain of coating material to fall on a traveling web. It includes a pair of guide elements that flank the slot nozzle, with inner faces that engage and define the edges of the curtain. Aspiration elements fixed at the lower ends of the guide elements are designed to aspirate excess coating material from the curtain through vacuum passages.
