Latest Patents
One of his latest patents is titled "Inlet for introducing water to wire edge guides for curtain coating." This invention presents an apparatus designed for curtain coating a composite layer formed from multiple coating compositions onto a moving receiving surface. The edge guides consist of two thin, parallel, and closely spaced wires that maintain the horizontal extent of the free-falling curtain. A flushing and lubricating liquid is supplied to the edge guide, and the invention includes a distribution body that delivers this liquid in laminar flow, preventing stationary waves in the curtain that could lead to coating nonuniformities. The design allows for the replacement of the wires without the need for removal or disassembly.
Another notable patent is "Edge removal apparatus including air-flow blocking means for curtain." This invention features an edge blade attached to an edge guide, which intercepts the edge of a falling curtain. The intercepted edge is vacuumed away by a tube positioned near the edge blade, with airflow blocked from the outboard direction. This design directs suction towards the curtain while distributing flushing liquid to encompass the intercepted liquids.
