Abstract: An air wipe device to direct linearly displaced opposing jet streams of compressed air or pressurized solvent, to incrementally remove adhering particulate matter from a linearly drawn article of indefinite length passing through a central channel. The air wipe is characterized by a plurality of transverse extrusion channels defined by oblique swept baffles, each extrusion channel having mediately positioned opposing jet stream orifices and each channel further communicating and merging with longitudinal exhaust channels coaxial with the central article channel, the exhaust channels terminating in exhaust ports adjacent to, but displaced from, a central wire entrance orifice.
