Abstract
Abstract Apparatus for drying or removing adhering substances from the surface of a continuous advancing strand or other substantially non-adsorptive material moving at high speeds which enables the wire to be ink-printed immediately. The air wiper utilizes a compressed-air source to dry the wire, as well as a single vacuum pump for exhaust. Cone deflectors direct the wet air away from the wire and toward the vacuum chamber drainage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
Apparatus for drying or removing adhering substances from the surface of a continuous strand or other substantially non-adsorptive material which is being advanced along its longitudinal axis comprising: (a) at least one or more pressurized air assemblies applying compressed air against and away from a strand and the strand's direction of travel; (b) in a high velocity vacuum suction chamber at least one or more cone deflectors located in the path of the pressurized air and surrounding the strand; (c) means to supply compress air to the air assemblies, and (d) pressurized air passing along the external surface of the cone with means to draw and exhaust wet air and moisture away from the deflector to a drainage.
Claim 2
Dependent Claim
