ABSTRACT:
A gas wiping nozzle for a wire coating apparatus includes an inlet portion defining a converging inlet passage for a coated wire that is axially drawn through the gas wiping nozzle. A wiping portion is further included and defines a wiping passage for the coated wire, downstream and in an axial extension of the inlet passage. The wiping portion has a gas outlet surrounding the wiping passage for blowing wiping gas onto the coated wire. A protruding annular lip is arranged between the converging inlet passage and the wiping passage, and the annular lip defining a passage for the coated wire that is narrower than the wiping passage so that the gas outlet means in the wiping passage is protected by the protruding annular lip against direct contact with the coated wire which is axially drawn through the passages of the wiping gas.
