Abstract

The device has two mutually parallel slats extending crosswise to the running direction of the wire, namely an approach slat and a departure slat which with a wire guide surface each touch the revolving wire. Contained between the two slats is a blowing slot connected to a compressed air supply. Forming between the approach slat and the wire is a wedge-shaped gore tapering in the wire running direction, into which gore empties a water spray system. The departure slat has a step type clearance at the point where the wire leaves the wire guide surface.
