An apparatus for intermittently applying a liquid from a pressurized source onto a target substrate in the form of liquid streams, the apparatus comprising: a manifold chamber for receiving the liquid from the pressurized source; a channel component having a plurality of liquid channels in fluid communication with the manifold chambe each liquid channel having a liquid discharge end projecting towards the target substrate whereby the liquid from the manifold chamber passes through the liquid channels creating the liquid streams directed toward the substrate each channel component further having a landing disposed adjacent to the liquid discharge ends of the liquid channels the landing having a plurality of impingement jet positioning apertures extending there through, each impingement jet positioning aperture being associated with a particular liquid channel and having a central axis oriented in an intersecting relation to the central axis of the corresponding liquid channel; an impingement jet module having a plurality of impingement jet gas tubes mounted in an impingement jet body with tube distal ends extending therefrom, each impingement jet gas tube having a jet tube opening, wherein each impingement jet gas tube is aligned with an associated impingement jet positioning aperture and wherein the tube distal ends of the impingement jet gas tubes further being inserted into the corresponding impingement jet positioning apertures whereby an impingement stream passing through the impingement gas jet tube towards an associated liquid stream will create a diverted flow path in the associated liquid stream and a liquid collection module adapted to capture the liquid streams in the diverted flow paths, and characterized in that the jet tube openings of the impingement jet gas tubes are substantially planar with the surface of the landing nearest to the location of the liquid stream. a manifold chamber for receiving the liquid from the pressurized source; a channel component having a plurality of liquid channels in fluid communication with the manifold chambe each liquid channel having a liquid discharge end projecting towards the target substrate whereby the liquid from the manifold chamber passes through the liquid channels creating the liquid streams directed toward the substrate each channel component further having a landing disposed adjacent to the liquid discharge ends of the liquid channels the landing having a plurality of impingement jet positioning apertures extending there through, each impingement jet positioning aperture being associated with a particular liquid channel and having a central axis oriented in an intersecting relation to the central axis of the corresponding liquid channel; an impingement jet module having a plurality of impingement jet gas tubes mounted in an impingement jet body with tube distal ends extending therefrom, each impingement jet gas tube having a jet tube opening, wherein each impingement jet gas tube is aligned with an associated impingement jet positioning aperture and wherein the tube distal ends of the impingement jet gas tubes further being inserted into the corresponding impingement jet positioning apertures whereby an impingement stream passing through the impingement gas jet tube towards an associated liquid stream will create a diverted flow path in the associated liquid stream and a liquid collection module adapted to capture the liquid streams in the diverted flow paths, and characterized in that the jet tube openings of the impingement jet gas tubes are substantially planar with the surface of the landing nearest to the location of the liquid stream.
