Claim Text:
1. 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 module having a manifold chamber for receiving the liquid from the pressurized source; a channel body having a plurality of grooves in fluid communication with the manifold module, the grooves defining liquid channels whereby liquid from the manifold chamber passes through the liquid channels and is directed towards the target substrate as the liquid streams; a channel body cover covering a portion of each of the grooves in the channel body, wherein a first segment of each liquid channel being created by the portion of the grooves in the channel body enclosed by the channel body cover, the first segment being an enclosed tunnel in fluid communication with the manifold chamber in the manifold module; wherein a second segment of each liquid channel being created by a portion of the grooves in the channel body, the second segment being in direct fluid communication with the first segment, having an open-face flume configuration, and having a liquid discharge end projecting toward the target substrate; wherein the liquid stream leaves the apparatus in a completely open, unconfined state as it approaches the textile substrate, wherein an impingement stream is directed to the liquid stream at a point when the liquid stream is located in the open, unconfined state after leaving the apparatus; wherein the length of the second segment is at least four (4) times greater than the largest cross-sectional diameter of the second segment and static pressure dissipation occurs therein; a plurality of impingement jet directional passages, each impingement jet directional passage being associated with a corresponding liquid channel, each impingement jet directional passage further having: a liquid collection module adapted to capture the liquid stream during the diverted flow path.
