International ClassB05B 015/00AbstractTurbulent-flow emitter channel sections are vacuum-formed in an extruded flat plastic strip. The strip is then applied to a hose substrate, and inlet and outlet openings are formed at opposite ends of the channel sections. The strip may be hot-melt bonded to the substrate during a co-extrusion process, or it may be applied to the hose substrate in a separate operation. Flow rates are easily controlled without changing the structure of the strip by varying the number of channel sections in which outlet openings are formed. | |
