Abstract
An irrigation hose (10) includes a continuous strip member (27). The continuous strip member (27) is formed by extruding a substrate (20) and allowing the substrate (20) to cool. Then a flow path (25) is extruded on the substrate (20). The continuous strip member (27) is then operatively connected to the inner wall 10a of the irrigation hose (10).
Claims12
A method of making an irrigation hose, comprising:
- a) extruding a substrate at a first temperature, and allowing the substrate to cool to a second temperature;
- b) extruding a bead of material on the substrate;
- c) forming a flow path from the bead of material extruded on the substrate, having a plurality of emitter units, on the substrate, thereby operatively connecting the flow path to the substrate to form a continuous strip member;
- d) extruding a hose having an inner wall;
- and
- e) operatively connecting the continuous strip member to the inner wall.

A method of making an irrigation hose, comprising:
- a) extruding a substrate at a first temperature, and allowing the substrate to cool to a second temperature, the second temperature less than 160° F., the substrate has a top surface and a bottom surface, the substrate having a thickness of from 0.002 inches to 0.020 inches;
- b) extruding a bead of material on the substrate;
- c) forming a flow path from the bead of material extruded on the substrate, having a plurality of emitter units, on the top surface of the substrate to form a continuous strip member;
- d) extruding a hose having an inner wall;
- and
- e) operatively connecting the continuous strip member to the inner wall.
