Abstract
A drip irrigation hose formed of an elongated flat sheet of flexible water impervious material having two longitudinally extending ribs attached to a surface of the material and positioned adjacent to one edge thereof, the ribs being die-formed to be precisely dimensioned and precisely spaced from one another and to be serrated on the inner sides thereof. The sheet is turned over on itself to form a lapped longitudinal seam between opposing longitudinal margins of the sheet, and the ribs are heat sealed, or otherwise attached to the other surface of the sheet and extend between the opposing margins to form a flow regulating tube, with the serrated sides of the ribs creating turbulence in the water flowing in the flow regulating tube. The hose has filter-type inlets longitudinally spaced along the flow regulating tube and outlets from the flow regulating tube longitudinally displaced from the respective inlets.
