  • Patent number: 5106021
    Abstract: An irrigation device, especially suited for trickle or drip irrigation comprises a tubular conduit made by connecting opposite edges of at least two plies of plastics, embossing at least one marginal zone of at least one ply to create a labyrinthine passage for liquid. The two plies may be obtained by lengthwise folding an elongated strip of material.

  • Patent number: 4874132
    Abstract: Drip irrigation apparatus comprising an elongated element of uniform cross section including an extruded closed portion, the extruded closed portion being embossed to define a pressure reducing pathway. A water supply channel may be formed also by extrusion or by sealing of the edges of the elongated element.

  • Patent number: 4413787
    Abstract: Drip irrigation apparatus comprising at least one foil element including at least one first surface having a raised pattern formed thereon and defining a portion of a pressure reducing pathway and at least one second surface joined to the at least one first surface and defining therewith the pressure reducing pathway, the at least one second surface being disposed in non-coextensive overlapping relationship with respect to the at least one first surface thereby leaving at least one water pathway between the interior and exterior of the pressure reducing pathway.

  • Patent number: 4195784
    Abstract: Drip irrigation apparatus comprising first, second and third layers of sheet material, the layers of sheet material being elongate and arranged that both of their side edges lie in confronting and coextensive arrangement, the first, second and third layers being joined to each other at their side edges to define a water supply passage between the first and second layers and to define a water discharge passage between the second and third layers, the second layer being apertured to provide fluid communication between the water supply passage and the water discharge passage. A method and apparatus for producing the drip irrigation apparatus is also provided.

  • Patent number: 4175882
    Abstract: A hose conduit comprises an inner tubular fluid conducting space which is surrounded by a ringshaped space. Openings are provided in the wall of the inner hose leading into the ringshaped space. In the ringshaped space is provided a longway passage extending through repeated bows and bends and repeatedly changing its direction. From the said longway passage openings in the outer wall of the said ringshaped space lead into the open. The assembly of the hose conduit is built up of at least two layers of thin foil which are connected together. The longway passage is obtained by profiling one of the foils, i.e. by applying a raised, embossed pattern to one of the foils.

  • Patent number: 4126998
    Abstract: Irrigation apparatus comprising first and second layers of sheet material, at least one of the first and second layers being configured in relief and the first and second layers being bonded together at touching surfaces such that the bonding of the touching surfaces defines a liquid conduit, at least one pressure reducing path associated therewith and an exit port from each of the at least one pressure reducing paths.

  • Patent number: 4095750
    Abstract: A water conduit of flexible material serves as an irrigation device or as a drainage pipe. At regular or irregular distance from one another cuts are made in the wall of the conduit resulting in tongue like portions which adhere to the wall of the conduit along an uncut portion. These tongues are movable out of the plane of the wall and have an outer surface which is smaller in area than the inner surface thereof.

  • Patent number: 4053109
    Abstract: The present invention relates to an improvement of the irrigation device described in my earlier U.S. Pat. No. 3,887,138.There I have described an elongated continuous hollow hose for conveying fluid through the interior thereof and formed with a helical fluid flow passage of predetermined pitch between the inner and outer surfaces thereof, the helical passage having an axis substantially coaxial with the longitudinal axis of said hose.According to the present improvement the grooving need not be helical, it may be a continuous groove of regular or irregular convolutions, meandering along the extension of the respective hose.
