Abstract
The present invention refers to hoses for irrigation by dripping and the like and to the manufacturing processes for the same. Thin plastic film produces a hose which in a single unit lies flat while empty, and oval or round when water under pressure enters along the same. The characteristics of primary conduction derivation or draining, pressure reduction and exit by dripping and the like result from the simple act of sealing a plastic film while imprinting enclosure circuits of various shape on overlapped edge sections of the hose.
Claims1
The method of manufacturing irrigation hoses for dripping and the like comprising forming a primary flow duct from a thin plastic film having overlapped layers and passing a smooth roller with at least one groove defined therein over said overlapped layer of plastic film, said smooth roller portion sealing the overlapped layer of plastic and forming said primary flows duct while said at least one groove forming a secondary unsealed, fluid passage therebetween leading from said primary flow duct to an exit position at the edge of said overlapped layers.
