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.
