Abstract
A drip irrigation hose is formed from an elongated flat strip of flexible material. One side edge portion of the strip is deformed to form a series of indented channel formations deformed out of the plane of the strip, and the strip is then folded with the deformed side edge portion outermost and the channel formations facing inwardly and overlapping the underlying opposite side edge portion of the strip. The opposite side edge portions are sealed together to form a main conduit within the strip and a series of secondary conduits along the channel formations. Each channel formation has a series of spaced inlet channels extending transversely across the innermost side edge of the strip and into the secondary conduit.
