A hose is made by continuously transporting a first strip of plastic film through an assembly station. One or more contiguous molten beads are deposited onto a central region of the film. The beads are formed into a flow regulating passage defined by side walls. A second strip of plastic film, which is narrower than the first strip of film, is sealed to the side walls while molten to form a flow regulating passage between the sidewalls and the first and second strips of film. Inlets to the flow regulating passage and outlets from the flow regulating passage are formed at spaced intervals along the hose. The first strip of film is longitudinally folded to overlap the margins and the overlapping margins are sealed to complete the hose.
