Abstract

1,143,606. Irrigation pipes. INDUSTRIELE ONDERNEMING WAVIN N.V. 13 Sept., 1966, No. 40951/66 Heading A1B. Drainage or irrigation pipes are formed by extruding a plastic tube 1, forming a slit 2 in the pipe in a longitudinal direction, unfolding the material to form a flat band and rolling up the band. When the material is unwound it reforms itself into tubular form. Parts of the edges 3, 4 are forced out of the plane of the edges to form closing means by closing the pipe.
