Beschreibung
Zusammenfassung:	polymeric tube production. SUBSTANCE: tube includes framework of band with openings. Band is helically coiled and in zones of its turns engagement band edges are mutually joined. Framework is placed in monolithic polymer. Each opening of band is closed by means of arc-shaped bridge overlapped on two edges of opening. Method for making reinforced polymeric tube comprises steps of punching through openings in band, coiling band to helix, joining edges of band and forming polymeric envelope. Each opening is formed by double cut-trough and subsequent bending of formed bridge. EFFECT: improved loading capacity of tube. 3 cl, 7 dwg
