Abstract RU 2007654 C1

FIELD: ventilation systems. SUBSTANCE: reinforcing member and band with overlapping edges are spirally wound on mandrel. Band is coated with polymeric material on the width of its overlapping edges. Reinforcing member to be wound is placed on the edge of the last coil on mandrel, and covered with the edge of next coil. Edges are joined by high-frequency welding and hose is removed by applying force to projection formed by reinforcing member. EFFECT: improved functional and operating characteristics. 10 cl, 10 dwg
