FIELD: manufacture of flexible tubes. SUBSTANCE: flexible tubing has fluoroplastic tube, metal ends, and reinforcing braid which is pre-braided closed sheath molded in internal surface of fluoroplastic tube. For manufacturing fluoroplastic tube, pre-braided closed sheath is axially fed together with guide rod from longitudinal space of drift in the course of extrusion. This enables shaping flow section of tube in molding slot with reinforcing member molded in it. Device for manufacturing fluoroplastic tube has barrel, piston, and drift with longitudinal space. Device is provided with movable guide rod for housing internal member in the form of pre-braided closed sheath. Guide rod has arbitrary sectional area and is positioned equidistantly in respect to extensions of barrel and drift. EFFECT: improved stability of sectional area shape of flexible tubing. 3 cl, 4 dwg
