FIELD: production of hollow body. SUBSTANCE: mixture with a considerable content of thermoplastic particles is melted into a paste-like bar, is placed in looped layers in a hollow form on one another, is shaped into a hollow body with subsequent reinforcement by cooling, and is removed. Rotating around its axis, the paste-like bar is delivered concentrically from the end side into a hollow mold provided with a molding mandrel. The paste-like bar is successively placed over the perimeter in the space of the inner wall formed by a gap, said delivery continuing until the inner wall and the molding mandrel become wetted all over with the component parts of the paste-like bar. EFFECT: higher efficiency. 4 cl, 8 dwg
