FIELD: manufacture of articles from composite polymer materials by winding method. SUBSTANCE: envelope 1 of mandrel is formed by longitudinal sectors; central shaft 8 of mandrel is hollow and stepped. Sectors are mounted on shaft with the aid of keys 10 made in form of dovetail; keys 10 are mounted on bearing shoes 11 made in form of prisms. Number of faces of prisms corresponds to number of sectors of envelope 11. Stages 12 of shaft 8 are made in descending line of varying diameter and shoes till they rest against next stage. Since each shoe is mounted above other shoe and its diameter is lesser than axial diameter of hole of article, there is no difficulty in disassembly of mandrel inside ready article at drawing shaft 8 towards larger axial hole. EFFECT: enhanced reliability. 2 cl, 2 dwg
