FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of screw spirals. Billet is twisted from sheet material around longitudinal axis. Assembly of sheet material is formed from an odd number of adjacent layers of elastic elements, which form rhombus in cross section, with holes on ends for rotation in opposite sides around longitudinal axis of assembly and fixation of twisted assembly on rigid shaft.
EFFECT: as a result, auger manufacturing technology is simplified.
