FIELD: technological processes.
SUBSTANCE: blank is drawn through opening of working tool of drawing machine. Linearity and lower twisting of profile, and also preset weight of running meter and face size are provided since blank elements are pressed with creation of partial stresses along perimeter. Conditions are created for alignment of draws along profile elements due to redistribution of metal volume into free zones.
EFFECT: higher accuracy of geometrical parameters of profile of elevator guide rails.
