The lengths of the links comply with the conditions: A͞C=b and C͞B=a, where a and b are the semiaxes of ellipse p-p. Slider 1 moves along fixed guides t-t whose axis coincides with axis 0x. Slider 1 is connected by turning pair A to link 3 which is connected by turning pairs C and E to sliders 2 and 4. Slider 4 moves along fixed guides m-m whose axis is perpendicular to axis 0x. Link 5, turning about fixed axis 0, is connected by sliding pairs to sliders 2 and 6. Slider 7 moves along fixed guides q-q whose axis is perpendicular to axis 0x. Cross-piece Bd of slider 7 moves In cross-shaped slider 5 which has guides perpendicular to each other. Link 9 is connected by turning pair C to slider 2 and moves in slider 8. When slider 1 moves along guides t-t, point C of slider 2 describes ellipse p-p and point D of slider 8 describes versiera s-s of this ellipse. The equation of the versiera is 4b²x+xy²=8ab².
