Carrier 1 rotates about fixed axis A and is connected by turning pair D to planet gear 9 which meshes with fixed internal sun gear 2. Planet gear 9 is connected by turning pair B to sliding link 3. Link 3 is connected by turning pair C to saw blade 4 and by sliding pair E to slider 8 which moves along slot a of link 3. Slider 8 turns about axis E of link 5 which is connected by turning pair F to link 6. Link 6 is connected by turning pair G to link 7 whose end H slides in slot b of saw blade 4. The pitch radius of gear 2 is twice that of gear 9. As a result, point B, lying on the pitch circle of gear 9, travels in a straight line along axis x-x passing through point A. When carrier 1 rotates, saw blade 4 reciprocates parallel to axis x-x. The saw blade is fed downward, along axis y-y, by turning link 5 about axis A.
