Gear 7 rotates about fixed axis A and meshes with gear 3 which rotates about fixed axis B. Disk 1 is rigidly attached to (or integral with) gear 7 and is connected by turning pair E to slider 5 which moves along slot a of slotted lever 4. Slotted lever 4 turns about fixed axis D. Gear 3 is connected by turning pair C to link 6. Link 2 is connected by turning pairs K and F to links 4 and 6. When driving gear 7 rotates, link 2, the kneading member of a dough kneading machine, has a complex motion and its point Q describes complex connecting-rod curve q.
