Link 5 rotates about fixed axis x-x and is connected by screw pair E to link 4. Link 1 is connected by turning pairs B and D to links 4 and 2. Link 2 turns about fixed axis F. Link 3 slides in guide p of link 4 and has slot a along which pin A of link 1 slides. When link 5 is rotated, link 4 is traversed along axis x-x. The motion of link 4 is transmitted to links 1 and 2 and to link 3 carrying tool b. The shape of the curve described by nose f of tool b is varied by adjusting pivot D of link 1 along the axis of link 2.
