Link 8 is connected by turning pairs E and F to follower 7 and to link 5 which turns about fixed axis C. Link 3 is connected by turning pairs D and M to follower 2 and to roller 4. Springs 11 and 12 hold rollers 10 and 9 against cams 6 and 1. Motion is transmitted from cam 1 to roller 4 on whose axis the suction cup is mounted.
