A mechanism suitable for picking up and positioning small parts is described. This mechanism increments adhesive tape 1 from a supply roll 2 to a takeup roll 3 operatively carried by a housing 4. The housing at surface 5 is adapted to be connected to an actuator, such as a robot arm (not shown), for vertical and lateral movement. The adhesive tape, which may be similar to conventional masking tape, has its coated side facing a small part 6 that is to be picked up from a conveyor belt or the like. Roll 2 is splined to the same shaft 7 as a ratchet disk 8 that is held against undesired backward rotation by a spring-loaded detent 9. Similarly, roll 3 is splined to the same shaft 10 as a ratchet disk 11 that is held against undesired backward rotation by a spring-loaded detent 12.
