ABSTRACT:
A hollow tube (3) supports a spring (5) coaxially positioned within the tube (3) and free to rotate within it. The tube (3) has a longitudinal slot (4) through which components (2) threaded onto the coils of the spring (5) hang down. A motor 6 rotates the spring (5) causing the components, constrained by the slot (4), to move longitudinally along the slot (4). When they reach the end of the slot (4), they are orientated by the end of the spring (5), which has been suitably shaped, to the correct orientation to be presented for automatic mounting on a printed circuit board.
