  • Patent number: 4754867
    Abstract: A printed circuit (PC) board feed apparatus includes a feed roller arrangement adapted to receive sequentially delivered PC boards and to position the PC boards in lateral edge engaging contact with a pair of aligned, linear support rails. The opposed lateral edges of each of the PC boards are directed by a respective pivoting idler/guide roller into a guide slot in each of the parallel support rails. Once positioned in the spaced, facing guide slots, the PC boards are sequentially engaged and displaced by a pair of pneumatically actuated roller/drive belt assemblies positioned adjacent to the guide slots. A pneumatic cylinder displaces a first plurality of engaging rollers in each roller/drive belt assembly in a timed manner toward and away from an adjacent respective drive roller/belt combination so as to sequentially position each of the PC boards in contact with the pair of roller/drive belt assemblies for sequentially displacing the edge-to-edge arranged PC boards in a stepwise manner.
