THIS PAPER DISCUSSES COMBINING CONSTANT SPEED AND INDEXING MOTION IN THE SAME CONTINUOUS LENGTH OF CONVEYOR CHAIN. THESE MOTIONS ARE GENERATED BY PRECISION MECHANICAL DRIVES. TWO VERY DIFFERENT DRIVES ARE EXAMINED IN THIS PAPER. THE COMBINED LINEAR AND ROTARY DRIVE IS ACTIVE AND CAN BE THE DRIVE FOR THE ENTIRE CONVEYOR SYSTEM. THE COMPOUND CAM DEVICE DESCRIBED IS PASSIVE AND IS POWERED BY THE MOVEMENT OF THE EXISTING CHAIN SYSTEM.
