Abstract
A pellet-shaped article marking system marks two sides of a pellet-shaped article. A hopper is disposed over a ramp-type conveyor and feeds pellet-shaped articles onto the conveyor. A first marking device marks a first side of the pellet-shaped articles. A pickup drum receives the pellet-shaped articles from the conveyor and transports them to a second marking device so that a non-marked side of the articles faces the second marking device. The second marking device marks the non-marked side of the articles. The pickup drum then discharges the pellet-shaped articles into a bin.
