An apparatus (10) for packaging articles straddles a conveyor line delivering articles to be packaged. In one embodiment, the apparatus includes an article holding unit (40) moveable linearly between a retracted position wherein it is positioned to one side of the conveyor line (14) and an operative position wherein it is positioned downstream of the conveyor line so that it receives and holds an article (22) arriving at the apparatus. A bag transfer unit (42) is also moveable linearly between a first position to one side of the conveyor line opposite that of the article holding unit (40), to retrieve the bag (212) in which the article is to be placed and a second position to pull the bag over at least a portion of the article holding unit and the article held thereby. As the bag transfer unit draws a bag over the article and the article holding unit, the article holding unit is moved to its retracted position allowing the bagged article to fall to another conveyor line (16) and be carried away from the apparatus. In another embodiment, the article holding unit and bag transfer unit are incorporated into a single article bagging assembly (400). The assembly is moveable along a linear slide (404) to one side of the conveyor line to retrieve a bag and to position the assembly to receive the article to be packaged. Once the article is received by the assembly and the bag has been retrieved, the article is pushed into the bag and the bagged article is released allowing it to fall to the conveyor line and be carried away from the apparatus.
