Abstract: Apparatus is described for facilitating the filling and sealing of bags for shipping or mailing. The bag supply preferably is in web or strip form, i.e. the bags are joined along successive closed sides of the bags to form a continuous web with the bag bottoms along one edge and the unsealed bag top ends along the other edge of the web. Means are provided to advance the web one bag length each cycle to a cutting station which severs the bag from the web. A vacuum picker and pusher bar convey the separated bag from the cutting station to a carrier comprised of a series of continuously moving chains having lugs between which the bags are first inserted and then retained for travel with the chains. The pusher bar and the spacing between the lugs cooperate to maintain the unsealed end of the bag open sufficiently to receive an article inserted while the bag is moved by the carrier. At the end of the carrier run, sealing means close the open end of the bag. The entire operation is controlled by a motor driven cam programmer and indexed by a photocell arrangement which detects indexing marks imprinted on the bags.
