  • Patent number: 5363966
    Abstract: A plastic bag bundle comprised of a plurality of juxtaposed flat plastic bags each having a front and rear wall panel and a mouth opening for inserting one or more articles in the bag. A flat article(s), such as coupons, cards, packets, etc., is retained captive in one of the front and rear panels. The bundle is formed of bags having the flat article in some of said bags disposed offset from said article in others of said bags. The bags with the offset articles are interposed in a predetermined sequence with the other bags so as to form a bundle having a generally constant thickness in the area of the juxtaposed panels. Such bag bundles are used in bagging machines where articles are dropped in a first of this bundle of bags which is opened, and wherein the bundle is usually held on wicker pins disposed next to a loading station.

  • Patent number: 5290391
    Abstract: An apparatus and a method for attaching articles to a plastic bag wall and particularly for attaching flat articles, such as coupons, cards, packets, samples, etc., to an inside wall of a panel of the bag and at different locations thereon. The articles are attached by feeding a bag-forming film sheet of plastic material to an article insertion station where the plastic sheet passes about a nip roll. An article transfer mechanism transfers articles from a discharge end of one or more supply magazines to two or more support surfaces at an article insertion station. These support surfaces are aligned with distinct sections of the bag-forming film sheet. An attaching film sheet is fed over a support roll which is in frictional rotational contact with the nip roll with the attaching film sheet aligned over the distinct sections of the bag-forming film sheet.
