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. The nip roll is moved in the direction towards the support surface to grasp a leading edge of an article positioned on the support surface to position same between the bag-forming film sheet and the attaching film sheet along the distinct sections. The two sheets are then sealed together with the article captive therebetween. The composite film can then be fed to a bag-forming station.
