  • Patent number: 6041575
    Abstract: A method and apparatus for applying an article to the interior surface of a flexible package is provided which includes the application of articles to a flexible web of packaging material at a point along a web feed path which minimizes the likelihood of article separation downstream. Specifically, the present method and apparatus includes a driving system for pulling a web of material through a feed path, a tube former having an inlet positioned along the feed path for receiving the web of material and an article applicator for applying articles onto an interior package surface of the web of material at the inlet of the tube former. In this manner, the article is delivered to the web downstream of the upper edge of the tube former thereby minimizing inadvertent separation of the article from the web as experienced in conventional machines as the web passes over the upper edge of the tube former.

  • Patent number: 6035610
    Abstract: An apparatus for separating individual items from a bandolier of adjacent items have a seam between the items. A pair of upper jaws and a pair of lower jaws open and close horizontally to clamp and release the respective seam. The pair of lower jaws pull the bandolier downwardly through the opened pair of upper jaws. The seam is cut while the pair of upper jaws close to grasp an adjacent seam. The pair of lower jaws open to release the separated item to a delivery system and the pair of lower jaws move upwardly to be adjacent to, and below, the pair of upper jaws. The pair of lower jaws close and the sequence is repeated. At least one sensor identifies an identification feature on the items and transmits signals to a control unit to actuate movement of the pair of upper jaws and the pair of lower jaws. Preferably, a second sensor system assures that separation is only at the respective seams. A method of use is disclosed.
