  • Patent number: 4083451
    Abstract: Each sheet-form layer of plastic film to be superposed with another layer between layers of non-heat conducting material, such as paperboard, is perforated in a pattern such that, when the layers of plastic are superposed between the layers of normally non-heat conducting material for heat sealing, the perforations of each layer of plastic are aligned with imperforated portions of the superposed perforated layer of plastic. When sealing heat and pressure are applied to the superposed layers of plastic and paperboard or the like by conventional heated dies, each layer of plastic is rapidly sealed to the inner surface of both layers of paperboard, or, if initially sealed to the inner surface of one layer, is rapidly sealed directly to the inner surface of the other layer of paperboard.

  • Patent number: 4047358
    Abstract: The articles are enclosed in pockets, formed and sealed in plastic windows, of a foldable paperboard blank which has window openings on opposite sides of a fold line, the blank being covered on one surface by a heat-deformable and heat-sealable plastic sheet, at least over that area having the openings or windows formed therein. A blank support, a molding station and a blank discharge station are arranged along a linear blank travel path at substantially equal spacings from each other. A carrier is oscillatable in a vertical plane including the center line of the travel path, and carries air-released vacuum pick-up means at longitudinal spacings substantially equal to the spacings between the support and the stations. The carrier is oscillated between a first position and a second position. In the first position, a first vacuum pick-up means grips a blank on the support and a second vacuum pick-up means grips a blank, which has already been heated and has pockets formed therein, at the molding station.

  • Patent number: 3946537
    Abstract: An apparatus for forming and closing a display package comprises a card blank and an overlying plastic sheet and includes a carrier for the blank and the overlying plastic which is movable through an operation path. The carrier advantageously comprises a rotatable plate having a plurality of receiving areas for individual cards and plastic sheets which are arranged at spaced annular locations on the table and which may be rotated through the operational path by rotation of the table. Associated with the operational path of movement is a device for feeding either individual cards with window openings or cards which already have plastic sheets affixed thereto onto the associated carrier. The plastic sheets may be fed separately, if desired, so that they will overlie the card blank. A heat sealing and forming device is arranged along the operational path and engages the plastic sheet to heat it and to form it into a pocket and this is advantageously accomplished when the carrier is held stationary.
