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 . the carrier is rotated further through an operational path intersecting a loading or product filling station or stations where the pockets may be filled with articles . subsequently , as the carrier is moved , folding means engage the card to fold it during the movement of the carrier so that a portion thereof overlies the remaining portion having the window . at the end of this movement , the card is positioned to be contacted by sealing means for sealing the card with the pocket . the inventive method includes feeding the cards into a carrier and either separately or coincidentally feeding a plastic sheet thereover , then moving the card into association with forming means for forming the pocket . the forming means advantageously forms pockets on each side of a central folding line so that , when the card is folded , the pockets overlie each other . the card with the pockets is then advanced into a location at which it may be filled with articles , and then it is folded as it is moved into association with sealing means and carried away .
