Patent ID: 7448185

Claim:
A method of making packages with an internal header from an elongated web of preformed interconnected bags, where each bag is defined by first and second plies of the web, first and second side edges of the web that hermetically join the first and second plies, a preformed seal extending between the first and second side edges, a line of separation in the first ply extending between the first and second side edges, and a line of weakness in the second ply extending between the first and second side edges, the method comprising: a) moving one of the web and a single seal bar relative to the other to a first position that corresponds to a desired boundary of a first compartment; b) moving the first ply away from the second ply at the line of separation to form a bag opening; c) inserting a selected one of a product and a header into the bag through the opening; d) with the single seal bar, sealing the first and second plies together to form the first compartment that contains the selected one; e) inserting an other of the product and the header into the bag through the opening; f) moving the one of the web and the single seal bar to a second position that corresponds to a desired boundary of a second compartment, wherein the step of moving the one of the web and the single seal bar to a second position is performed by indexing the web to a second position; g) with the single seal bar, sealing the first and second plies together to form the second compartment that contains the other; and h) breaking the second ply along the line of weakness to separate the package from the elongated web of interconnected bags.
