ABSTRACT:
A laminated package insert is provided having increased compressive strength for a given weight of board stock, and being easier to erect, as compared to previously known inserts. The insert is made from two substantially identical blanks, with identical score patterns, placed face-to-face and adhered in selected areas, leaving other areas adhesive-free. The score lines are formed so that no score line has to be broken backwards during erection, thereby making erection easier, particularly for automatic insert erecting equipment. A method and apparatus for assembling the insert are also provided wherein two feeders alternately feed blanks into a hopper, each successive pair of blands being face-to-face, one blank having adhesive on selected areas of the face facing the other blank. The synchronization of the two feeders is carefully controlled, as is the settling of the blanks in the hopper, using air jets free of turbulence.
