The present invention relates to a method and apparatus for a two-piece box construction which is a continuous, in-line process in which a pair of panels or blanks are fed simultaneously from one end of the apparatus and move along a substantially linear path through the apparatus where they are joined together so that upon exit from such apparatus the joined blanks can be fed directly, in line, into a conventional folder/gluer apparatus for final folding, gluing and other processing.

The invention claimed is: 1. A method for making a multiple piece box from first and second blanks comprising: providing a supply of said first and second blanks in first and second feed members, each of said first blanks having a first connection edge and an outer edge opposite to said first connection edge and each of said second blanks having a second connection edge and an outer edge opposite to said second connection edge; feeding said first and second blanks simultaneously from said first and second feed members and conveying said first and second blanks in a travel direction at the same speed and for the same distance along parallel paths wherein said travel path is parallel to said first and second connection edges and wherein said first and second connection edges of said first and second blanks are parallel and adjacent to one another throughout their conveyance along said paths during said feeding step; applying an adhesive to at least one of said first connection edges; moving at least one of said first and second blanks toward the other of said first and second blanks after said feeding step so that one of said first and second connection edges overlaps the other of said first and second connection edges with the adhesive therebetween; and pressing said first and second connection edges together after said applying step and after said moving step. 2. The method of claim 1 wherein said pressing step forms a multiple piece blank and the process further comprises forming said multiple piece blank into a multiple piece box. 3. The method of claim 2 including aligning the blanks prior to the pressing step until the first blank is in a desired position relative to the second blank. 4. The method of claim 1 being continuous. 5. The method of claim 1 wherein said moving step includes moving each of first and second blanks toward the other. 6. A method for making a multiple piece box from first and second blanks comprising: providing a supply of said first blanks and a supply of said second blanks, each of said first blanks having a first lead edge, a first connection edge and an outer edge opposite to said first connection edge and each of said second blanks having a second lead edge, a second connection edge and an outer edge opposite to said second connection edge; feeding said first and second blanks from said supply of first blanks and said supply of second blanks along parallel paths which are parallel to said first and second connection edges with said first and second connection edges being parallel to and laterally spaced from one another and said first and second lead edges being linearly aligned with one another during said feeding step; applying an adhesive to at least one of said first and second connection edges and thereafter positioning said first and second blanks so that one of said first and second connection edges overlaps the other with said adhesive therebetween; pressing said first and second connection edges together to form a multiple piece blank; and maintaining the first and second lead edges in linear alignment during said feeding, applying and pressing steps. 7. The method of claim 6 including forming said multiple piece blank into a multiple piece box. 8. The method of claim 6 including aligning the blanks until the first blank and the second blank are in a desired position relative to one another before said pressing step. 9. The method of claim 6 wherein said positioning step includes moving both said first and second blanks toward one another to an overlap position. 10. A method for making a multiple piece box from first and second blanks comprising: providing a supply of said first blanks and a supply of said second blanks, each of said first blanks having a first lead edge, a first connection edge and an outer edge opposite to said first connection edge and each of said second blanks having a second lead edge, a second connection edge and an outer edge opposite to said second connection edge; sequentially feeding corresponding said first and second blanks from said supply of first blanks and said supply of second blanks along linear paths at the same speed and for the same distance, wherein said first and second connection edges of said corresponding first and second blanks are laterally spaced from one another and said first and second lead edges of said corresponding first and second blanks are aligned with one another and wherein said linear paths are parallel to said first and second connection edges during said feeding step; applying an adhesive to at least one of said first and second connection edges and thereafter positioning said first and second blanks so that one of said first and second connection edges overlaps the other with said adhesive therebetween; and pressing said first and second connection edges together to form a multiple piece blank. 11. The method of claim 10 including forming said multiple piece blank into a multiple piece box. 12. The method of claim 10 including aligning the blanks until the first blank and the second blank are in a desired position relative to one another before said pressing step. 13. The method of claim 10 wherein said positioning step includes moving both first and second blanks toward one another in an overlap position.
