Abstract
Abstract A method and apparatus for lining bulk box blanks starting with flat, seamed blanks and resulting in flat, lined, tubular blanks. Glue is applied across the length of the seamed blanks excluding the seam regions. After a liner is placed on the adhesive bearing surface of the blank the blank and liner are moved together to a compression station in a direction transverse to the direction of glue application. The liner and blank are pressed together in the compression station and then forwarded to a folding station where the blank quarter sections defined by preformed seams and slits are folded together atop the remaining, intermediate half section to form a flattened tubular blank. While the blank is enroute to the folding station, glue is applied to a flap along the edge of one quarter section to secure the two unattached edges of the blank together to form the tubular blank. The tubular blank is then forwarded to a second compression station secured in its folded configuration by an overhead sled that rotates atop the tubular blank after the folding is completed. At subsequent processing stations the blank is opened and folded to form a box to be filled.
