Abstract
A method and apparatus are disclosed for preparing box blanks of corrugated board which include feeding the blanks of corrugated board in succession along a feed path and in a direction parallel to opposite edges of the blanks. The blank is folded to form a flat tube prior to its formation into a box. The opposite edges of the folded blank overlap and are reduced in thickness in the areas in which the overlap occurs. Cutting means adjacent to the feed path removes material from opposite faces of the respective edges. The resulting flaps overlap with an unreduced portion of the board of the finished box.
