Corrugated Box Making Machine and Process


As used herein and as well understood in the industry, corrugated stock refers to a paper product that is also commonly (but somewhat erroneously) referred to as “cardboard.” More properly, corrugated board is formed from one or more pieces of “fluted” paper, a term that describes paper that has been crimped into a somewhat sinusoidal cross section by an appropriate fluting machine-single facer. One or more layers of flat paper typically referred to as “liners” are glued to the fluted layer. Accordingly, many corrugated boxes (as well as corrugated packing inserts and similar structures) are formed of inner and outer liner sheets, with one or more fluting layers in between, and with at least one liner between each fluting layer.
Because corrugated board is typically formed in long running sheets, it must be cut and folded to form boxes by slitting and scoring machine. Typically, the corrugated board (which can be referred to as a “blank”) is first cut and creased to define the portions that will eventually be folded. The blank is then partially folded and a glue strip is applied to one side to fasten it to an overlapping side. The resulting structure is a flattened parallelogram of corrugated board containing cuts and creases that will later define the sides and flaps of the box, and thus its eventual solid rectangular shape. The folding and gluing operation is usually automated, and carried out by a machine referred to as a “folder-gluer.” Aprinting step is often carried out on the blanks at some point in this process. Because the present invention does not generally relate to printing boxes, the specific details of printing will not be discussed in any further detail herein. Boxes are, however, typically printed, folded, and glued one at a time. Because corrugated boxes are often used in large volumes, these individual fattened boxes must be collected, counted, bundled, and stacked into loads for eventual shipment to an end user, typically in the fattened condition.
