A stuffed mailing envelope is formed from webs of paper. A plurality of insert sheets are constructed from webs of insert paper by variably imaging the insert webs, and then intelligently aligning them and cutting them into aligned sheets, and then folding the aligned sheets to produce a formed insert. A plurality of interconnected envelope blanks are formed from an envelope web of paper, and a plurality of insert sheets (including the formed insert) are collected and placed on each of the envelope blanks while they are interconnected in web form. Then, while conveying the interconnected envelope blanks in web form, the blanks are severed from each other and are formed around the inserts to produce a final mailing envelope containing a plurality of insert sheets. The envelope blank typically has two parallel minor flaps and two parallel major flaps. The envelope is formed by sequentially plough folding over the minor flaps, severing the leading interconnected blank from the next blank so that the major flaps are free, changing the direction of conveyance, applying adhesive to the major flaps, and plough folding the major flaps so that the adhesive comes into contact with the minor flaps and the other major flap.

A method of packing stacks of flat articles into packages, whereby a stack is placed along with a wrapping material into a split framework embracing the stack in such a manner that the material wraps it along the upper and two opposite lateral sides, the subsequent bending of the ends of the material to under the lower side of the stack and bending of the end faces of the package being effected in the split framework. The framework used for effecting this method comprises a box open from the bottom and two opposite face sides, the side walls of the box being provided with vertical slots along which the projections of a plate move.

A plurality of interconnected envelope blanks are formed from an envelope web of paper. Die cut windows are also formed in each envelope blank of the interconnected web and transparent window patches are adhesively secured over the die cut window. A plurality of inserts from insert webs of paper are formed and may be variably imaged. The inserts are collected and disposed on the interconnected envelope blanks with address information registering through the window. The interconnected blanks and web form with inserts applied are severed to form discrete envelope blanks and later folded and glued to form complete mailers.

A food wrapping apparatus (10) includes a conveyor (12) for passing unwrapped food product (24) to an elevator platform (14). The elevator platform (14) has a plurality of tucking fingers (16) disposed thereon to provide a yieldable platform. When the food product (24) is disposed on the top of the tucking fingers (16), the elevator platform (14) raises the food product (24) upwards into a layer of wrapping material (18). Tucking arms (36) and (38) are operable to pass under the food product (24) disposed on the top of the tucking fingers (16) and pull the wrapping material (18) therearound. The tucking fingers (16) rotate on longitudinal rods (28) to allow the tucking arms (36) and (38) to pass thereover without disturbing the food product (24). Each of the tucking fingers (16) has a tapered leading end (66) and a tapered trailing end (64). The tapered leading end (66) is designed to mesh with the tapered trailing end (64) of an adjacent one of the fingers (16). The tapered ends allow the meshing of two fingers (16) to occur without binding and without breakage.

The apparatus includes means for providing an article having a sheet of wrapping material draped therearound so that the ends of the sheet project outwardly from one side and along opposing edges of the article. The draped article is moved along a path past a folding work station. The folding work station includes means for folding one of the projecting ends of the sheet underneath the other projecting end in an overlapped relationship on one side of the article. The wrapping material is then sealed along the overlapped ends of the wrapper sheet. The specific embodiments include a particular lifting mechanism used at the folding work station. When heat-sealable wrapping material is used, a heating assembly is disposed at a heat sealing work station. A flat turret chain incorporating a plurality of pockets for receiving the packages to be wrapped is used to move the draped articles along the path.

An automatic machine is disclosed for packaging an array, or slug, of articles, such as cans, in a paperboard carton, wherein the carton is first provided in a flat blank form, is then preliminarily formed into a U-shaped configuration, and then final wrapped around the array of articles, to be subsequently glued up and sealed so as to form a very compact paperboard carton for the articles. The machine includes a frame having a vertically movable elevator structure which is equipped with laterally opposed plows for engaging side panels of the paperboard blank, and for folding the side panels upwardly into a U-shaped configuration around the funnel portion of a packer in which the articles are held prior to being dropped onto the bottom panel of the blank. After the articles are positioned thereon, the elevator structure lowers the U-shaped blank, together with the articles, onto a pocket chain conveyor where the carton is fed laterally off the elevator to fold the top panel, and to fold the end panels associated with the side panels, as well as those associated with the top and bottom panels, into place. A conventional vertical compression unit is also used, and the manufacturer''s tab or flap is glued and folded in this portion of the machine.

A method includes folding leading upper flap of a carton blank, folding a trailing upper flap of a carton blank, and passing the leading and trailing upper flaps in a folded condition into a gap between a pair of guide rails. The method includes interlocking the leading upper flap into a leading can in a pack of product, interlocking the trailing upper flap into a trailing can in a pack of product, and wrapping the carton blank around the pack of product to package the pack of product together.
