| 6 | Forming an envelope around inserts | US40034 | 1993-03-30 | US5568717A | 1996-10-29 | Jimmie A. Harrod |
| 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. | ||||||
| 7 | Apparatus and method for packaging blanks | US200856 | 1994-02-22 | US5385526A | 1995-01-31 | Albert Sigrist; Roberto Rizzolo |
| The blanks (1) are withdrawn one after another from a storage part (20) by transfer means (21) and are disposed on the cylindrical support surface of a drum (3) driven rotatingly by portions of a revolution. Various processing operations are performed on the blanks either while the drum is rotating or while it is stopped, e.g., folding a flap (16), gluing this flap to a surface portion (15) of the blank, or printing a code (17) on part of the blank. The presence, correct positioning, and proper alignment of the blank on the drum are checked before the aforementioned operations are carried out. After they have been effected, the blank is withdrawn from the drum to be sent on to a packaging machine. The processing apparatus and method can be utilized on a line for processing boxes or the like, particularly cigarette boxes, just before they are assembled to receive their contents. They permit a higher rate of production than prior art apparatus and methods, take up less space, and ensure reliable operation owing to a high degree of integration and automation. | ||||||
| 8 | Folding carton blank and method of forming same | US742254 | 1991-08-08 | US5090616A | 1992-02-25 | Raymond O. Bertsch |
| A modified glue flap of a folding carton blank for preventing glue from being squeezed out during the step of adhering the glue flap to the opposite end panel. The face of the glue flap engaged by the glue back-up wheel includes a protrusion near the trailing edge of the flap. Engagement of the protrusion by the back-up wheel causes the glue wheel to skip the trailing area of the flap. The absence of glue in this area prevents glue from being squeezed out when sealing pressure is subsequently applied to the glue flap and the opposite end panel. The protrusion may take the form of an embossed ridge, forming a channel on the opposite side of the protrusion for receiving any excess glue which would have been squeezed out. | ||||||

| 18 | Apparatus for folding paper boxes | US413790 | 1989-09-28 | US5092827A | 1992-03-03 | Hugh A. McAdam, III; Robert Tremblay; James Pacocha |
| Apparatus and a method for folding flaps onto panels formed in folded box blanks, particularly those constructed from corrugated cardboard. As a blank advances along a paper line, a first station engages leading edges of the flaps and forces the flaps into an intermediate plane representing a partial folding operation. Then a second station controls the relative velocities of the flaps along the paper line with respect to the panels to compensate for skew that can occur in other stations. A final station completes the folding operation. The resulting fold is made about an axis, or fold line. If the flap is to be folded about a prestamped score line, the fold and score lines are coextensive. Typically the flaps are folded 180.degree. and the first station produces intermediate folds that are displaced 90.degree. from the panels. | ||||||
