| 3 | Radial aligner and folding mechanism | US78772 | 1998-05-14 | US6095961A | 2000-08-01 | Henry J. Mueller; Eliot S. Smithe |
| A series of overlapping envelope blanks are fed into contact with a pull-out roll which engages and accelerates the first blank to separate it from the remaining blanks. From the pull-out roll, the separated blank is fed onto the surface of a rotary aligning wheel. A plurality of aligning pins extend from the surface of the wheel and are positioned in spaced relation around the wheel. The separated blank is fed into contact with the aligning pins forcing the blank with its trailing edge engaged with the pull-out segment to maintain the separated blank aligned on the surface of the wheel. Vacuum ports are positioned on the surface of the wheel adjacent to the aligning pins. The negative pressure from the vacuum ports secures the sheet to the surface of the wheel as the sheet is aligned into a preselected position on the wheel by contact with the pins. The wheel rotates at a lower speed than the pull-out segment and conveys the separated blanks in a radial path to a point on the aligning wheel where each blank is transferred to a folding mechanism where the seal flap of the blank is folded. | ||||||

| 17 | Method of making flapped envelope with peel-off strip for band of pressure-sensitive adhesive | US420887 | 1989-10-13 | US5041072A | 1991-08-20 | E. Leslie McClelland |
| In making the product, the manufacturer coats a longitudinal band of a web with a release coating. A longitudinal pressure-sensitive adhesive strip is applied in a longitudinal band on the web. Transverse glue lines are provided and the web is longitudinally folded, bringing two portions of the web into face-to-face contact. As a result, the transverse glue lines define individual envelope pockets and the release-coated surface on the first web portion becomes applied to the longitudinal adhesive strip on the second web portion. At the same time, the release-coated band of the first web portion is longitudinally severed from the remainder of the first web portion, thereby creating a separate peel-off strip removably covering the band of pressure-sensitive adhesive. The peel-off strip is manufactured while the envelope is being manufactured, and out of the same paper or paper-like material. The manufacturer can print, e.g. in multi-colors, on the portion of the web that becomes the peel-off strip, so that it can bear more attractive, more imaginative graphics, and registration of the peel-off strip on the web is a automatic task. | ||||||

| 20 | Document moistening device | US115219 | 1987-10-30 | US4799989A | 1989-01-24 | Joseph H. Marzullo |
| Apparatus for applying moisture to a flexible document containing a water-activated adhesive. The apparatus includes a reservoir for storing a source of water, a mounting bracket extending from the reservoir, a pivotable hammer pivotably mounted to the bracket and extending toward the reservoir, and a moistening wick extending from the reservoir toward the pivotable hammer. The area between the moistening wick and the pivotable hammer defines a document path. The apparatus further comprises a flexible, one-way gate secured to the lower portion of the hammer for movement therewith, the gate having an end portion extending into the document path. The apparatus also includes a gate deflector secured to the gate and lower hammer portion for movement therewith. Movement of a document up the document path from the gate deflector toward the pivotable hammer causes the gate to flex out of the document path and movement of a document down the document path from the pivotable hammer toward the gate deflector causes the gate to engage the document and bend around the gate deflector to thereby cause the hammer to pivot and urge the document against the wick. Thus, moisture is applied to those portions of the document urged against the wick.The invention is especially useful in combination with a buckle chute folder. | ||||||
