| 68 | RECLOSABLE POUCH WITH LEAKPROOF CLOSURE AND METHOD OF MANUFACTURE | PCT/US2011058091 | 2011-10-27 | WO2012058428A3 | 2012-08-02 | KARIM ROD M; AGUILAR MIGUEL L; PERALTA ANTONIO |
| An improved sealing method allows the ends of pouch closure to be joined while at the same time forming dome-shaped slider end stops at respective joined ends of the closure. The closure may comprise two zippers. In addition, the ends of the zipper profiles are terminated by means of dies that form uniform and consistent terminations in the zone where the ends of the zipper strips are joined. The dome-shaped slider end stops and the zipper profile terminations are produced by heat sealing, either ultrasonically or through resistance heating, of the closure material. After the closure material has been softened by ultrasonic energy or resistance heating, dies are used to form the dome structures and terminations of the zipper profiles. | ||||||

| This invention pertains to draw tape equipment, and methods for incorporating draw tapes into plastic and like bags. In general, a continuous plastic web is slit at a slitting station to form layers, and respective free edges. The web then passes to a hole forming station where holes are punched in the top and bottom layers adjacent the free edges. After the holes are punched, edge regions of the top and bottom layers are separated from each other, followed by forming of hems in the separated layers at hem forming stations arranged in parallel with each other. Concurrent with forming of the hems, continuous draw tapes are fed to the hem forming stations and the hems are formed about the draw tapes. The formed hems, with the draw tapes incorporated therein, optionally pass through first temperature control stations where the temperature of the plastic web is controlled to a desired temperature before hem sealing. The formed hems are then sealed to the main bodies of the respective top and bottom layers. Narrow pressure wheels apply pressure to the hot seals to improve seal quality. The sealed hems optionally pass through second temperature control stations to cool the web. The edge regions of the layers are then rejoined, in face-to-face relationship with each other. | ||||||

| A thermoplastic bag structure and a method for forming handle-containing bags in roll-form. The method includes the steps of forming a continuous collapsed tube; forming pairs of closely spaced seals transverse to the tube at bag length distances apart; forming a transverse line of weakness between each pair of seals; simultaneously or thereafter folding the marginal edges of the tube inwardly toward each other; forming and removing a cut-out region at one end of each sealed segment of the tube so that on removal of the cut-out region, the cut defines loop handles and a bag mouth region in each bag; again folding the marginal edges of the tube inwardly toward each other; and convolutely winding the structure to form severable bags on a roll. | ||||||
| 77 | Apparatus for making reusable adhesive envelopes | US277594 | 1994-07-20 | US5429576A | 1995-07-04 | Alfred Doderer-Winkler |
| A reusable adhesive envelope and a method and apparatus for making same. The envelope includes a pouch adapted to receive the contents and having an open edge. A flap is mounted adjacent this open edge and may be folded about a flap fold to close the pouch opening. The exterior of the pouch mounts a protective strip. The interior face of the flap mounts a pressure sensitive adhesive, which is initially covered by a release liner. Upon removing the release liner the adhesive on the flap may be secure to the protective strip to close the flap. The flap may be opened and reclosed numerous times. The protective strip and the adhesive/release liner combination are each applied to the envelope as tape strips. With the envelopes in the open configuration these tape strips are alternately applied from a single transfer mechanism. | ||||||
| 78 | Desk-top envelope maker | US031899 | 1993-03-16 | US5426915A | 1995-06-27 | Gil Davidov |
| The invention is directed to an apparatus and method for making an envelope from ordinary size, readily available, writing paper. Preferably, the apparatus is a compact desk-top size machine that can be combined with any common office printer, such as a laser printer, or even be incorporated thereinto to form a single machine. The apparatus enables the provision of a system for integrating and simplifying office computerized printing of letters and addressing of envelopes, by using a single paper tray whereby, for example, following the printing of a letter on one or more sheets of paper, the subsequently fed final sheet of paper from the paper tray is routed to the envelope making apparatus, perhaps after the printing of an address on the final sheet, whereby an envelope is created. The envelope is created by the apparatus by appropriate scoring or creasing of fold lines, as well as cutting the sides of the sheet of paper to form side flaps, for example, and the application of a suitable adhesive for sealing the bottom flap to the side flaps, for example, as well as the application of an adhesive on the sealing flap for subsequent sealing by the user, for example, following the insertion of the typed letter, for example, into the thus created envelope. Thus, by means of the apparatus, a method is devised for integrating the letter and envelope addressing and graphics, such as a logo to be impressed or printed on the envelope, with the same computer program at the same time and with the same printing means. Thus there is a significant economic saving in producing envelopes oneself from relatively inexpensive writing paper. With the apparatus according to the invention, it is also possible to make mailers from ordinary sheets of paper already carrying a message, thus saving the cost and bother of using and handling both a letter and an envelope. | ||||||

| Apparatus for producing handled bags includes a web dispenser; a perforator for creating perforated seams transversely across the web at predetermined intervals to generate a succession of adjacent web sections; means for attaching at least one handle to each web section; a tube forming mechanism for configuring the web into a tubular configuration; a separating device for breaking the perforated seams to separate the adjacent web sections without disturbing the handles; and a bottom forming mechanism for closing the bottom end of each separated web section. The separating device includes a rotatable first breaker roll having a pressure bar provided thereon and a rotatable second breaker roll having a cooperating gap formed therein for receiving the pressure bar as the first and second breaker rolls are synchronously rotated with the web fed therebetween. The pressure bar includes a contoured edge surface with relief notches appropriately formed therein to receive the handles; and the cooperating gap includes angled sidewalls and is provided with a resilient material therein. A method for performing various steps in accordance with the elements of the apparatus is also included. | ||||||
| 80 | Registration process | US81906 | 1993-06-23 | US5421802A | 1995-06-06 | Harry A. Landeck; Alan F. Savicki |
| The present invention features a high-speed registration system for the manufacture of plastic bags. The system has a registration apparatus that senses the leading and trailing edge of each sinusoidally-shaped tie pattern from a continuous web. Each sinusoidally-shaped tie is associated with an individual bag entity and, therefore, represents a midway point for each bag to be cut from the continuous web. The leading and trailing edge of each sinusoidally-shaped tie, therefore, is used to determine the center line of each bag. A plurality of center line determinations are averaged upstream of the sizing apparatus. When a detected entity finally reaches the downstream sizing apparatus, the cutting of the individual bag unit from the web is accomplished about an accurate, but "floating", center line | ||||||
