  • Patent number: 8163115
    Abstract: A method, system and article for producing an envelope having improved seal integrity. The method comprises the steps of disposing at least one material at the interface of the adhesive seal between the flap and the body portion of the envelope, which material exhibits a characteristic property when combined with an activating agent. The envelope is then sealed by closing the flap onto the body portion of the envelope such that the activating agent combines with the material along the sealing interface. The sealing interface is inspected to determine whether the material exhibits the characteristic property thereby confirming that a seal has been produced between the flap and body portion of the envelope. The system and article are directed to the various modules of a mailpiece fabrication system employed to produce the mailpiece including an inspection module for confirming that a seal has been formed.

  • Publication number: 20100316308
    Abstract: A reusable and refoldable bag includes an integral locking mechanism that enables the bag to stay closed in a compact folded position (the folded position is about one-sixth to one-ninth of the original bag size compared to the bag when it is open and laid flat) when not in use and is easily opened when needed to carry contents. The integral locking mechanism includes a covering feature with a protected adhesive element and a flap with a mating adhesive element. In the folded position, the flap's adhesive element is placed under the covering feature and securely interlocks with the protected adhesive element. The locking mechanism can be disengaged and re-engaged for multiple reuses. The flap couples to a first side of the bag and extends outward from the bag. The covering feature couples to the first face adjacent to a top portion of the bag.

  • Publication number: 20010029226
    Abstract: A reclosable packaging bag comprises a main bag body having an opening portion and at least one heat-sealed portion; and a linear fastener provided on the opening portion of the main bag body. The linear fastener is provided along the opening portion of the main bag body by an insert injection molding so as not to extend to the heat-sealed portions. A method for manufacturing the bag comprises the three steps. First, the first and second linear fastening members are formed on a prescribed position of a sheet of film material by an insert injection molding so as to be spaced from each other. These fastening members are engageable with each other to form a linear fastener. Second, the sheet of film material is folded in two so that the fastening members can engage with each other. Third, each of opposite portions of the sheet of film material thus folded is heat-sealed to form side heat-sealed portions.

  • Patent number: 6041569
    Abstract: A mailing machine has an envelope transport device extending longitudinally therethrough and a digital ink jet printing device located adjacent the downstream end of the transport device. Due to the criticality of the spacing between the upper surface of an envelope and the discharge nozzles of the ink jet print head, the envelopes passing through the mailing machine must have their upper surfaces registered with a fixed plane that extends in spaced relationship with the nozzles. The mailing machine includes a flap closing device having fixed and movable elements that can accommodate variations in thickness of the envelopes extending from the registration plane downwardly within a fixed range so that the flap closing device can simultaneously close the flaps of both thin and thick envelopes passing through the mailing machine in a mixed stream.

  • Patent number: 5569145
    Abstract: The invention concerns a method and an apparatus for manufacturing a bag or sack bottom from tubular sections of paper or plastic web. Tubular sections of web material are fed into a feeding plane where they are subsequently sealed along selected seams by a sealing means. The sections are then inverted and fed in parallel to a scoring, gluing and folding section. The tubular section is then inverted again and passed to a pressing section. The tubular sections are stacked on top of each other in a partially overlapping manner as they are passed through the pressing section. After pressing, the tubular sections are passed to a separating station for again separating them before being passed to a packaging station. The invention concerns, moreover, an apparatus for operating the above mentioned method.

  • Patent number: 4877526
    Abstract: A flexible filter bag, the filter element of which is seamless and avoids prior leakage problems, is made by wrapping a flexible, preferably perforated, filtering fabric and a flexible nonfiltering transport material together onto a cylindrical mandrel to provide a tube. A thin metal ring is fitted into the tube, and the portion of the filtering fabric which extends beyond the edge of the transport material is folded inwardly around the ring to provide a cuff. A sleeve of a length about twice that of the tube is inserted into and pulled over the tube until the free ends of the sleeve are approximately coterminous with the ring-free end of the tube. The free ends of the sleeve and tube are gathered in the manner of a sausage casing and then subjected to pressure to form a seal, but the convolutions of the transport material terminate just short of the seal so as to avoid bunching at the seal.

    Abstract: An automatic envelope sealing device wherein envelopes of different sizes can be sealed without adjustment any component of the device. A size of an enveloped supplied into the device is detected by a sensor, and in response to a signal from the sensor, a movable stopper is alternatively extended into a plane in which the envelope is to be fed or retracted in order to stop the large size envelope thereat or retracted therefrom to allow the small size envelope to be fed until it is stopped by a fixed stopper. A flap of the envelope is then bent positively and paste in a controlled amount is applied to the flap whereafter the envelope is fed reversely until it is discharged outside the device. During the reverse feeding, the flap is pressed to be adhered to the envelope by cooperating rollers which act as feeding means.

  • Patent number: 4493685
    Abstract: In making a tubular bag, a first band of thermosetting glue is printed across the length of a web, and a second and third band of such glue is printed on the opposite side of the web in registry with the ends of the first band. The printed glue is then dried with a heat below that of the softening temperature of the thermosetting glue. Glue is applied to a marginal edge of the web and the marginal edges are overlapped and thus glued together as a back seam. An increment of the tube is severed at said bands without heating such bands, and the web is folded along a line extending centrally through the glue bands. The bands are simultaneously clamped together and heated to fuse the bag layers together at the bands.
