| 8 | Seal roll index | US810874 | 1997-03-05 | US5785794A | 1998-07-28 | Lee B. Fiedler |
| An apparatus for indexing a seal roll which is engagable by a heat seal head to prevent the contact area of said heat seal head from successive landing at the same location on the seal roll includes a driven pulley mounted coaxially with the seal roll and components for indexing to turn the driven pulley. The components include a rocker mounted on a common axis with a drive pulley via a one-way clutch and an actuator connected eccentrically to the rocker such that reciprocating motion of the actuator rotates the rocker in opposite directions. In one direction, the rocker rotates the drive pulley via the one-way clutch to index the roll via the drive belt and driven pulley. In an opposite direction, the clutch permits rotation of the rocker in the opposite direction free of rotation of the drive pulley. A brake member is connected to the rocker eccentrically of the common axis, the brake member clamping the drive belt against a stop member for seizing rotation of the roll during the heat seal procedure. | ||||||

| 10 | Apparatus and method for fabricating breather bags | US226480 | 1994-04-12 | US5536356A | 1996-07-16 | John F. Stuerzel |
| An automated continuous heat sealing apparatus and method are disclosed having dedicated operating stations for fabricating continuous hermetically sealed tubular structures and individual bags from rolls of continuous webs of polymer material, the first web including TYVEK.RTM., as breather bags adapted for gas and steam sterilization. The breather bags are customized to any length depending on the settings of the apparatus. A feeding station holding the rolls of continuous webs longitudinally feeds the continuous webs to a first operating station having a slitter for providing a continuous longitudinal strip of apertures in the second continuous web for cutting material from the slitted second continuous web, and for continuously heat sealing a first set of seams to join the first and second webs. A second operating station continuously heat seals a second set of seams to join the second and third continuous webs for forming a continuous tubular structure. An optional third station intermittently heat seals transverse seams at predetermined lengths along the longitudinal length of the continuous tubular structure, and an optional fourth operating station cuts the continuous tubular structure a predetermined distance from the transverse seams to form individual breather bags. | ||||||

| In an apparatus for making plastic bags or the like from a continuous film of material comprising a sealing drum having at least one seal bar for imparting transverse seals to the film at regularly spaced intervals and a perforator having a rotatable perforator blade for imparting transverse perforations to the film at regularly spaced intervals, the film comprising print marks appearing thereon at regularly spaced intervals, an apparatus and method are disclosed for tracking the positions of each print mark and each perforation and comparing the difference between these positions to a desired difference and thereafter adjusting the angular position of the perforator blade until the difference between the positions of each print mark and each perforation is equal to the desired difference to thereby maintain a desired spacing between each print mark and each perforation. | ||||||
| 12 | Method and apparatus for breaking film perforations | US150949 | 1993-11-12 | US5427294A | 1995-06-27 | Greg J. VandenHeuvel; Christopher E. Dubey |
| A method for breaking film perforations between a plurality of adjacent films employs an in-feed device, an out-feed device, and a festooner positioned between the in-feed device and the out-feed device. The in-feed device and the out-feed device move the plurality of adjacent films downstream through the festooner, which includes a plurality of rollers extending from a rotatable hub shaft. To perform the method, the hub shaft is first rotated to a home position. Next, a first film is fed through the festooner and into the out-feed device using the in-feed device. The out-feed device moves film downstream at a slower speed than the in-feed device. The hub shaft is then rotated at a high boost speed so that the rollers take up slack in the first film generated by the slower speed of the out-feed device relative to the in-feed device. Finally, while the perforations between the first film and an upstream adjacent second film are located between the in-feed device and the festooner, the hub shaft is rotated at a slow speed relative to the high boost speed so as to controllably break the perforations. | ||||||
| 13 | Method of making envelope with tear line formed by ultrasonic energy | US457934 | 1989-12-27 | US5030189A | 1991-07-09 | A. Derrell Hightower |
| Method for forming an envelope having a tear strip or a tear-off flap portion for aiding in opening the envelope, comprising the steps of providing an envelope blank formed of a material capable of being weakened by the application of ultrasonic frequencies, forming the blank into a finished envelope, and applying ultrasonic energy to the finished envelope to form either a pair of closely-spaced, elongate distress lines or a single, straight distress line at which the fibers forming the material are weakened, thus defining a tear strip or a tear-off flap portion capable of manual separation form the remainder of the envelope. An envelope formed according to the above method comprises a body portion having a front panel, a back panel, and a seal flap extending outwardly from and formed integrally with a side of the front panel. The flap has a pair of closely-spaced, elongate distress lines or a single, elongate distress line extending transversely of the flap at which the fibers forming the material are weakened, the distress lines being formed by the application of an ultrasonic frequency and defining a tear strip or a tear-off portion capable of manual separation form the remainder of the flap. The distress lines forming the tear strip can be straight or serpentine. The distress line forming the tear-off portion is straight. | ||||||
| 14 | Plastic film bag with special flap arrangement | US390157 | 1989-08-07 | US5026174A | 1991-06-25 | Eli Blatt |
| A polyethylene or polypropylene bag is provided with a two-section flap. The sections are spaced by a gap, but are connected by Scotch tape which bridges the gap. Part of the adhesive on the tape is exposed through the gap and provides an adhesive strip for the sealing, opening and resealing of the flap. The bag is provided with an ink-receptive characteristic, except in correspondence with the adhesive strip, to assure retention of the adhesive on the tape. The bag can be provided with a mouth closed by the flap and with the opposite end open so that goods can be inserted through the open end and later accessed via the mouth when the flap is opened. | ||||||
