  • Patent number: 6350339
    Abstract: A non-stretchable wound dressing has a flexible, non-stretching cover sheet having adhesive on one side thereof, and having two spaced strip-form gripping tabs at opposite ends thereof. The cover sheet covers a urethane wound dressing with the adhesive of the cover sheet being in contact with the urethane, and the urethane having an adhesive layer on an opposite side thereof. For storage and prior to application to a patient, the adhesive of the urethane wound dressing is in contact with a releasable surface of a carrier, such as cardboard. For application to a patient, one of the cover sheet gripping tabs is pulled so as to release the cover sheet and wound dressing from the carrier, the cover sheet preventing stretching of the wound dressing. The combination is then applied to a patient, again the cover sheet preventing stretching of the wound dressing.

  • Publication number: 20010013215
    Abstract: System, method and material for making pneumatically filled packing cushions in which a plastic film material having two superposed layers joined together along first and second longitudinal edges is prefabricated at a first location by forming longitudinally spaced, transversely extending rows of perforations across it and sealing it together along seal lines which extend from the first edge of the material in a direction generally parallel to the rows of perforations other and terminate a short distance from the second edge to form chambers with open mouths facing the second edge between the rows of perforations. The material is then fan-folded or formed into rolls for storage and shipment. At a second location, gas is introduced into the chambers by passing the material along a tube positioned between the ends of the seals and the second edge of the material and injecting the gas into the open mouths of the chambers through openings in a side wall of the tube.

  • Patent number: 5488816
    Abstract: A ribbon-like flat web having a plurality of side by side depressions is fed through a horizontal slot having a downward facing surface having an aperture communicating with a reservoir of reagent containing solution. The web is urged against the downward facing surface to provide sealing as the solution is fed into the upward facing depressions. The aperture communicating with the reservoir is profiled as a parallelogram having a leading edge which is oblique to the direction of movement. After emerging from the dispensing apparatus the exposed solution is dried in hot air, followed by spray application of a second solution, further drying in hot air, and application of a backing to form capillary chambers. The method is especially useful for manufacturing coagulation assays having magnetic particles and thromboplastin.

  • Patent number: 5459983
    Abstract: A medicine tablet is described as a new article of manufacture. The tablet is enrobed in a gelatin coating formed by application of respective layers of elastic gelatin film to opposite sides of the tablet. The applied gelatin layers conform tightly to the tablet surface, bond securely to the tablet, and are sealed together in essentially edge-to-edge manner at a seal line which extends around the tablet at a desired place on the tablet. The gelatin layers can be colored differently from the tablet and differently from each other. A range of formulations are described for film which can be peelable from a tablet or other product core, and for films which bond to the core. A presently preferred formulation for producing tablets having a bonded tamper-evident coating comprises a water-based gelatin preparation having about 45% gelatin and about 9% plasticizer (glycerin and/or sorbitol) by weight. Method and apparatus for producing such new products are also described.

  • Patent number: 5428937
    Abstract: A machine for packaging newspapers comprises a conveyor which transports a newspaper through an entrance into the machine. The newspaper imparts a tension on both a top sheet, deployed from a first roll, and a bottom sheet, deployed from a second roll. A top and bottom dance bar communicates with the top and bottom sheet, respectively. In response to the tension, each dance bar simultaneously releases a brake and activates an electric motor, causing the first and second rolls to rotate and feed out the top and bottom sheet, respectively. The top and bottom sheet is guided over the top and bottom surface of the newspaper by a pair of first and second edge guides, respectively, for preventing lateral movement of the top and bottom sheets. A cutting and sealing mechanism comprising a front sealing bar is placed into contact with the top and bottom sheets near the rear edge of the newspaper for simultaneously sealing together and cutting the top and bottom sheets.

  • Patent number: 5412925
    Abstract: A product required to be kept in a clean environment is packaged by removing outer layers of a multi-layer film and immediately thereafter introducing its inner core sheet inside a clean room. A bag with an opening is produced inside the clean room by superposing and sealing together two of such core sheets, by splitting one core sheet into two sub-layers and superposing and sealing together these two sub-layers or by folding one core sheet and superposing and sealing together its folded parts. The product may be packaged in such a bag either by using the same apparatus which makes the bag or by using another apparatus. The bag is made of a multi-layered material, and its outer layer is peeled off immediately before it is put inside a clean room to be torn apart and to have the produce taken out.
