  • Patent number: 8017180
    Abstract: The invention relates to a method for heat transferring high resolution digital images that are printed onto a heat transfer sheet with dye-sublimation inks. The dye-sublimated image/design/graphic is impregnated into a natural wood cellulose web material using a rotary heat transfer press. The imaged wood cellulose web material forms a continuous roll of pre-laminate material that can be bonded/laminated to a myriad of substrates and that can be stored easily in roll form, with or without adhesive backing. This is a unique process of formulating an imaged, environmentally sustainable wood cellulose web material. The raw material can be FSC certified from managed renewable forests and after imaging, the wood cellulose web material has no VOC or formaldehyde emissions. The claimed invention preferably uses a polyurethane reactive (PUR) acrylic top coating that provides a high quality and cost effective surface finish to the decorated wood cellulose web material.

  • Patent number: 5312646
    Abstract: Photographic materials, such as films and papers, include a support and coatings on the support. The coatings often contain hardeners which cause gelation cross links in the binder in the coating. The extent to which the cross-links have formed at the time of processing of the film or paper affects the appearance of the image produced by processing. Conventionally the cross-links have been allowed to form with time in normal atmospheric conditions. According to the invention, the formation of the cross links is accelerated to substantial completion by a process including incubating the material at a temperature above the glass transition temperature of the coating and below the melting point of the coating in an atmosphere having a relative humidity which causes a moisture content of the coating of 0.1 to 0.25 for a period of time sufficient to substantially complete the hardening, that is, the formation of the cross-links.

  • Patent number: 4728396
    Abstract: A coater and a method of operating such coater is disclosed. The method of operating the coater includes the steps of separating a first tail from a full width web unwound from an unwind stand at threading velocity and threading the first tail at the threading velocity through a pull stack. The first tail is widened to the full width of the web so that a full width web extends through the pull stack. The full width web emerging from the pull stack is dumped into a first broke chute which is disposed below the pull stack. The full width web extending through the pull stack is accelerated along with a coating apparatus to coating velocity so that both the full width web and the coating apparatus attain coating velocity. A second tail is cut in the full width web between the unwind stand and the pull stack and such second tail is threaded through the coating apparatus while the second tail is moving at coating velocity.

  • Patent number: 4546011
    Abstract: A web of crepe paper, thin plastic foil or like material convoluted into a roll has an outer side which is provided with a continuous coat of adhesive. Transversely extending, uniformly spaced weakened portion in the form of perforations or slits are formed in the web, and layers of a material which does not adhere to the adhesive are applied to the web. Such layers are applied to the inner side of the web so that they flank the weakened portions and allow for rapid engagement of the leader of the web by two fingers when the user wishes to remove one or more sections or panels between neighboring weakened portions. The roll can be used for the cleaning of garments or for analogous purposes and can be made in an apparatus wherein the application of layers of non-adherent material precedes or follows the making of weakened portions.

  • Patent number: 4539227
    Abstract: A sufficiently thick gliding layer is produced on the recording surface of a record carrier of the type comprising an aluminum layer applied over a lacquer layer coated on a support layer. The back surface of the support layer is also coated with a lacquer layer. A fatty acid or a mixture of fatty acids is admixed with one of the two lacquer layers and a metal-diketone or a metal-keto-ester is admixed with the other lacquer layer in approximately in a stoichiometric ratio to the fatty acid. Following the coating of the material with aluminum in a vacuum, the record carrier material is wound into a roll, and stored.

  • Patent number: 4432301
    Abstract: A method for applying adhesive to a printed paper commercial garment-making rolled pattern marker includes spraying the back (upward facing) side of the marker with a fast-drying adhesive and as the upper surface of the applied adhesive becomes tacky, rolling the marker upon itself. The adhesive remains tacky on the rolled-up marker for a relatively long time, so that it may be used later, when desired, by simply unrolling it tacky side down on top of the fabric to be cut. Apparatus for applying the adhesive includes a variable speed paper-handling mechanism which transfers the marker along a path from an upper feed roll, forward and downward to a take-up roll, and a multiple-nozzle airless spraying mechanism which applies the adhesive to the back side of the marker. The application and paper travel rates are such that the outer surface of the adhesive becomes tacky before the marker is rolled upon itself on the take-up roll.

  • Patent number: 4331727
    Abstract: An adhesive transfer device is disclosed for use in preparing mock-ups of newspaper pages, advertising and the like, by supplying adhesive to the back of the material to be secured to the mock-up. The device includes a substrate carrier having a pair of opposed surfaces and a layer of release coating material coated on each of these faces. An adhesive layer is placed on one of the release coating layers and the substrate is rolled into a roll. This roll is easily unrolled when it is desired to use the adhesive and the adhesive face will then be exposed so that it can be contacted with the specimen, photograph or other article to be placed on the mock-up page. After this contact, when the specimen is pulled from the substrate, the adhesive coating is released from the substrate, remains on the photo, and serves to secure the photo or the like to the mock-up sheet.
