Abstract: Provided are a process and an apparatus for producing gypsum boards, both of which feature minimized occurrence of defective products and especially excellent continuous productivity and superb efficiency. Making use of the facts that lining paper sheets for gypsum boards are insulators and a gypsum slurry held between the lining paper sheets is a good electrical conductor, a detection of an electric current flowing between an upper forming unit and a lower forming unit or a like method makes it possible to promptly detect any localized tearing which may occur in the overlay paper and/or underlay paper due to an undesired object or the like mixed in during continuous production of gypsum boards and moreover, to readily remove the undesired object or the like as a cause for the tearing without stopping the production of gypsum boards while preventing the localized tearing from spreading over the entire width of the paper.

Abstract: Composite articles are produced by guiding composite tape material through a compaction region where the tape material is pressed onto a substrate, and heating the tape and substrate ahead of the compaction region by irradiating opposing surfaces of the tape and substrate with laser radiation produced by a laser diode array. The laser diode array is divided into independently controllable diode groups, and the diode groups are controlled so as to independently control heating of one area of the tape and substrate relative to another area of the tape and substrate. In one embodiment, the widthwise profile of the light energy is such that a widthwise portion of the tape at an inner radius of a curved path along which the tape is steered at the compaction region is heated to a greater extent than a widthwise portion of the tape at an outer radius of the path.

Abstract: Two surfaces are adhesively bonded together by providing on one of the surfaces a central, single point adhesive contact deposit and providing on one of the surfaces, adhesive extending from a central point deposit in a spoke-like array diagonally across substantially the entire surface. Also provided is the article obtained by the above method as well as the assembly used for bonding the two surfaces together. The surfaces are brought together, one on top of the other, with the adhesive located between the surfaces to cause the adhesive to spread out and cover the surfaces to thereby bond them together.

Abstract: A process and an apparatus for producing endless laminated veneer boards from a veneer-panel strand comprising veneer panels laid together in a plurality of layers by means of gluing and compression in a heated, continuously operating press. The veneer-panel strand is run through a preliminary press with a preheating device before it enters the press. The layers of glue applied to the veneer panels and/or the veneer panels for the center or a central-layer strand have a higher moisture content than the layers of glue and/or the veneer panels for the outer layers or the cover-layer strands. The veneer panels are each then assembled to give an upper and a lower cover-layer strand and, if required, a central-layer strand, and are combined to give a veneer-panel strand.

Abstract: The invention relates to a textured surface covering having a hot melt wear layer and methods of applying the hot melt wear layer to a textured or embossed surface without distortion of the visual image of the textured substrate. The wear layer substantially follows the contours of the substrate with minimum change in thickness of the wear layer over the textured surface and provides an aesthetically pleasing three dimensional appearance to the textured surface of the substrate. Melt applying the melt processable polymer resin to the textured substrate with a conformable pressure roll deter entrapment of bubbles between the wear layer and the textured substrate. Therefore, the wear layer exhibits significant clarity and visual depth, as well as improved maintenance (cleanability) properties. The resulting product has a visual image clarity reflecting any texture in the substrate including very light reflective (lenticular moray) embossings.

Abstract: A method and system for producing a self-mailer using a folding apparatus for folding sheets into folded materials and a tabbing apparatus for sealing the folded materials with tabs in a continuous flow. Typically a folded material exits the folded apparatus with the open end of the folded material leading and this traveling direction of the folded material is not suitable for tabbing. A path directing apparatus is placed between the folding apparatus and the tabbing apparatus so as to cause the folded material to enter the tabbing apparatus with the open end of the folded material leading. As such, the entire process can be carried out without manually reversing the traveling direction of the folded material. In addition, a printer and a labeling device can be added to the self-mailer producing system to put on an address label, a postage indicia and a return address while keeping the process steps in a continuous flow.

Abstract: A method of laminating a structure comprises at least two layers and a photopolymerizable adhesive composition between the layers, at least one of the layers being opaque, colored, or reflective. One or both of the layers is transmissive to actinic radiation in wavelengths in the range of greater than 400 nm and up to 1200 nm. The photopolymerizable adhesive composition absorbs radiation in the identified spectral region of the radiation transmissive layer. Curing is effected by directing radiation in the identified spectral region through the radiation transmissive layer and produces a laminated structure. An underfilled flip chip assembly on an integrated circuit board substrate can be prepared by the method described above.
