Abstract: This invention provides processes for making three-dimensional signage. In one embodiment, a process is provided for making raised graphic signage. In this embodiment, a profile material is adhered to a substrate materials with an adhesive which: (a) bonds firmly enough to hold the profile and substrate materials together during the process, (b) permits the profile and substrate material to be separated after the process is completed, and (c) cures to form a more permanent bond after the profile and substrate materials have been separated. Then, an outline of a desired graphic is cut completely through the profile material. That portion of the profile material which does not constitute the outlined graphic is then separated form the substrate material, before the adhesive forms a permanent bond. In another embodiment, a process is provided for making recessed graphic signage.

Abstract: A method of manufacturing a molding material includes the steps of winding a thin metal strip on the peripheral surface of a rotary shaft a plurality of turns with a resin material being interposed between the resulting layers of metal, cutting an end surface of the metal strip and the resin material which have been wound by a cutting blade while rotating said rotary shaft to obtain a mixture of metal fibers and resin fibers, and heating the fiber mixture to a temperature at which the resin fibers can be softened. In this way, a molding material in which the metal fibers are substantially uniformly dispersed in the resin material in a closely contacted state can be obtained easily. Furthermore, the contents of the metal fibers by volume in the molding material can be arbitrarily adjusted by changing the rate at which the metal strip and the resin material are wound around the rotary shaft.

Abstract: A method and an apparatus is used for forming airlaid articles such as diapers, sanitary napkins and the like. The apparatus includes an anvil drum with die cavities formed therein. The die cavities have foraminous bottom walls for drawing a stream of air-entrained fibrous fluff therethrough. A first material layer is laid on the anvil drum for covering some of the die cavities and is then deformed into the cavities. After a belt with opening corresponding to the die cavities has been laid on the first layer for protecting the sealing areas from fluff, an air stream with fibrous fluff is drawn through the first layer and through the foraminous bottom walls, thus pulling the first layer into the die cavities and causing the fluff to be deposited in the cavities. A second material layer is placed on the deposited fluff and glued or crimped to the first layer. A die-cutting roller then cuts the airlaid articles into the desired shape before the articles are removed from the anvil drum.

Abstract: An engineering method of providing a lining onto the internal face of conduits for gas, city water, etc. that are buried underground. This lining work shall entirely be done from the portions exposed above ground. The distance of the supply pipe to the service tee is measured. The lining tube is set to a length that is slightly longer than this distance. The lining tube is turned inside out inside the supply pipe. As a result, a slightly longer length of non-reverse portion is left inside the supply pipe by the service tee. This non-reverse portion is helpful when cutting the rewinding tape that is tied to the lining tube after the insertion of a cutter. Next the heating tube shall be reversed similarly, and a hot water hose is inserted for circulating hot water in the heating tube. The aforesaid lining tube coated with the thermosetting adhesive is bonded onto the internal face of supply pipe. Next the heating tube is pulled out and the rewinding tape of the lining tube is cut and removed.

Abstract: A film cover is heat-sealed to the open end of containers and cut from a film stock by a cam-actuated, orbitally moving knife blade which severs the film stock along a circumferential region closely adjacent the container's open end. A major extent of the orbital movement of the cam-actuated knife blade about the open-ended container is preferably substantially circular (to closely conform to the circular cross-sectional geometry of open-ended containers to be film-covered). However, a minor segment of the knife blade's orbital movement is cam-actuated so as to follow a segment of an arcuate non-circular (e.g., elliptical) path to form a protruding tab on the film cover so as to allow a consumer to more easily grasp and remove the same. The film is preferably continuously supplied to the sealing and cutting zone, while the waste web (i.e., the film remaining after the film cover has been cut from the film stock) is continuously retrieved from the sealig and cutting zone at substantially constant rates.

Abstract: Labeling apparatus includes a supply of a laminated webs passing through a die cutter for cutting labels in an outer label member on a web liner. A label repositioner includes a peel bar having four flat surfaces forming four sharp edges. The bar is mounted to locate a flat surface as a support surface for the cut web, which passes downwardly over a guide roller located beneath the plane of the flat surface.

Abstract: A composite tape laying machine removes each severed portion of a composite tape of a tape assembly from its backing that is not to be applied to a mold or the like. A removal tape of a material, which has a greater adherence to the composite tape than the backing has to the composite tape to which the composite tape is releasably adhered, is moved into engagement with each non-selected severed portion at least at the start of each non-selected severed portion. When the non-selected severed portion has a varying width, the removal tape is removed from engagement with the non-selected severed portion at the start of its maximum width. When the non-selected severed portion has a constant width, the removal tape is removed from engagement therewith substantially prior to the termination of the non-selected severed portion.

Abstract: Plastic lettering material having a polyvinyl chloride display layer fused with greater adherence onto a release sheet. Including partially carboxylated polyvinyl chloride in the display layer provides substantially increased adhesion, as does a heat-stabilized polyester release sheet. A layer of non-encapsulating thermoplastic adhesive capable of substantially permanent adherence to a smooth substrate is adhered to the display layer surface opposite the release sheet. Outlines of individual lettering elements which together form a sign content are cut through the adhesive and display layers while the release sheet remains substantially uncut, and that portion of the display and adhesive layers not included in the outlines is stripped away. This leaves the lettering elements firmly adhered to the release sheet, maintaining them in alignment during positioning on and heat bonding to a permanent substrate.

Abstract: A multi-entry transaction pad features a plurality of sheets bearing tear-off slips thereon, the sheets being arranged in a stack over a transfer paper in contact with a master record sheet. Peripheral record entry areas on each slip allows sequential entry of transaction-related data thereinto, the entires being recorded immediately thereunder on the master record sheet. The sheets and their slips are offset with respect to each other, and unique transactions-identifying numbers are printed thereon. The slips are staggered in such a way as to be congruent with correspondingly numbered areas on the master record sheet. Offsetting and staggering is arranged so that the record entry area of the next sequential slip is always exposed and in immediate contact with the transfer paper. A relatively large number of tear-off slips are accommodated on a relatively small number of sheets, leading to reduced manufacturing costs and simplification of the manufacturing process. A related manufacturing method is described.
