    Abstract: A die of a coating apparatus for applying a coating solution includes down- and upstream blocks in a feeding direction of a web, which respectively have a first lip and a second lip. A lip land of the first lip is shorter than a lip land of the second lip in the feeding direction so as to satisfy a predetermined condition. In assembling the coating apparatus, bottoms of down- and upstream blocks are fixed to a fixer with bolts. Between the fixer and the downstream block, a plate member is provided such that the first lip land protrudes from the second lip land.

  • Patent number: 6605320
    Abstract: A coating device for carrying out a die coating method, which is capable of rapidly and assuredly eliminating an undesirable streak occurring in a coating layer during the coating operation. The coating device includes a coating head spaced from a back-up roll, and a shifting mechanism for shifting the coating head close to and remote from the back-up roll. The shifting mechanism includes a reciprocation carriage mounted onto a stationary frame to be linearly reciprocatedly movable thereon, a drive section for reciprocating the reciprocation carriage on the stationary frame, and a stop section for selectively hindering the linear motion of the reciprocation carriage caused by the drive section at a desired position. The shifting mechanism operates to instantaneously reciprocate the coating head at a small distance so that a distance between the outer surface of the back-up roll now carrying out the coating operation and the coating face of the coating head temporarily increases.

  • Patent number: 6592669
    Abstract: An fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move away from one side of the sheet that is toward the curved surface, so that the one side is relatively free of entrained air. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact the web surface primarily with the one relatively air-free side of the coating liquid sheet to decrease the occurrence of skip coating on the web surface, especially when the web is traveling past the applicator at high speeds. The coating is applied in excess onto the web surface and is metered and leveled to a desired coat weight by a downstream doctor.

  • Patent number: 6382128
    Abstract: An apparatus is disclosed for fabricating a laminate product having a pair of sheet materials spaced by a plurality of flexible parallel vanes which are secured to the sheet material so that planar movement of the sheet materials in opposite directions cause the vanes to shift between open and closed positions. The vane material is formed from a web of material by dyeing the material, drying the dyed material, applying spaced longitudinally extending lines of adhesive on opposite faces of the material, and cutting the material into a plurality of side-by-side strips with each strip having a bead of adhesive on each face and along opposite side edges. The cut material with adhesive applied thereto is taken up on a transfer roll and moved to a vane/strip handling station where the strips of material are processed and delivered to a laminating station in parallel overlapping relationship with each other.

  • Patent number: 6372046
    Abstract: A device designed for coating a material web with a coating medium includes a coater, a metering/smoothing device positioned downstream of the coater in the direction of feed of the material web, at a certain distance from the coater, and a support roll around which the material web is guided. Moreover, the material web is guided around the support roll only in the area of the metering/smoothing device, and it traverses essentially in a straight line between the coater and the support roll. In accordance to a first aspect of this invention, a support arrangement supports the material web in the straight web section between the coater and the support roll. In accordance to a second aspect of this invention, devices are provided which stabilize the material web in the area where the web traverses in a straight line.

  • Patent number: 6364952
    Abstract: A coating apparatus for a traveling web comprising two coating heads and a traveling path changing roller is disclosed. A bar coater is arranged close to a pass roller. The bar coater is fixed at such a position as to contact the web when the pass roller is moved down. An extrusion coater is arranged below a backup roller in such a manner as to move up and down. If the pass roller moves up and bends up the traveling path of the web, the web separates from the bar coater. Then, if the extrusion coater moves up, the web is coated with the coating solution by the extrusion coater. If the pass roller and the extrusion coater move down, the web is coated with the coating solution by the bar coater.

  • Patent number: 6346153
    Abstract: An easily operated dispenser for a flexible web typically a cellulosic web is provided that can be operated at a user option to provide a dry web or provide a liquid treated web. The liquid treatment can comprise an antimicrobial liquid treatment suitable for personal contact. The liquid treatment can comprise a cleaner, a soothing lotion, a protective coating, a pharmaceutical treatment, or any other liquid that can provide a beneficial property to a skin surface. The dispenser operates by having a first position from which it provides a dry web. The dispenser can also have a second position which contacts the web with a liquid treatment producing a web containing the liquid treatment composition. The user can interact with the dispenser and place the dispenser in the second position or the first position depending on the user's need for either a wet or dry web. This is a self-contained unit which can be designed to be either a disposable or nondisposable unit.

    Abstract: A method of making shingles includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, and covering the asphalt-coated sheet with granules to form a granule-covered sheet along a longitudinal axis, the granule-covered sheet having a shadow patch thereon, the shadow patch having a first width along the longitudinal axis. The granule-covered sheet is divided into an overlay sheet and an underlay sheet, the shadow patch being on the underlay sheet. A pattern of tabs and cutouts is cut in the overlay sheet, one of the tabs of the pattern being a select tab having a second width along the longitudinal axis, the second width of the select tab being less than the first width of the shadow patches. The relative longitudinal positions of the shadow patch and the select tab are synchronized.
