  • Patent number: 6521076
    Abstract: A method of manufacturing laminated roofing shingles comprises coating a continuously supplied shingle mat having a width W with roofing asphalt to make an asphalt coated sheet, and subjecting the asphalt coated sheet to one of two subsequent processes. The first process comprises covering the asphalt coated sheet with granules in a first pattern suitable for making laminated shingles with an overlay having tabs and cutouts, where the area of the tabs approximately equals the area of the cutouts, thereby forming a first granule covered sheet. The second process comprises covering the asphalt coated sheet with granules in a second pattern suitable for making laminated shingles with an overlay having tabs and cutouts, where the area of the tabs is substantially greater than the area of the cutouts, thereby forming a second granule covered sheet.

  • Patent number: 6494244
    Abstract: This invention provides a method and apparatus for applying tape tabs to a traveling web, for example, for placement of fastening tabs on a running web of disposable diapers. The invention provides a cutting roll positioned to cut segments from a continuous infeeding web of tape material against a rotating anvil. The anvil, which is traveling at a speed equal to or very close to that of the infeeding tape web, carries the tape segments to a point on its tangency where a higher-speed traveling diaper web most nearly approaches, at which point the traveling diaper web is displaced slightly toward the anvil by means of a protuberance acting against the web. This movement causes it to come into contact with the next available tape segment, which becomes adhered to the higher-speed traveling web. This process provides for operation at higher speeds, higher efficiencies, greater flexibility and lower noise levels than previous processes.

  • Publication number: 20020185217
    Abstract: A slip cutting system sheets an infeed web into discrete articles and merges the articles to a carrier web. The slip cutting system comprises a continuously rotating cutting die having knife blades and packings consecutively around a peripheral surface. The packings cooperate with the knife blades to define a circumferential space between each packing and an associated knife blade. When a packing is at a nip with an anvil roller, the infeed web is drawn in a downstream direction against a drag force. When a circumferential space is at the nip, the infeed web halts downstream motion. When a knife blade is at the nip, the knife blade sheets the infeed web. An insert station cooperates with the cutting die to longitudinally space the articles as they merge to and are propelled downstream by the carrier web. At a subsequent station, the composite web is cut to manufacture individual products.

  • Publication number: 20020000292
    Abstract: A method and an apparatus for cutting a laminate made of a brittle material and a plastic with a cutting tool is described. The plastic is heated up, thereby lowering its viscosity, at least in the region of a predetermined cutting line. A cutting tool is placed onto the plastic side of the laminate, the loading pressure being adjustable. By moving cutting tool relative to the laminate along the predetermined cutting line, the plastic is severed; at the same time the brittle material is scored, thereby inducing a mechanical stress. If appropriate, the mechanical stress along the cutting line is subsequently increased to exceed the rupture strength of the scored brittle material. A preferred application is the cutting of thin glass or glass-ceramic/plastic laminates.

  • Patent number: 6253819
    Abstract: A method and apparatus that produces shaped and laminate articles and recovers the excess material or flash as a part of the manufacturing process. The apparatus uses a combination of rotary die and anvil roller assemblies in successive multiple stations to cut and separate each raw material into final product portions and recyclable flash portions as each raw material enters the apparatus. The apparatus separately reclaims each raw material flash portion and delivers the flash of each material in a recyclable form to an auxiliary recycling operation. In recovering the flash, the apparatus does not adversely affect the speed or quality of production of the final shaped or laminated product. To ease removal of the flash, the apparatus applies lubricant to the blades of the rotary die. To avoid damage to web material, the apparatus uses vacuum belts to convey the web material and web product through the apparatus.
