  • Patent number: 6294033
    Abstract: The invention provides a lamination apparatus including using a sheet roll with an encoder plate secured to the end face of an adhesive sheet roll, and a slit pattern on the encoder plate being detected by a photointerruptor. In addition, a duty ratio is calculated on the basis of rectangular pulse signals output from the photointerruptor, thereby identifying the type of the adhesive sheet roll. Further, the period of the rectangular pulse signals output from the photointerruptor is compared with a predetermined value, such that the trailing edge of the adhesive sheet of the adhesive sheet roll is detected at the time point when the period is smaller than the predetermined value.

  • Patent number: 6223799
    Abstract: Colored or metallic foil is applied to toner printed onto a substrate, such as paper, in a high speed, versatile manner, using a rotating impression cylinder, and a rotating transfer cylinder having circumferentially spaced heated raised portions. The toner, which preferably includes a thermoplastic component, is applied to the paper with any suitable printer, such as a computer controlled MIDAX (ion deposition) print engine. The toner may be heated by an infra red heater just before the paper is fed to the nip between the impression and transfer cylinders. A foil strip having an adhesive layer facing outwardly, a foil layer, and a release coating on a backing, is also fed to the nip, and the backing taken up downstream of the nip. Heat and pressure applied at the nip transfer the adhesive and foil from the foil strip to the tacky toner, producing the desired foil printed paper, which then may be further processed.

  • Patent number: 5961768
    Abstract: The adhesive sheet is a three-layered construction formed from a base material, a plyimide base resin adhesive and a release film, and is outputted from a sheet output control portion. A plate-shaped material comprised of semiconductor wafer is placed on a bonding table, and the wafer is heated by a heater unit. The bonding table is moved to the upper position, then a press roller is moved to press the adhesive sheet onto the heated wafer so as to bond the adhesive sheet to the wafer. At such time, another press roller presses the adhesive sheet. Then, a cutting unit is lowered to cut away any excess adhesive sheet material from the outer periphery of the wafer. Then, such excess adhesive sheet material is wound up in a sheet wind-up portion. In the next step, the rear surface of the wafer is stuck to a dicing tape, and then each chip is cut out. After this is done, each chip is picked up from the dicing tape and die bonded to a lead frame via the adhesive sheet.

  • Patent number: 5951816
    Abstract: The labyrinth path in the corrugating nip of a single facer is substantially reduced by utilizing a small diameter corrugating roll captured between a larger diameter conventional corrugating roll and a backing roll arrangement. The smaller diameter corrugating roll is captured to prevent bending thereof under corrugating loads. The corrugator may be operated at high speeds without the adverse increase in labyrinth path and web tension characteristic of a pair of large diameter corrugating rolls.
