  • Patent number: 5279699
    Abstract: A sticking apparatus in which a continuous film loaded on a film supply roller is cut off to a prescribed length and a base panel conveyed by a base panel conveyor is moved while said film is stuck, under pressure, to the plate by a pressure sticking roller. Support members for the roller are provided on the body of the apparatus so that the members can be moved rightward or leftward in order that the portion of the film, which is fed from the roller, and the other portion of the film, which is stuck to the plate, are made coincident with each other at the center line of the former portion in the direction of the feed thereof and that of the letter portion in the direction of the conveyance of the panel.

  • Patent number: 5114526
    Abstract: A film bonding apparatus in which a film cut to a length corresponding to that of a base plate is bonded to the surface of the plate by the application of heat and pressure with a bonding roller. The film is provided from a continuous roll and is cut to appropriate size, the trailing edge of the film being held tightly to avoid film wrinkling or air bubbles by the suction action of an edge holding member whose effective length is not less than the maximum width of the films to be bonded by the apparatus. The holding member is moveable, at a speed equal to or slightly less than the rotative circumferential velocity of the pressure roller, the speed being automatically adjusted to maintain appropriate tension on the film. Coordinated movement between the film holding member and the pressure roller is provided by a gear mechanism.

  • Patent number: 5110391
    Abstract: An apparatus for bonding a thin film to the surface of a substrate wherein the film is supplied from a continuous roll to a bonding position where a roller applies heat and pressure to cause the film to be bonded to the substrate. A rotary cutter rapidly cuts the continuous film to a length which fits precisely over the substrate. The cutter comprises a stationary knife and a rotary knife which are disposed on opposite sides of the continuous film. The knives are moveable between a cutting position and a non cutting position and are adjustable to provide in the cutting position a rapid cut of the film transversed to the direction of film travel. The apparatus is operative to hold the leading edge of the film, direct the leading edge to a bonding position at the leading edge of the substrate, hold the film in tension as the film is pressure bonded to the substrate and further hold the film in tension for cutting to its appropriate length.
