  • Patent number: 4867836
    Abstract: A film peeling apparatus for peeling a film from a substrate comprises film raising means for raising a part of the film from the substrate, and fluid jetting means for jetting fluid into between the film thus raised and the substrate, the film raising means including a brush or an adhesive member, so that the film the part of which has been raised from the substrate can be readily, positively and instantaneously peeled from the substrate by jetting the fluid.

  • Patent number: 4867837
    Abstract: A film peeler for peeling off a film sticking to a base is used to peel off part of the film sticking to the base, to make that part of the film thus peeled off adhere to a peel direction setting plate and to discharge the film with a film carrying device. The face of the peel direction setting plate where film adheres is formed with a conductive member. The conductive member is provided on an insulating material.

  • Patent number: 4848692
    Abstract: A device for fixing a roller to a rotary shaft, particularly useful with supply and take-up rollers in a laminator device for printed circuit boards, in which only a single tightening operation is required to fix the roller to the shaft. A support member and a press member when assembled together fit inside an end of the roller. A manually rotatable screw threaded to the press member passes through a hole in the support and presses against a sleeve through which the shaft passes and which is press-fitted inside the support member. Guide plates hold the support member and press member in place.

  • Patent number: 4844772
    Abstract: A laminator for cutting a continuous thin film in a predetermined size and laminating same over a substrate is disclosed which comprises a stationary laminator body; a thin film supply member for supplying the continuous thin film to the substrate; a temporary bonding member for temporarily bonding a leading end of the continuous thin film within a pathway of thin film supply; and a support member for supporting the thin film supply member and the temporary bonding member in such a manner that the thin film supply member and the temporary bonding member are movable toward or away from the substrate. The support member is mounted on the stationary laminator body. The laminator also includes a cutter for cutting the continuous thin film in a predetermined size. The cutter is secured to the laminator body in an area near the pathway of thin film supply between the thin film supply member and the substrate.

  • Patent number: 4844758
    Abstract: In a thin film coating method, tack members are brought close to a surface of a substrate to temporarily tack the forward end portion of a web of thin film to the forward end of the substrate. Compression-bonding rollers are then brought into a tacking position where the forward end portion of the thin film is tacked from a standby position where the compression-bonding rollers do not touch the tack members to make compression-bonding contact with the forward end portion of the tacked thin film after the tack members are moved away from the surface of the substrate. The compression-bonding rollers are then rotated at the tacking position for the double purpose of conveying the substrate and adhering the thin film to the substrate.

  • Patent number: 4717441
    Abstract: A laminator for depositing sheets cut from a web into desired lengths onto a base panel using press rolls installed opposite to each other with respect to the base panel and for transferring the base panel deposited with the cut sheets, characterized in that web support means are respectively installed close to the circumferential surfaces of said press roll and moved at the same rate as or slightly lower rate than a circumferential speed of the press roll up to positions close to the contacts between the cut sheets on the base panel and the press roll while the trailing edges of the cut sheets or portions close to the trailing edges thereof are being supported by the web support means.
