ABSTRACT OF THE INVENTION This invention relates to a method for thin film coating a substrate. The forward end of the substrate is detected to produce a detection signal at a detection position which is before a tacking position. While the substrate is being conveyed from the detection position to the tacking position, tack members are brought close to a surface of the substrate to tack the forward end portion of a web of thin film to the forward end of a surface of the substrate. Conveyance of the substrate is stopped after the forward end of the substrate has been conveyed from the detection position to the tacking position. After the forward end of the substrate is stopped at the tacking position compression-bonding rollers rotate at the tacking position to convey the substrate and adhere the forward end of the thin film to the surface of the substrate at the forward end of the substrate. While said tacked thin film is being adhered to said surface of said substrate, the compression-bonding rollers are moved from the tacking position to near a standby position where the compression- bonding rollers do not touch the tack member 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.
