  • Patent number: 5289750
    Abstract: An apparatus for bonding thin film supplied from a continuous roll to at least one bonding surface along the entire length of a discrete printed surface base plate and efficiently cutting the film to a proper length which covers an entire planar surface of the board. Each board is conveyed to a film bonding position and the leading end of the continuous film is transported to the film bonding position that is held by suction. A compression bonding roller moves across the surface of the board and automatically feeds film and bonds the film to the board while leaving a portion of the film loose over the trailing end of the board. A cutter comprising a rotary blade and a fixed blade disposed across the direction of movement of the film and the board is mounted on a slide bed which is moveable towards and away from the film. The rotary blade is obliquely oriented in order to permit the cutting of the film when the blade is rotated in opposition to the fixed blade.

  • Patent number: 5162071
    Abstract: A thin film laminating apparatus which is operative to bond a continuous thin film to the surface of a base plate, using heat and pressure applied by a pressure laminating roller, and to cut the film to a length corresponding to that of the base plate. The apparatus has an adjustable film cut-off unit having a fixed cutter and a rotary cutter, both of which extend across the width of the thin film, transverse to the direction of continuous film feed. The fixed cutter and the rotary cutter are independently supported by members which are movable and convey the respective cutters into and out of a film cutting position. The support members are movable manually, to permit initial insertion of the thin film into a cutoff position, and automatically during continuous operation of the thin film laminating apparatus.
