  • Publication number: 20090320747
    Abstract: [Object] To provide a roll-to-roll vacuum deposition apparatus capable of easily and speedily adjusting a pressing force between a printing roller and a backup roller. [Solving Means] In the present invention, by adjusting a pressing force between a printing roller and a backup roller through a relative movement of a mask forming unit including the printing roller and a transfer roller with respect to a vacuum chamber, individual adjustments of the printing roller and the transfer roller are eliminated and an adjustment of a pressing force on a unit basis is realized, thus achieving simplification of a structure, simplification and enhancement in precision of tasks, and a reduction in work time.

  • Publication number: 20090324823
    Abstract: [Object] To carry out high-quality deposition processing while effectively maintaining a function of cleaning a can roller by a cleaning unit. [Solving Means] In the present invention, prior to deposition onto a base film, a cleaning unit is brought into contact with a cooling can roller to clean the can roller rotating in a non-cooled state, whereby it becomes possible to prevent excessive cooling of the cleaning unit and inhibit fallaway of removed dust so that the cleaning unit can efficiently carry out dust removal processing of the cooling roller. In addition, by canceling an in-contact state of the cleaning unit and the can roller after the end of the cleaning, the cleaning unit can be prevented from being cooled by a cooling operation of the can roller during deposition, thus making it possible to hold the dust removed from a circumferential surface of the can roller without letting it fall away.

  • Publication number: 20080006206
    Abstract: The object of this invention is to provide a winding type plasma CVD apparatus in which quality of a layer can be made uniform by supplying a reaction gas uniformly to a deposition area of a film, and can perform a self-cleaning process of a deposition portion in the path of deposition onto the film. A film (22) is supported between a pair of movable rollers (33, 34) arranged on the upstream side and downstream side of the deposition portion (25) with regard to the traveling direction of the film, and then the film (22) is made to travel substantially linearly at the deposition position. Consequently, the distance between a shower plate (37) and the film (22) is kept constant, and the quality of the layer is made homogeneous. The film is heated by means of a metal belt (40) traveling simultaneously on the back side of the film. The moveable rollers (33,34) ascend from the deposition position to the self-cleaning position, and the film (22) can be separated from the shower plate (37).

  • Publication number: 20070259105
    Abstract: The problem solved by this Invention is to provide a vacuum evaporation deposition method of the winding type and a vacuum evaporation deposition apparatus of the winding type which can form a metal film on a base film made of single layer plastic film without thermal deformation and with superior productivity. To solve the above problem, there are provided an electron beam irradiator 21 for irradiating an electron beam onto a film material 12 arranged between an unwinding roller 13 and a deposition source 16; an auxiliary roller 18 for guiding the film 12 in contact with the deposited metal layer and arranged between a can roller 14 and a winding roller 15; a DC bias power source 22 for applying a DC voltage between the auxiliary roller 18 and the can roller 14; electricity removing unit 23 for removing electricity from the film 12 and arranged between the can roller 14 and the winding roller 15.

  • Publication number: 20070134426
    Abstract: The invention provides a vacuum evaporation deposition method of the winding type and a vacuum evaporation deposition apparatus of the winding type which can form a metal film on a base film made of a single layer of insulating material such as plastic film without thermal deformation, and which is superior in productivity. An electron beam irradiator 21 irradiates an electron beam onto an insulating material base film 12 before deposition of metal, and a DC bias power source 22 applies bias voltage between an auxiliary roller 18 for guiding the base film 12 with metal film deposited thereon and a can roller 14, whereby the base film 12 charged by the irradiation of the electron beam before the deposition of metal film, is made to be in close contact with the can roller 14. The base film 12 after deposition of metal film is made to be in close contact with the can roller 14 by the bias voltage applied between the auxiliary roller 18 connected electrically to the metal film and the can roller 14.
