<p>PURPOSE:To provide a vacuum lamination method stably laminating a resin film by preventing the involution of air at the time of the lamination of the resin film. CONSTITUTION:Seal rolls 1 holding a metal strip 6 are arranged on the upstream side of press bonding rolls and intermediate rolls 2 are arranged between the press bonding rolls 3 and the seal rolls 1 so as to be in contact with the rolls 1,3 and side surface sealing plates 7 are provided to three sets of the rolls forming pairs to form a surrounded closed space 5 which is, in turn, brought to a pressure reduced state to laminate a resin film 8 to the metal strip. By this vacuum lamination method, an air bubble area ratio at the time of close bonding is reduced to enhance close adhesiveness and the resin film can be stably laminated even in high speed lamination and the quality and productivity of a laminated metal strip can be enhanced.</p> |
