METHOD AND APPARATUS FOR PRODUCTION OF LAMINATED METAL SHEET |
| 摘要 |
<p>A method for a production of a laminated metal sheet which can reduce the ratio of pinholes being caused in a synthetic resin film (the incidence of pinholes) in deep drawing forming of a laminated metal sheet is provided. In order to accomplish this, a method for a production of laminated metal sheet comprising superimposing the heated metal sheet 7 on the synthetic resin film 23 unwound from a film roll, passing the heated metal sheet and the synthetic resin film through one pair of laminating rolls 21 and 21 and the two to be laminated with each other, the laminating process is carried out in the laminating chamber 1 in which the concentration of fine particles having a mean particle diameter exceeding 3 mu m is kept below 100 pieces/ft<3>. <IMAGE></p> |
