METHOD AND APPARATUS FOR PRODUCTION OF LAMINATED METAL SHEET

摘要

A method for production of a laminated metal sheet that may have fewer pinholes in a synthetic resin coating when subjected to deep drawing. The method comprises the step of passing a heated metal sheet (7) and an unrolled synthetic resin film (23) through a pair of laminate rolls (21 and 21) to produce a laminated metal sheet under pressure, wherein the above step is carried out in a laminate chamber (1) in which the concentration of fine particles having a mean particle diameter exceeding 3 .mu.m is kept below 100 pcs/ft3.
