Abstract
The present invention provides a method for trimming a resin film which can recycle lug portions of the resin film after trimming, can easily trim the resin film even when the resin film is made of resin which becomes fragile by cooling, and enhance the use efficiency of a laminated sheet by making resin coated portions disposed at both sides of the laminated sheet thin. At the time of coating molten resin at least on one surface of a substrate to form a resin film after making the molten resin pass between coating rolls, the lug portions of the resin film are trimmed before the lug portions of the resin film are cooled.
