  • Publication number: 20070283541
    Abstract: A method for manufacturing louvers of a shutter is disclosed. In the method, a roll of paper is cut into several paper sheets according to the weaving width. The paper sheets are soften with water, then the paper sheets can be shaped up after rubbing. The paper sheets are rubbed into several paper threads by a rubbing machine. Those paper threads are weaved to be a paper cloth by a weave machine. The paper cloth is sized and dried by heating so that the paper cloth is solidified. According to the shape of the louver, the paper cloth is cut into several paper louvers having a predetermined shape of the louvers of shutter. Two holes are drilled in the two ends of each paper louvers, so each paper louvers can be integrated in shutter. After that, each paper louvers is shaped by molding, a curved cross-section of paper louver is formed then each paper louvers can resist side pressure.
