Method for manufacturing louvers of a shutter

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.

1 . A method for manufacturing louvers of a shutter, comprising:
 (1) cutting a roll of paper into a plurality of paper sheets;   (2) softening the plurality of paper sheets with water so that the plurality of paper sheets can be shaped up by rubbing;   (3) utilizing a rubbing machine to rub the plurality of paper sheets into a plurality of paper threads;   (4) utilizing a weave machine to weave the plurality of paper threads into a paper cloth;   (5) sizing and drying the paper cloth by heating so that the paper cloth is solidified;   (6) cutting the paper cloth into a plurality of paper louvers that have a predetermined shape of the louvers of the shutter;   (7) drilling holes at two ends of each of the plurality of paper louvers so that each of the plurality of paper louvers is able to be integrated in the shutter;   (8) shaping each of the plurality of paper louvers by molding, wherein a curved cross-section of each of the plurality of paper louvers is formed so that each of the plurality of paper louvers is able to resist side pressure; and   (9) cooling the plurality of paper louvers for hardening.   
     
     
         2 . The method according to  claim 1 , wherein the step (7) of drilling holes can be done after the step (9) of cooling the plurality of paper louvers. 
     
     
         3 . The method according to  claim 1 , when sizing the paper cloth in step (5), a process of coloring the paper cloth is performed at the same time. 
     
     
         4 . The method according to  claim 1 , when the plurality of paper louvers are cut in step (6), deckle edges of the plurality of paper louvers can be shaved off at the same time. 
     
     
         5 . A method for manufacturing louvers of a shutter, comprising:
 (1) cutting a roll of nonwoven fabric into a plurality of nonwoven fabric sheets;   (2) utilizing a rubbing machine to rub the plurality of nonwoven fabric sheets into a plurality of nonwoven fabric threads;   (3) utilizing a weave machine to weave the plurality of nonwoven fabric threads into a nonwoven fabric cloth;   (4) sizing and drying the nonwoven fabric cloth by heating so that the nonwoven fabric cloth is solidified;   (5) cutting the nonwoven fabric cloth into a plurality of nonwoven fabric louvers that have a predetermined shape of the louvers of the shutter;   (6) drilling holes at two ends of each of the plurality of nonwoven fabric louvers so that each of the plurality of nonwoven fabric louvers is able to be integrated in the shutter;   (7) shaping each of the plurality of nonwoven fabric louvers by molding, wherein a curved cross-section of each of the plurality of nonwoven fabric louvers is formed, so that each of the plurality of nonwoven fabric louvers is able to resist side pressure; and   (8) cooling the plurality of nonwoven fabric louvers for hardening.   
     
     
         6 . The method according to  claim 5 , wherein the step (6) of drilling holes can be done after the step (8) of cooling the plurality of nonwoven fabric louvers. 
     
     
         7 . The method according to  claim 5 , when sizing the nonwoven fabric cloth in step (4), a process of coloring the nonwoven fabric cloth is performed at the same time. 
     
     
         8 . The method according to  claim 5 , when the plurality of nonwoven fabric louvers are cut in step (5), deckle edges of the plurality of nonwoven fabric louvers can be shaved off at the same time.
