Claim:
A method for producing a shutter ( 2 ) designed to be rolled up and unrolled, comprising: providing on each face, opposite one another, a serrated belt ( 3 , 4 ) comprising a succession of teeth, and adjusting the position of the teeth of at least one of the belts ( 3 , 4 ) to permit both belts ( 3 , 4 ) to mesh, by deforming said belt ( 3 , 4 ) in such a way that both belts ( 3 , 4 ) can mesh, and subsequently stabilizing the mutual position of the belts ( 3 , 4 ) after they are made to mesh, wherein the position of the teeth of at least one of the belts ( 3 , 4 ) is adjusted when at least a part ( 9 ) of said shutter ( 2 ) is being rolled up simultaneously with the belts ( 3 , 4 ), whereby said part ( 9 ) of the shutter ( 2 ) comprises a lateral edge of said shutter, and the position of the belts ( 3 , 4 ) is subsequently stabilized in relation to the shutter ( 2 ) or in relation to said part ( 9 ) of the shutter ( 2 ), and wherein the shutter ( 2 ), or said part ( 9 ) is being rolled up while a belt ( 3 ) which is free in relation to the shutter ( 2 ), or in relation to said part ( 9 ), and which is provided opposite one of the faces of the shutter ( 2 ) or of said part ( 9 ), is made to mesh with a belt ( 4 ) which is fixed in relation to the opposite face of the shutter ( 2 ) or of said part ( 9 ), whereby this meshing takes place while the shutter ( 2 ) or said part ( 9 ) is being rolled up, at a place where the two belts ( 3 , 4 ) make contact, after which the free belt ( 3 ) is fixed in relation to the shutter ( 2 ) or in relation to said part ( 9 ), to the face opposite the one with the fixed belt ( 4 ) while the belts ( 3 , 4 ) mesh.
