Abstract

PURPOSE:To increase the quality of a fibrous diaphragm, by transposing the fiber layers accumulated to the paper making mesh in the 1st and 2nd transposing processes and drying the fiber layers accumulated to the forming mesh by the warm air after a pressing process at the normal temperature. CONSTITUTION:For making of paper, the fibers suspended in the water are accumulated to the paper making mesh in the same way as conventional, and the 1st transposition is given to the fiber layers accumulated to the paper making mesh to the transposition mesh. Then the 2nd transposition is carried out to shift the fiber layers accumulated to the transposition mesh to the forming mesh. During these processes of transposition, the lumbrical swells produced in the paper making process can be eliminated in a natural way. After this, the fiber layers accumulated to the forming mesh are pressed by the nonheated metal mold of normal temperatures, and the pressed fiber layers are dried by the warm air. In this way, a fibrous diaphragm can be obtained with a light weight, a high rigidity internal loss and excellent homogeneity.
