Abstract:
A device for producing a fibrous sheet, including a water squeezing section which squeezes the dispersion medium from a dispersion to generate a web, and a drying section which dries the web to generate a fibrous sheet, the water squeezing section having multiple first fabric sheets arranged longitudinally along the transport direction of a web substrate that is partway through web generation, and water squeezing units which are provided beneath the multiple first fabric sheets and squeeze the dispersion medium from the dispersion, and in the water squeezing section, a continuous sheet is positioned so as to extend over the upper surface of the multiple first fabric sheets, and the dispersion is discharged onto the upper surface of the continuous sheet.
