摘要

System and method of smoothing wet paper conservation and restoration by vacuum pressure.; A straightening system wet sheet (1) of paper comprising:; - a plate (10) rigid and moisture resistant, configured to receive said sheet (1);; - A diffusion sheet (14) flexible porous located above the plate, which allows air flow therethrough and inside, with lower plate and above the sheet size; Y,; - a closing sheet (13) and flexible nonporous above the diffusion sheet and the upper diffusion sheet size;; - means of forced air circulation to and from a space defined between the closing sheet and plate through at least one perforation is in contact with the diffusion sheet; Y,; - hermetic sealing means (70) substantially equal the dimensions closing sheet and pressing said closing sheet against the plate when the vacuum is produced by preventing entry or exit of air.; The invention also relates to methods of straightening paper restoration and preservation by vacuum pressure.
