Method of compressing fibrous bodies |
摘要 |
A method of compressing fibrous bodies which are held in place on a perforated support by means of negative pressure. Each fibrous body to be compressed is arranged on a first support that includes parts with and without perforations. A first compression of the fibrous body is then brought about over the part without perforations. The partly compressed fibrous body is then transferred to a second support which includes perforations in a part covered by compressed portions of the fibrous body and a part without perforations covered by uncompressed portions of the fibrous body. A second compression of the fibrous body is brought about in those portions of the fibrous body which cover the part without perforations of the second support.
