The invention relates to a process and apparatus for packaging, continuously and under vacuum, individual articles in the form of plates or sheets in a wrapping sheet folded along its longitudinal axis. The articles (6, 7, 8) are introduced within the fold (1) of the wrapping sheet (9); the two free edges of the wrapping sheet (9) are brought close in order to delimit a substantially enclosed space; a partial vacuum is applied at the base (1) of the fold inside the space such defined; and the open edges (2, 3, 4) surrounding each article are welded. |
