ABSTRACT:
The process relates to the fitting of a bottom of a package formed from a tubular body (1) of non-round section. The open end of the body (1) is inserted between two fixed opposed jaws (M1, M2). Since the distance between the jaws (M1, M2) is less than the distance between the clamped portions (2, 3), the portions (4, 5) which are not clamped deform. Thus, when fitting the bottom, the air escapes and by applying a clamping force to the side walls of the package (1), some of the air still in the body (1) is evacuated before sealing.
