摘要： When the opposing housings (1, 8) of the apparatus are closed, they form between them a small main chamber (P) delimited above by the film (H) for covering the tray and below by the tray (V) itself containing the product (M), and laterally by any suitable mechanical interface structure which surrounds the perimeter of said film and connects it to the perimeter of the upper edge (B) of the tray, this interface structure having holes (22) which are suitably distributed, are located outside the perimeter of the tray, and communicate with said main chamber (P). One or more of these holes (22) open(s) on at least one side of the tray and is/are connected to a first circuit (23, 24), while another one or more of said holes (22′) open(s) on at least one opposing side of the tray and is/are connected to a second circuit (17) which in turn is connected to the inner chambers of the two housings (1, 8). Means (18, 19, 20) are provided to operate in such a way that, in the step of vacuum formation, both said first circuit (24) and said second circuit (17) are connected to vacuum forming means (21) which are kept active for a sufficient time to eliminate some of the air from the inside of the tray and to act in such a way that said first circuit (24) is connected in the next step or at the correct time to means (25) for supplying the process gases, while said second circuit (17) is closed or remains in communication with the vacuum means (21) to ensure that the process gas entering the tray from said first circuit (22, 24) causes the residual air in the tray to flow out from and/or towards said second circuit (22′, 17), thus flushing and saturating the inner volume of the tray, which is subsequently sealed using known steps and means for welding and finally cutting the film (H).

摘要： Between the two housings (1, 18), and below and parallel to the film (F), there is provided a frame (7) having openings (8) with shapes and dimensions suitably greater than the shapes and dimensions in plan view of the underlying trays (V) to be packaged, supported by any means such that, during the closure of the housings (1, 18), this frame (7) interacts with sealing means and contributes to the formation of a main chamber (29) delimited by the upper edge of the tray and by the film above this edge, which is initially connected to the inner chambers (19, 2, 102) of the two housings (1, 18), to enable the air to be removed from these chambers and to form the desired level of vacuum therein, while, in the next step, said main chamber (29) is isolated from the inner chambers of the two housings, so that the process gases for preserving the product can be injected directly into this main chamber, while a corresponding quantity of atmospheric air is directed into said inner chambers of the housings (1, 18) to counterbalance the pressures on the opposite faces of the film which, when the process gases have been fed in, is welded to the edge of the tray and is cut outside this edge by means associated with the upper housing, the whole arrangement being such that, at the end of the cycle, when the housings (1, 18) are opened, no large quantities of process gases are dispersed into the atmosphere, as would be the case in the prior art.

摘要： A machine with a packaging station, at which trays having products are sealed. Opposed parallel sets of belts move in synchronism with each other transversely to the direction of movement of the trays along the packaging station. Each set of belts has an upper belt and a lower belt adjacent to each other and moving in the same direction at the same speed. One end of the adjacent runs receives a sheet of film. A plurality of jaws are located on each of the opposed sets of belts, each set of jaws receiving adjacent runs and an edge of the film. The opposed sets of belts are moveable relatively towards and away from each other, such that the jaws can hold films of different widths and such that the film held therebetween can be stretched and relaxed. A clamp is connected to each set of jaws. The clamp is spring biased to the separate the top and bottom thereof. A power element exerts a selective force onto the bottom of the clamp to close the adjacent runs onto the film. Cams have profiles which, acting through levers, applies a closing force onto the jaws.
