ABSTRACT:
A vacuum packaging machine includes a plurality of vacuum chambers (3a,3b) each arranged to receive at least one unsealed product package and operable to perform an independent vacuum sealing operation, each vacuum chamber having a longitudinal direction defined by a direction of travel of the respective product package through the chamber (3a,3b), each chamber having a heat seal assembly (15) therein which extends transversely to the longitudinal direction. An infeed conveyor (17) can be provided with a telescoping portion (17a) which can extend over the heat seal assembly or a part thereof. Each vacuum chamber can have a respective bed (9) and independently moveable hood (11), and the beds (9) can be synchronously vertically moveable. The vacuum packaging machine can be used in combination with a suitable product bagging or wrapping machine.
