Abstract: A vacuum packaging system for vacuumizing and sealing unsealed packages including a plurality of vacuum chambers each linked with a respective platen assembly having a platen and conveyor, each chamber and assembly arranged to receive an unsealed package and perform a vacuum sealing operation on the package, characterized by a) a conveyor apparatus including an in-feed conveyor to load each platen conveyor with an unsealed package, and an out-feed conveyor to unload each vacuumized, sealed package from each platen conveyor; and b) a ferris wheel-type vacuum packaging apparatus including at least three radially arranged vacuum chambers each linked with a respective platen assembly, each chamber and platen assembly rotatable about a central horizontal axis disposed parallel to the linear path of the conveyor apparatus, the ferris wheel-type apparatus operable in a vertical plane of rotation disposed perpendicular to the linear path of the conveyor apparatus.

Abstract: An apparatus for shaping and holding a bag in an open condition, and holding the bag in this condition during loading of the bag with a product, includes an inner stationary ring; a plurality of finger assemblies, each finger assembly comprising a finger adapted to press against the interior of the bag mouth, and a force-transferring member to which the finger is operatively connected; an outer rotatable ring, concentric with the inner ring; a push rod operatively connected to each respective finger assembly; and a motive device adapted to cause rotation of the outer ring relative to the inner ring to effect coordinated radial movement of the fingers relative to the interior surface of the bag. A method of shaping and holding a bag in an open condition, and holding the bag in the shaped, open condition during loading of the bag with a product, is also disclosed.

Abstract: A vacuum packaging machine and a conveyor to deliver a product package from an upstream station to a position adjacent a vacuum chamber. The conveyor has a longitudinal direction defined by the direction of travel of the product package. The vacuum chamber has a heat sealing and cutting assembly oriented transversely to the longitudinal direction of the conveyor and in a position with sufficient spacing between end walls of the vacuum chamber and the assembly for the product package containing two or more products to be loaded into the vacuum chamber with at least one product located in front of the heat sealing and cutting assembly and at least one other product located behind the heat sealing and cutting assembly. The heat sealing and cutting assembly seals and cuts between two products to form two separate evacuated packages.

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.

Abstract: A vacuum packaging machine 141 and a conveyor 17 to deliver a product package from an upstream station 140 to a position adjacent a vacuum chamber 3a. The conveyor 17 has a longitudinal direction defined by the direction of travel of the product package. The vacuum chamber has a heat sealing and cutting assembly 143 oriented transversely to the longitudinal direction of the conveyor and in a position with sufficient spacing between end walls of the vacuum chamber and the assembly 143 for the product package containing two or more products to be loaded into the vacuum chamber 3a with at least one product located in front of the heat sealing and cutting assembly and at least one other product located behind the heat sealing and cutting assembly. The heat sealing and cutting assembly 143 seals and cuts between two products to form two separate evacuated packages.

Abstract: Apparatus for vacuum packing products includes a vacuum packaging machine, an upstream product information acquisition stage arranged to acquire information relating to one or more characteristics of products on a product packing line, and a pack opener arranged to open the mouth of each pack to a controlled extent based on information relating to products being packed acquired at the upstream product information acquistion stage, and to present the pack so that the products are delivered into the open packs which are then delivered into the vacuum packaging machine, or deliver the products into the open packs which are already at least partially entered into the vacuum packaging machine.
