The machine is comprised of a frame or support which supports and retains a fixed upper feed hopper to receive and store the material to be packaged, a reciprocating rolling drawer assembly to distribute the material to be packaged alternately to seated operator stations at each end, the drawer assembly consisting of flow-through compartments to allow the packaging...

A pouch machine continuously forms a series of multi-pitch, multi-product pouches in a continuous web of pouch material by folding the web and then forming spaced side seals to define a pouch closed on three sides with an initially unsealed mouth on top. The pouch is opened to its maximum volume prior to filling by pressurizing the pouch. Pressurization is achieved by introducing a curtain of compressed air under a plate and passing the mouths of the pouches adjacent the plate and thus through t...

The method relates to a method for packing articles and/or objects. Articles are packed in an elastic packing material (2) and the elastic packing material is stretched during the packing process. To achieve this, the packing material is arranged in a receptacle (1) in which a partial vacuum is produced. The packing material is stretched due to the pressure that the outside air exerts upon it. The item that is to be packed is then placed in or on the packing material. Once the vacuum has been re...

A process for the production of a hermetic re-closeable package suitable for various products, in particular food products (4), which consists in partly overlapping two (1,2) sheets of flexible material in order to define two longitudinal side edges (1a,2a) overlapping each other, in joining the two edge regions in such a way as to make them separable and recloseable, in locating the product on said sheets, with one side located next to the edge regions sealed in such a way that they are separab...
