A packaging apparatus includes a first holding unit configured to hold a peripheral edge portion of a film on a front side; a second holding unit configured to hold the peripheral edge portion on a rear side; a lifting unit configured to press an article to be packaged to the film; a folding unit configured to fold the peripheral edge portion on the rear side into an underside of the article to be packaged; and an extruding unit configured to extrude the article to be packaged to the front side. The first holding unit moves to decrease tension of the held film after the peripheral edge portion on the rear side starts to be folded into the underside of the article to be packaged before the extruding unit starts to extrude the article to be packaged from the rear side to the front side.

The disclosure is directed to automatic wrapping machines and in particular the disclosure is directed to a machine for wrapping soft enrobed food items with discrete wrapping sheets.

A packaging system according to an aspect is a packaging system formed by connecting an external server to a plurality of packaging apparatuses via a network. The external server stores control parameters for the packaging apparatuses to package an article to be packaged in an optimal state. The packaging apparatus communicates with the external server, downloads necessary control parameters, and controls a packaging operation by using the downloaded control parameters. Accordingly, a setting operation performed in each of the packaging apparatuses can be significantly reduced.

The invention relates to a method of operating a packaging machine for wrapping packaging trays for foods using a packaging film, in particular a plastic film, in which the film is supplied to a holding mechanism having two holding means spaced apart from one another to hold the supplied film at two mutually oppositely disposed sides; in which the spacing of the two holding means from one another is then adjusted: and in which a supplied tray is subsequently pressed toward the supplied film by lifting from below, wherein the holding mechanism is adjusted such that the spacing of the two holding means from one another is reduced.

An assembly system for wrapping an outer wrapper to an inner sleeve to form an outer wall of a double-wall container can include a suction arm. The suction arm can be configured to couple to a suction source and can have a portion defining a suction surface. At least one suction opening can be provided within the suction surface and fluidly coupled to the suction source. A sealing edge can circumscribe at least a portion of the suction surface.
