Abstract
An improved system for making packages includes one or more packaging machines, a storage device for storing film rolls and a transporting device for transporting these film rolls to the packaging machines for loading. The packaging machines are of a type having a cantilevered film-supporting shaft for holding a film roll and sealers for longitudinally sealing overlapped side edges of a film pulled out of a film roll supported by the film-supporting shaft and horizontally sealing tubularly formed film to make bags. The film-supporting shaft extends in the forward-backward direction of the machine such that, when a plurality of these machines are arranged in a mutually side-by-side relationship, their film-supporting shafts are also in a side-by-side relationship and can be easily approached from one direction. The storage device may store the film rolls horizontally or vertically. The transporting device may be a forklift. Conveyors or cranes hung from the ceiling may be used for both for transporting and storing the film rolls. The system may be automated such that a specified film roll at a specified location in the storage device can be automatically transported to and installed in any of the packaging machines.
