Wrapping method and apparatus
Abstract:
The disclosure concerns a wrapping machine, a wrapping method, and the package formed by the machine and method. The side edges of a single web are folded around two laterally aligned articles and edge sealed to the remaining web near a central tear line along the single thickness of web interconnecting the packages. By forming two packages from a single web, the web can be run about as fast as any single web used in the known single file wrapping method, whereby the output of the machine in finished packages is substantially doubled over the output of a machine producing packages with the single file method.
