Abstract

Abstract A method of and apparatus for positively holding, and loading and unloading articles such as large empty, light weight, square, slippery plastic milk bottles into and out of a magazine so that they do not jam the handling apparatus. Typically the bottles, after molding, may sometimes be made at the place of business of a plastic manufacturer and used at some other location. The light weight resilience, and slippery surface of empty plastic milk bottles make them extremely difficult to handle. This difficulty is overcome through the use of the present invention in that movement of each bottle is positively guided and handled throughout the entire handling apparatus.
