PORTABLE PLASTIC FILM WRAPPING SYSTEM

摘要

A portable plastic film wrapping system comprises a push-cart having a vertical mast member mounted thereon. A film roll carriage is vertically movable along the mast mem- ber, and the film roll carriage is operatively connected to a counterweight which is movably disposed within the mast member. The mast member is provided with a plurality of ap- ertures, and a releasable atop pin is engageable within a particular one of the mast member apertures so as to lock- ingly retain the film roll carriage at a particular eleva- tion when concentric reinforcing wrapping of an article is desired, and is disengageable from the apertures so as to permit the film roll carriage to continuously elevate for spiral wrapping of the article.
