Abstract

A packaging apparatus for enveloping an article in a sleeve-type package includes a rigid elongate tube of U-shape and, in use, substantially horizontally oriented with one end secured to a table-top mountable support, the member being otherwise free-standing and having at its other end a cylinder of greater diameter than the tube and within which articles to be packed are locatable. The tube serves as a magazine for a sleeve of netting fed thereonto. The outer end of the sleeve is tied and the sleeve is removed from over said cylinder by an article such as a roll or piece of meat, located in said cylinder, being discharged therefrom, the sleeve being cut at the outer end of said cylinder when the sleeve-enveloped article is remote therefrom, and then tied. The article is discharged from the cylinder by a free-moving piston located therein and operated by air fed through the tube from a supply of compressed air. Air escape ports are provided in the cylinder wall to allow the air to escape after the piston has reached its forward maximum stroke thereby preventing the piston from moving out of the cylinder.
