ABSTRACT:
A method and apparatus for packaging commodities in tubular flexible packaging material in which the packaging material is drawn from a reel over a mandrel structure, the material is continuously axially slit as it passes over the surface of the mandrel, the severed edges of the material are taken in charge and guided around a product opening in the surface of the mandrel, and brought into sealing juxtaposition and sealed together downstream of the mandrel so that the material reverts to a tube with an axial seam. Commodities can be introduced to the tube through the mandrel interior by introducing the commodities to the product opening or the commodities can be introduced to the downstream end of the mandrel with the tubular packaging material being turned inside-out at this point and being caused to travel back through the mandrel interior and out through the product opening. In either case the tube is closed at intervals on discharge from the mandrel to form discrete commodity-containing packages.
