ABSTRACT:
A bag forming and filling apparatus in which a continuous tube of heat sealable plastic is fed from a roll along a pathway where it is cut to the desired length and sealed on one end. The opposite end of the sealed tubing engages over an expandable hollow mandrel which expands the open end of the tube to permit material to be inserted therein. The filled section of tubing is then fed in reverse along the same path to a point of storage or use.
