ABSTRACT:
A packaging machine is provided for packaging articles, using a source of packaging material in the form of a length of plain, plastic tubing. The machine has two stations for faster production. At the first station, the tubing is heat sealed along a strip extending transversely thereof and is severed to form a package section. A separate section with the lower end heat sealed is then transferred to the second station. Here, the upper edges are opened, an article is deposited, and the upper edge is then closed and sealed. The operations at the two stations are performed simultaneously to enable a greater production rate to be achieved.
