ABSTRACT:
A product support table, having an elongated longitudinal opening is positioned over a pair of fin seal wheels which provide a seal between two edges of a sheet of film that has been wrapped around an article. The product support table supports a pair of product transport belts that are located between the product being wrapped and the product support table. The belts run the length of the product support table generally in contact with the top side of the table and then, on the return run, are directed upwardly to the bottom of the product support table for most of its travel back to a drive roll and a belt take-up roll.
