Abstract
A product advancement device utilizes a self-coiling plastic sheet of material that has been heat treated to provide the self-coiling properties. The self-coiling sheet is used on an existing shelf to advance products to the front of the shelf without the use of push plates, trays, or other parts to hold the coiled sheet in place, or to prevent it from unrolling laterally or vertically. A portion of the sheet is not coiled during the heating process so that the roll stops at a desired place, providing a product restocking area. The end of the non-coiling sheet, opposite the coiled portion, is formed to provide a product stop barrier at the edge of the shelf.
