Abstract
A feed spring for use in displaying items in a display rack is disclosed. The feed spring comprises a sheet of elastic material configured to be formed into a hollow three-dimensional object. The hollow three-dimensional object is secured to the display rack and is compressible to provides a biasing force to position display items in the display rack. The feed spring is maintained as the hollow three-dimensional object in its uncompressed and compressed configurations by interlocking tabs, adhesives, double sided tapes, or other suitable securement mechanism. The feed spring may be suitably secured to the display rack by attachment to the frames of the display rack or other suitable securement means. Preferably, the hollow three-dimensional object in its uncompressed configuration is a hollow cylinder formed by rolling the sheet of elastic material.
