Abstract
A non-powered packaging material transporting surface for use in combination with a load support surface of a wrapping apparatus for wrapping a top and bottom of a load is provided. The non-powered packaging material transporting surface includes non-driven rollers aligned in an inline configuration, and a packaging material support guard adjacent to the non-driven rollers. The packaging material support guard bridges gaps between the inline rollers, thereby preventing capture of packaging material between the non-driven rollers. The non-driven rollers rotate as packaging material, wrapped around a load on a top surface of the load support surface and around the non-powered packaging material transporting surface on the underside surface of the load support surface, is moved along the transporting surface.
