Abstract
A replaceable liner for installation in a material handling system where materials normally accumulate on an interior of a material handling apparatus, the liner characterized by being sufficiently large so that the liner is externally supported in a first normal direction when the liner is in a working condition, the liner characterized by being sufficiently strong so as to withstand without tearing a frictional sliding force produced by a material sliding along the liner even though the liner may be sufficiently weak so as not to be capable of supporting and confining the material therein; the liner having a first peripheral region for removably securing the liner in a working condition in a conveying apparatus with the liner further characterized by being sufficiently flexible so that the application of a force in a direction opposite to the normal direction liner causes the liner to flex and bend thereby dislodging any materials accumulated thereon.
