Abstract: A method and apparatus for removing residue from an edge of an item are disclosed. The method and apparatus are well-suited to assist in reconditioning used shelving units or deck units for store displays. In various embodiments, ticket holders are removed from the ticket edges of the units. Each unit is then placed on a conveyor and aligned with a guide edge. Optionally, magnets may hold each unit in place on the conveyor. The conveyor moves the units along at least one residue removing machine, and ideally, two residue removing or buffing machines in succession. The residue removing machines ideally include a rotating buffing wheel which strips residue such as glue from the ticket edge of the units. A vacuum can be used to collect debris produced from this process. Sensors may be positioned to sense the front edge of each unit and slide each residue removing machine into operating position at the right time once the front edge of each unit is in residue removing position.
