Roughing Patents (Class 69/6.5)
  • Patent number: 11406160
    Abstract: An apparatus for buffing a shoe part includes a housing adapted to be articulated around at least a portion of the footwear part. A rotating spindle is positioned in the housing and has a buffing surface for engagement with the footwear part. A carriage is slideably connected to the housing and holds the spindle such that the buffing surface can be moved closer to and further away from the footwear part. An actuator is in the housing and in contact with the carriage. The actuator applies force to the carriage to increase the force of the buffing surface onto the footwear part. A biasing member is in the housing and in contact with the carriage. The biasing member exerts force onto the carriage in a direction opposite the force exerted by the actuator.
