  • Publication number: 20200237054
    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.

  • Patent number: 10702023
    Abstract: Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated manner. For example, shoe parts may be retrieved and temporarily assembled according to preset relative positions to form part stacks. The part stacks may be retrieved with the relative positioning of the shoe parts being maintained and placed at a stitching machine for more permanent attachment via stitching of the parts to form a shoe assembly. Movement during stitching of a conveyance mechanism that transfers the part stack from the stacking surface to the stitching machine and movement of a needle associated with the stitching machine may be controlled by a shared control mechanism such that the movements are synchronized with respect to one another. Vision systems may be leveraged to achieve movement and position information between and at machines and locations.
