Patent number: 11825915Abstract: 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.Type: GrantFiled: July 1, 2022Date of Patent: November 28, 2023Assignee: NIKE, Inc.Inventors: Dragan Jurkovic, Shih-Yuan Wu, Chia-Wei Chang, Wen-Ruei Chang, Chien-Chun Chen, Chang-Chu Liao, Chia-Hung Lin

Patent number: 11420831Abstract: An apparatus for picking up and positioning an item includes a vacuum assembly capable of applying a suction force to the item. The apparatus further includes an item engaging plate positioned adjacent the vacuum assembly in a first position for engaging with and picking the item. The engaging plate is moveable to a second position by one or more actuators that reduce a suction force experienced at the engaging plate to deposit or place the item. The one or more fans may additionally be controlled to limit a suction force generated during a disengagement operation where the item is being deposited or placed.Type: GrantFiled: December 9, 2019Date of Patent: August 23, 2022Assignee: NIKE, Inc.Inventors: Wen-Ruei Chang, Kuo-Hung Lee, Hung-Yu Wu
