Braided Electronic Device Cable, Braiding Machine and Method
US Patent 11674245
Published June 13, 2023
Inventors: Robert V. Weber, Redwood City, CA, USA; Min Chul Kim, San Jose, CA, USA; and Jay E. Sha,
Menlo Park, CA, USA
Assignee: Apple Inc., Cupertino, CA, USA
This application relates to cable assemblies with an outer (exterior) layer formed from braiding materials
together. To achieve a desired pattern, a machine tool forming the outer layer undergoes several
modifications. For a machine tool with two tracks (e.g., inner and outer track) with multiple carriers of
material to be braided, each carrier position may include multiple bobbins, with each bobbin carrying a
spool/ coil of the material. During a braiding operation performed by the machine tool, each track rotates
in opposite directions. Moreover, some bobbins include an arm that guides the material in a particular
manner. For example, during rotation of the track, the arm provides a swinging motion, causing the
material carried by the arm to move in a periodic (e.g., sinusoidal) motion. An additional track may be
used to guide the arms.
