  • Patent number: 6532327
    Abstract: A method for manufacturing an optical fiber refractive index grating. The method comprises the steps of, providing a substantially twist-free length of an optical fiber between a first spool and a second spool before attaching the first spool and the second spool to a support having a first surface opposite a second surface. The support and spools provide a filament organizer including the first spool as a lockable spool and the second spool as a rotary spool. The filament organizer further comprises a tensioner coupled to the rotary spool to apply tension to at least a central portion of the length of an optical fiber disposed between the lockable spool and the rotary spool.
    Type: Grant
    Filed: March 13, 2001
    Date of Patent: March 11, 2003
    Assignee: 3M Innovative Properties Company

  • Patent number: 6487939
    Abstract: A mechanical stripping apparatus for displacing resin from a resin covered filament by forming a removable sleeve portion between opposing filament ends. The mechanical stripping apparatus comprises a first clamp for holding a filament at a first location and a second clamp having a separation from the first clamp and in axial alignment therewith for holding a filament at a second location. A first set of cutting blades adjacent to the first clamp is positioned for cutting into resin around a resin covered filament proximate to the first location. The mechanical stripping apparatus also includes a second set of cutting blades adjacent to the second clamp for cutting into resin around a resin covered filament proximate to the second location, such that a distance separates the first set of cutting blades from the second set of cutting blades. The distance between sets of cutting blades is less than the separation between the clamps.
