  • Patent number: 6467667
    Abstract: Device for severing at least one optical fiber When severing optical fibers (1) with conventional severing devices, after the severing operation the severed fibers (1) are distributed in a disorderly manner on the second fixing element (26), with the result that they can only be removed with difficulty and laboriously. Using a bonding device (20, 21) in the form of a rocker (21) with an adhesive strip (20), the fiber ends are adhesively bonded on during the severing operation, with the result that they remain in an orderly manner on the adhesive strip after the severing operation. The rocker (21) is in this case mounted such that it can pivot between an inserting position and a severing position, in order to facilitate the insertion of the fibers (1).

  • Patent number: 6460253
    Abstract: A trimming tool includes a selectable blade attachment for effecting a conversion between a string trimming mode and a blade trimming mode without requiring disassembly of the unit. The assembly includes a locking mechanism selectively engageable with a pivoting trimming blade that pivots between a retracted position and an extended position by centrifugal force. In one embodiment, the locking mechanism is reciprocated between the locked position and the unlocked position based on a rotation direction of the motor. The locking mechanism itself may also be reciprocated by centrifugal force. A spool lock, which is also positioned by centrifugal force, disables automatic string feeding in the blade trimming mode. The trimming tool may also be provided with a blower function incorporating a blower attachment readily attachable as a trimming guard of the trimming tool or a blower assembly integrated into the tool components.

  • Patent number: 6427331
    Abstract: A slitting and shaving tool for separating a coaxial cable with a curved outer surface from an adjacent cable connected to it with a web of insulating material. The tool includes a slitting blade for cutting through the web to separate the cables and a shaving blade with a curved cutting edge for shaving off excess web material to leave a smooth cylindrical outer surface on the coaxial cable. The tool is hinged to swing open, allowing the tool to be used at intermediate locations along the length of a messengered cable. A cable guide surface on the tool body has a double radius to accommodate cables that have a slight bend. The shaving blade is adjustable towards and away from the cable being shaved. A relief hole allows the shaved excess web material to exit the tool. The relief hole is specially shaped to make it easy to position the curved cutting edge of the shaving blade correctly by locating it in alignment with the apparent perimeter of the relief hole.
