Abstract
A cable adapted to transmit torque in rigging or furling a sail of a boat includes a core having at least one termination end and a bight, and at least one layer of fiber wound around the core, wherein a fiber in a portion of the fiber layer disposed over a center portion of the bight has a first pitch angle relative to a longitudinal axis of the core and wherein a fiber in a portion of the fiber layer disposed over the at least one termination end has a second pitch angle relative to the longitudinal axis of the core. The fiber layer includes a transition zone disposed between the at least one termination end and the center portion, wherein a fiber in the transition zone has an orientation that transitions from the first pitch angle to the second pitch angle.
Claims22
A cable adapted to transmit torque in rigging or furling a sail, said cable comprising:
- a core having at least one termination end and a bight;
- and
- at least one layer of fiber wound around said core;
- wherein a fiber in a portion of said fiber layer disposed over a center portion of said bight has a first pitch angle relative to a longitudinal axis of said core;
- wherein a fiber in a portion of said fiber layer disposed over said at least one termination end has a second pitch angle relative to said longitudinal axis of said core;
- and
- wherein said fiber layer comprises a transition zone disposed between said at least one termination end and said center portion of said bight, wherein fiber in said transition zone has an orientation that transitions from said first pitch angle to said second pitch angle.
A cable adapted to transmit torque in rigging or furling a sail, said cable comprising:
- a core having at least one termination end and a bight;
- and
- a plurality of layers of fiber concentrically wound around said core;
- wherein a first fiber layer of said plurality of fiber layers has a portion having at least one fiber that is disposed over a center portion of said bight and that has a first pitch angle relative to a longitudinal axis of said core;
- wherein said first fiber layer has a portion having at least one fiber that is disposed over said at least one termination end and that has a second pitch angle relative to said longitudinal axis of said core;
- wherein said first fiber layer comprises a first transition zone disposed between said at least one termination end and said center portion of said bight, wherein at least one fiber in said first transition zone has an orientation that transitions from the first pitch angle to the second pitch angle;
- wherein a second fiber layer of said plurality of fiber layers has a portion having at least one fiber that is disposed over said center portion of said bight and that has a third pitch angle relative to said longitudinal axis of said core;
- wherein said second fiber layer has a portion having at least one fiber that is disposed over said at least one termination end and that has a fourth pitch angle relative to said longitudinal axis of said core;
- and
- wherein said second fiber layer comprises a second transition zone disposed between said at least one termination end and said center portion of said bight, wherein at least one fiber in said second transition zone has an orientation that transitions from the third pitch angle to the forth pitch angle.
