Abstract
A production method for a headline sonar cable (20, 120) that exhibits a high breaking-strength and lighter weight than a conventional steel headline sonar cable. Producing the headline sonar cable (20, 120) is characterized by the steps of: a. providing an elongatable internally-located conductive structure (34, 134) that is adapted for data signal transmission; and b. braiding a strength-member jacket layer (52) of polymeric material around the structure (34, 134) while ensuring that the structure (34, 134) is slack when surrounded by the jacket layer (52).
Claims25
A method for producing a headline sonar cable (20, 120) having a high breaking-strength and lighter weight in water than a conventional headline sonar cable having a strength member formed exclusively of steel wire, the method for producing the headline sonar cable (20, 120) comprising steps of:
- a. providing a conductor (22, 122) that is formed so as to be capable of undergoing permanent elongation and that also is adapted for at least data signal transmission;
- b. forming a strength-member jacket layer (52) of polymeric material around at least a portion of the conductor (22, 122) while simultaneously ensuring that the at least a portion of the conductor (22, 122) remains elongatable when enclosed within the strength-member jacket layer (52);
- and
- c. stretching the strength-member jacket layer (52) so as to permanently elongate both the strength member jacket layer (52) and the at least a portion of the conductor (22, 122) while simultaneously not breaking the at least a portion of the conductor.
A headline sonar cable (20, 120) capable of transmitting at least data signals, the headline sonar cable having a strength member and having a conductor, the headline sonar cable having a high breaking-strength and lighter weight in water than a conventional headline sonar cable having a strength member formed exclusively of steel wire, the headline sonar cable produced by a method, the method for producing the headline sonar cable (20, 120) comprising steps of:
- a. providing a conductor (22, 122) that is formed so as to be capable of undergoing permanent elongation and that also is adapted for at least data signal transmission;
- b. forming a strength-member jacket layer (52) of polymeric material around at least a portion of the conductor (22, 122) while simultaneously ensuring that the at least a portion of the conductor (22, 122) remains elongatable when enclosed within the strength-member jacket layer (52);
- and
- c. stretching the strength-member jacket layer (52) so as to permanently elongate both the strength member jacket layer (52) and the at least a portion, of the conductor (22, 122) while simultaneously not breaking the at least a portion of the conductor.
