Torque balanced rope

Abstract

.Iadd.A torque balanced regular lay wire rope having from three to six strands spiraled together such that the angle of lay of the outer wires in each strand is at least two times greater than the angle of lay of the strands in the rope and said rope is in a stress relieved condition..Iaddend.

We claim: 
     
       1. A torque balanced regular lay .Iadd.wire .Iaddend.rope comprising between three and six strands spiraled together, the angle of lay of the outer wires in each strand being at least . .13/4.!. .Iadd.2 .Iaddend.times that of the angle of lay of the strands in the rope, .Iadd.said rope being in the stress relieved condition, .Iaddend.the torque exerted by the rope being approximately equal to the torque exerted by the strands. 
     
     
       2. A torque balanced regular lay rope according to claim 1 in which the rope will rotate within 3° per ft. of length up to 75% of the breaking strength. 
     
     
       3. A torque balanced regular lay rope according to claim 1 in which the rope is stress relieved at a temperature of between 600° and 1150° F. 
     
     
       4. A torque balanced regular lay rope according to claim 3 in which the rope will rotate within 3° per ft. of length up to 75% of the breaking strength. 
     
     
       5. A torque balanced regular lay rope according to claim 1 in which consists of three strands spiraled together. 
     
     
       6. A torque balanced regular lay rope according to claim 5 in which the rope will rotate within 3° per ft. of length up to 75% of the breaking strength. 
     
     
       7. A torque balanced regular lay rope according to claim 6 in which the rope is stress relieved at a temperature of between 600° and 1150° F. 
     
     
       8. A torque balanced regular lay rope according to claim 1 which consists of six strands spiraled together, the angle of lay of the outer wires in each strand being at least two times that of the angle of lay of the strands in the rope. 
     
     
       9. A torque balanced regular lay rope according to claim 8 in which the rope will rotate within 3° per ft. of length up to 75% of the breaking strength.
