The wave of rope for colliery and mining purposes shows many faults in using. The causes to waving come from both manufacturing and using rope.
The wave of rope is formed by plastic bending and twisting. As the curvature and twisting degree, of plastic strain of rope vary with the kinds of ropes, we must take them from the bending and twisting properties, which have been tested preveously for each rope. From these values we can calculate the diameter and pitch of wave in rope.
In this study we explain theoretically the influences of the wave property of wire and the manufacturing condition upon the wave property of rope and the condition to manufacture the waveless rope.
To prevent the wave of rope in using, it is necessary not to form plastic bending and twisting-generally to unwind rope rightly, not to bend or twist rope and not to scrub rope severely.
