Abstract
A magnetic mark on a cable is subject to loss of intensity. The present disclosure provides for remarking. It utilizes a detector which responds to passage of a magnetic mark on the cable. A coil for remarking is located at a specified and measured distance from the detector. Through the use of measuring wheels in contact with the cable providing data to a computer, the cable traverses from the detector to the marking coil, and a marker control circuit is timely operated to place a new mark on the cable. The new mark is placed coincident over the prior mark and has greater intensity to renew the magnetic marks on the cable.
