ABSTRACT:
An advancing optical fiber (22) is marked with a plurality of spaced indicia along its longitudinal axis. The indicia are applied by an applicator wheel (56) in the form of a disc which is mounted for rotation about an axis which is transverse to the path of travel of the optical fiber. The wheel has a plurality of marking teeth (70-70) arranged about its periphery with each tooth provided with a groove (72) for receiving increments of length of the optical fiber as it is moved rotatably. As the wheel is turned, each tooth in seriatim compresses a porous, resilient pad (80) which is disposed to one side of the wheel in a chamber through which the optical fiber is advanced to cause ink from the pad to be received in the groove of each tooth. Further rotation of the wheel causes ink to be transferred from each groove to the moving fiber. The pad is supplied with ink through a tube by a peristaltic pump (90).
