Abstract
A laying head for laying a tube containing an optical fiber onto the outer surface of an elongate support. An upstream end of the laying head provides an inlet for the support and a guide passage for guiding the tube into a chamber of the laying head. The chamber extends around the passline for an angular distance greater than that of the guide passage to allow lateral movement of the tube within the head. The tube passes from the chamber onto the surface of the support as the support exits the chamber. The chamber allows for lateral tube movement to enable the tube to be laid onto the support in spiral fashion with the tube causing the head to rotate around the support.
