Abstract
A method and apparatus for heat stretching a synthetic fiber rope. The rope is buoyed in a vessel containing a liquid medium, and this is heated to a predetermined stretching temperature. Tension is applied to the heated portion of the rope so as to stretch this to a predetermined increase in length. The process may be batchwise, or it may be continuous. In the batch process, a length of the rope is stretched in the heating vessel by a draw rod. In the continuous process, feed and take-up capstans pass the rope through a heating chamber, and then through a cooling chamber. The capstans are operated at different speeds so that the rope is tensioned and stretched between them within the vessel.
