Abstract
A method and apparatus for heat stretching a synthetic fiber rope. The rope is attached to tensioning members and suspended in a liquid medium so that this extends in a generally horizontal direction. The liquid medium has a specific gravity which is approximately equal to that of the rope at the desired stretching temperature, so that the rope is buoyed by this in order to relieve the weight of the segment from the tensioning members. The liquid medium is then heated so that the rope is uniformly heated to the stretching temperature, and tension is applied between the tensioning members so as to stretch the segment of rope to a predetermined increase in length.
