ABSTRACT:
Rope is made from one or more rolls of film. The rolls of film are loaded onto spindles and tension is applied to the free end of the film of each roll to dispense the films. The dispensing films are each constricted at a common focal point of tension to create substantially triangular portions defined by the line of departure of the film from its roll and the focal point of tension. The triangular portions of each film are continuously simultaneously preconditioned, as by heat or humidity, as the films are dispensed. The rolls are also continuously rotated during dispensation about a common axis which is skewed in relation to the dispensation axes of the rolls, causing the preconditioned films to twist at the focal point of tension into a strand of rope. The strand of rope is then rounded and post-conditioned, perhaps by water or air cooling, and coiled for storage.
