Machine for making ropes

Macchina per fabbricare le corde

The model illustrates a large, complex machine for making ropes. The machine is composed of 15 bracket spools arranged in a semi-circle around a cylinder, positioned so that its axis is parallel to the primary threads to be twisted. The drum is made to rotate by means of a winch, so that the tension exerted on it is adequately balanced out. The spools are spun by thin ropes placed in an alternate manner to the left and to the right of the cylinder. The pin of each spool is held in place be a metal bracket secured to the base of the machine. The position and the tension of the rope are adjusted by means of a wedge placed nearby.
