Abstract
A series of elastic break brakes are provided throughout a travel path of elastics in a machine operation. Elastic strands thread through each individual brake mechanism, and if an elastic strand breaks downstream, a natural snap back of the elastic, which ordinarily travels through the system under tension, drives an immediately upstream cam mechanism back, and holds the elastic thread in place at the elastic break brake immediately upstream of the break as to minimize rethreading required downstream of the elastic break brake.
