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.
1. An elastic break brake to allow downstream travel of an elastic thread during machine operation and to stop unwanted elastic travel, said elastic break brake comprising: a base, a base back depending from said base, a pin coupled to said base back said pin having an axis of rotation, and a rotati
1. An elastic break brake to allow downstream travel of an elastic thread during machine operation and to stop unwanted elastic travel, said elastic break brake comprising: a base, a base back depending from said base, a pin coupled to said base back said pin having an axis of rotation, and a rotating cam weight carried by said pin and rotatable coaxially with said axis of rotation;a base elastic retaining surface spaced apart from said rotating cam weight;a nip point between said base elastic retaining surface and said rotating cam weight, said pin vertically aligned with said nip point;said rotating cam weight rotatable in downstream machine direction by elastic traveling under tension between said rotating cam weight and said base elastic retaining surface, allowing passage of said elastic during machine operation, and rotatable in an upstream direction if the elastic is broken to cinch the elastic between the rotating cam weight and the base elastic retaining surface thereby stopping said elastic.
