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.

Claims1

Dependent claims

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 rotating weight carried by a pin coupled to a base;
a base elastic retaining surface spaced apart from said rotating cam weight;
said rotating cam weight rotatable by elastic traveling under tension between said rotating cam weight and said base elastic retaining surface, said elastic causing said cam weight to be slightly rotated in a downstream machine direction allowing passage of said elastic during machine operation, and stopping said elastic by rotating said cam weight slightly in an upstream machine direction if said elastic is broken.

Dependencies are inferred from the claim text.
