Abstract
Disclosed is an improved device and method for detecting fiber breakouts and fiber restarts in processes or systems for making fibers from a molten thermoplastic material. In these processes the running fibers induce ambient air into the array of hot fibers close to the nozzles where the fibers are formed, but this air flow essentially ceases when the fiber breaks out. A thermocouple junction located in the path of this airflow will sense temperature changes caused by fiber breakouts and fiber starts. The present invention simplifies and increases the accuracy of prior art sensor systems by eliminating hardware holding this thermocouple and instead uses one or more small holes in a bushing frame plus the refractory used to hold the fiberizing bushing in the frame to hold the thermocouple in the appropriate place.
