Hermitage firefighters responded to a small fire at the Joy Cone Company in Mercer County on Sunday morning.
The call came in just before 9 a.m.
The fire did not disrupt production at the plant.
Officials said the fire started in a piece of machinery that collects dust from cake cone shavings.
This was not the first time the machinery has sparked a fire. In August of 2011, one shift of production was shut down when the fire started in the scrap system.
