What does a Mule Spinner do?
Tends mule-spinning frame that spins roving into yarn and winds yarn onto bobbins: Creels machine and threads roving through guides, between feed rollers, and onto bobbins. Starts machine and patrols work area to detect breaks in roving. Stops machine and pieces up broken roving ends. Turns crank to increase or decrease tension of faller wires on yarn according to fullness of bobbins. Doffs full bobbins from machine and replaces them with empty bobbins.
