Anotations

Scope note:

Mechanized devices designed to draw out, attentuate, and twist wool, cotton, or other types of sliver in preparation for subsequent spinning processes. Historically fueled by leather belts transferring power from a mill's steam engine, these devices drastically expedite the roving process in a factory-based textile manufacturing system.
