Abstract: A creel system includes a plurality of tension controller apparatuses that hold spools of wire. The tension controller apparatuses apply tension to the wire and may be manipulated to fine-tune or control the tension applied to the wire. The creel system may further include a plurality of sensors that measure operation of the creel system as well as the condition of the wire. In such embodiments, the creel system may include a user-interface that provides data to the operator in real time and with which the operator may interact to control operation of the creel system.
