Abstract: A compact continuous over end take-off creel system (100' ' ') with a tension control apparatus (110-3) permits unwinding of high tack elastomeric threads from multiple thread packages (105). Thread tension is monitored and controlled through a variable speed motor of a driven take-off roll (130) to maintain continuous operation of the creel system by avoiding breakage of elastomeric threads. Separate motors and thread tension sensors (117), optionally in combination with pretensioners (113A), may be used for groups of threads or for individual threads.
