ABSTRACT:
A cam shaft of a rotary looper thread take-up is extended short of a thread guide and thus provides a free space there-between. A thread introduced from the tip-end-side of the cam shaft is prevented from being entangled into the cam shaft when the looper thread becomes broken. In a preferred embodiment, three slit-like guides placed in parallel and two cams placed there-between are effective to introduce the looper thread into the rotary looper thread take-up by a simple operation without requiring an operator to visually align the thread to pass through an eyelet.
