OBW half-automatic looping devices are designed for production of German (machine) and English loops (available only on OBW-2) on precoiled extension springs (p.e. on WIM CNC or COM CNC spring coiling machines). With OBW you can produce all kinds of simple loops (loop height from 0.40 to 1.00 times spring media diameter) on right and left coiled springs. With each delivered device you will receive a set-up DVD (available in German and in English) which will allow you to learn very fast how to work with the devices.
