<p>Designed for bobbin winding operations, the impulses generated at the bobbin shaft, together with parameters of yarn size and the like, are added progressively by every third impulse to a step motor to reduce the bobbin speed to compensate for its increasing dia. and to limit the movement of the yarn guide to develop the required conical shape at the ends. The purpose is to replace conventional complex mechanical linkages with a simple control system.</p> |
