Abstract
In a roving winding apparatus applied to a roving frame provided with a plurality of draft parts and corresponding bobbin wheels, a bobbin shaft for driving the bobbin wheel, a bobbin rail on which the bobbin shaft is rotatably horizontally mounted along the longitudinal direction thereof, a lifting motion mechanism for lifting the bobbin rail, and a main motor for driving the draft parts at a predetermined rotational speed, wherein the bobbin shaft is driven under a controlled condition created by a servomotor to follow a digital signal output from the rotation angle detecting device applied to the common bottom front roller of the draft parts, in an adjusted optimal condition under the control of a computer system, incorporated with the lifting motion of the bobbin rail.
