Apparatus for winding a roving applied to a roving frame.

摘要

In a roving winding apparatus applied to a roving frame provided with a plurality of draft parts (7) and corresponding bobbin wheels (21), a bobbin shaft (23) for driving the bobbin wheel (21), a bobbin rail (20) whereon the bobbin shaft (23) is rotatably mounted horizontally along the longitudinal direction thereof, a lifting motion mechanism (56-59) for lifting the bobbin rail (20), and a main motor (1) for driving the draft parts (7) at a predetermined rotation speed, wherein the bobbin shaft (23) is driven under a controlled condition created by a servomotor (SM) to follow a digital signal output from the rotation angle detecting device (PG) applied to the common bottom front roller (8) of the draft parts (7), in an adjusted optimal condition under the control of a computer system (100), incorporated with the lifting motion of the bobbin rail (20).
