Abstract
A laser beam (12) scans a filament (8) being wound onto a bobbin (42) sensing the winding angle of attack .beta. and on determining a variance of the angle from a predetermined desired angle generating a signal in a filament position monitor and control (38) for energizing a bobbin carriage drive (40) to correct the winding angle .beta.. Additionally, the laser beam (12) can scan filament (18) before it becomes the last winding on the bobbin (42) and on a climb-back or gap occurring the filament position monitor and control (38) reverses the spindle drive (41) to remove the climb-back or gap and then reassumes normal carriage drive (40) and spindle drive (41).
