ABSTRACT:
Method and apparatus for correcting reversal points for a traverse for guiding a strand from a reference wheel onto a spool utilize signals indicative of the angular velocity of both a reference wheel and the spool to determine first the actual spool radius at a reference point away from the spool's flanges, then determining the proper spool radius at each reversal point and then determining the actual spool radius at each reversal point. The actual spool radius and the proper spool radius at each reversal point are compared and if a difference greater than a predetermined amount is present, the reversal point is altered by a selected incremental amount.
