Abstract
A control for machine members propelled at plural points along their length to move linearly transverse to member length determines and eliminates skew of the driven points. Skew is determined from position indicated by position transducers associated with the driven points. Various types of position transducers are accommodated, including encoders having outputs from which member position can be determined only with reference to marker outputs of the transducer. For such encoders, the control effects velocity controlled motion to detect position. Skew is eliminated by relatively moving the driven points by the magnitude of the skew.
