ABSTRACT:
To maintain alignment of a band of fiber tows as it travels between a source of such tows and a fiber placement head in a computer controlled fiber placement machine, a pair of redirect rollers are provided, at least one of which is automatically and drivingly swivelled by an amount related to commanded movement of the fiber placement head relative the source of tows so as to maintain alignment of the fiber band between the source and the fiber placement head such that a vector normal the fiber band and across the width thereof is parallel the longitudinal axis of rotation of the redirect roller as the fiber band passes thereover.
