ABSTRACT:
The tape laying head of a composite tape laying machine is rotatable around the tape laydown surface on circular guideways. The presser shoe assembly is likewise rotatable around the common radius point by means of circular cam faces journalled on cam followers supported by the tape head presser assembly. A feedback transducer signals rotation of the tape presser member while adapting to contour changes, and the signal is employed to effect rotation and realignment of the entire tape head with the presser shoe. The mechanism additionally embodies a brake assembly which is selectively energized to prevent presser shoe rotation at predetermined times.
