Abstract
The tape laying head disclosed mounts the laydown rollers for steerability as a unit independently of the steering of the tape head as a whole. The separate steerability of the laydown roller unit is utilized for adaptive steering control in response to edgewise drift of the tape during normal tape laying, as determined by tape edge sensors. When laying tape along a curved path other than the natural path of the tape in free-rolling movement, the laydown roller unit is steered in counterrotation to the steering of the tape head as a whole, thereby to cause a relative axial shift of increments of the tape across its width, enabling the tape to lie flat along a curved course on the lay surface.
