A reversing fiber placement head that is capable of bidirectional fiber placement on an application surface includes a feed mechanism for delivering fiber along two feed paths that are in a V-shaped orientation relative to one another. A pressure tip assembly including a compaction roller receives fiber from the two feed paths and applies the fiber to an application surface. A shifting mechanism shifts the pressure tip assembly from a first position on the fiber placement head to a second position on the fiber placement head to move the compaction roller along a linear path relative to the fiber placement head, allowing the compaction roller to change its direction of rotation in order to apply fiber to the application surface in opposite directions. |
