<p>A reversing fiber placement head that is capable of bidirectional fiber placement on an application surface (23) includes a feed mechanism for delivering fiber along two feed paths (13, 14) that are in a V-shaped orientation relative to one another. A pressure tip assembly (32) including a compaction roller (16) receives fiber from the two feed paths (13, 14) and applies the fiber to an application surface (23). A shifting mechanism shifts the pressure tip assembly (32) from a first position on the fiber placement head to a second position on the fiber placement head to move the compaction roller (16) along a linear path relative to the fiber placement head, allowing the compaction roller (16) to change its direction of rotation in order to apply fiber to the application surface (23) in opposite directions.</p> |
