Abstract
A compaction device for use with an automated fiber placement machine includes multiple compaction rollers mounted for independent displacement on a supporting frame. The attitude of the compaction rollers change relative to each other when fiber tows are laid up at an angle over an edge of a tool in order to maintain compaction pressure on the tows and thereby reduce non-compacted areas of the tows.
