Abstract
An end effector, and methods for constructing composite members, in which a compaction roller and redirect rollers translate synchronously along the compaction axis. Additionally, the end effector includes an advantageous arrangement of spools and rollers that directs tow to the redirect rollers at substantially a right angle. Movement of the compaction roller along the compaction axis induces little, if any, changes in tow tension. The substantially constant tow tension advantageously reduces rewinding of the tow supply spools, which can degrade the quality of the lay up and contribute to despooling problems.
