Abstract : The invention comprises an automated tape laying machine, for laying tape on a composite structure. The tape laying machine has a tape laying head with dual tape laying rollers arranged to roll in opposite directions. This eliminates the need for rotation of the tape laying head after each a course of tape is laid. The tape laying head also comprises vertical positioning means for raising and lowering each of the dual rollers individually. The number of tape storage and routing components placed in the tape head has been minimized in order to lighten the tape head structure and make rapid and precise tape head movement possible. In the preferred embodiment of the present invention the automatic tape laying machine comprises a plotting mechanism for positioning a platform above a composite structure. The tape laying head is mounted on the plotting mechanism platform which is capable at controlled movement in two directions. A further aspect of the preferred embodiment comprises a supply carriage having dual supply reels for supply tape through tape guides to each of the tape laydown rollers. The moveable supply carriage mounted adjacent to the plotting structure and can move parallel to the plotting platform. It also preferred that a cutting means be provided at the tape supply carriage for shearing tape material prior to its attachment to the composite structure. In this way, folding of the tape during complex movements of the head is eliminated since each layer of tape is neatly cut. The automated tape laying device utilizes narrow width tape to increase machine flexibility and reduce wastage.
