ABSTRACT:
Disclosed is a tape-laying mechanism and method for constructing sheet layments of composite resin-embedded filamentous material in incremental tape form. A pair of tape-laying heads are mounted side by side for simultaneous operation with their tapes spaced apart an integer multiple of the tape-width. Controlled movement of a tape-laying subcarriage of each mechanism draws tape from a supply before implanting it progressively on the laying surface by return movement of the subcarriage. Tape is laid without movement of the mechanism as a whole other than for lateral indexing, and the mechanism allows lateral indexing while the tape is being drawn out to length above the laying surface before it is implanted.
