After seven years of operation Accudyne's Automated Laminator continues to produce flat charges that are formed into stringers for the B787. The laminator delivers thermoset prepreg of unidirectional tape, 0/90 fabric and +/- 45 fabric from three distinct supply heads onto a vacuum table. Two separate film heads provide outer face sheets to protect the multi-plied laminate. Laminates are up to 12 inches (305 mm) wide and 36 feet (10.9 meters) long. The machine is capable of local build-ups and drop-offs with a start/stop accuracy of +/- .030 inches (.76 mm). Individual plies are straight to within +/- .030 inches (.76 mm). Material laydown rates are up to 50 lbs/hr (22.7 kg/hr) with the machine producing a laminate every 15 minutes.
