these mechanisms work to cut and add on the fly or while the machine is in operation so time is not lost through the use of the cutting and adding mechanisms the excessive scraps normally produced in the lay down are eliminated also cut outs in the design of the part can be accomplished as required the band is delivered onto the mandrel by way of a delivery roller the delivery roller contacts the part surface and provides a compacting force as the fiber is placed through the use of the compaction force the band can be placed into negative contours and follow non geodesic fiber paths the band is guided around the surface of the compaction roller by means of a band biasing device that is a curved deflector that has a contour parallel to the compaction roller and offset from the compaction roller at a nominal clearance the purpose of this device is to keep the band in a ready position for accurately positioning the band on demand for laying down in each sequential lay down pass as the band is layed down onto the mandrel optionally a heat source is provided at the point where the fiber is.
