Abstract
A fiber reinforced plastic pipe tee is wound around a mandrel according to this method and apparatus. Fiber rovings are delivered to the mandrel by way of a delivery ring translated in an X-Y plane. The mandrel can be rotated around an A axis parallel to the X direction or a B axis parallel to the Y direction. By switching between either rotation around the A axis or around the B axis, a three axis numerical control system can be employed. Means are provided for alternately rotating the mandrel around the A and B axes. Means are provided for independently translating the delivery ring in the X and Y directions as the mandrel rotates. The delivery ring comprises a curved bar around which a band of resin impregnated rovings makes a turn enroute to the mandrel for maintaining a reasonably constant width of the band of rovings.
