A ribbonizing apparatus and method for forming a fiber band from a plurality of fiber tows extending along respective fiber tow pathways. The ribbonizing apparatus includes an assembly for selectively heating at least a respective one of the plurality of fiber tows as the fiber tow extends along the fiber pathways. When not needed, the heat is removed from the fiber tow. A plurality of embodiments for accomplishing the method are contemplated.

A filament winding system includes a head that selects the number of tows to be within a winding band while winding and positioning the winding band directly on the mandrel according to contours of the mandrel. Half of the tows are conveyed in an upper portion of the head and the remaining half are conveyed in a lower portion of the head with both halves meeting at an applicating roller at the discharge end of the tows. The head includes cut and add assemblies wherein the individual tows are selectively cut and later can be added to the band.
