Veneziano partial-wave amplitudes are unitarized by the truncated N/D method. The N functions are extrapolated directly from the Veneziano partial- wave amplitudes. Sum rules for inelastic functions are derived from the assumption that the spectrum and the residues of the rules, the behavior of inelastic functions and the inelastic widths of the resonances can be estimated given a single elastic scattering amplitude of the Veneziano model. An explicit application of this method to the pi pi I= 1 p-wave amplitude is given. (auth)
