Abstract
A graphical subtraction procedure for constructing the perturbative Green functions of light-cone finite, multiply localized products of fields is proposed. The existence of the Green functions as tempered distributions is proved, together with the properties of light-cone finiteness and localization on a line segment. The derivation of light cone expansions is sketched, but not treated in detail.
