The author introduces a new algebra which, in addition, is almost a bialgebra; the category of its representations admits a ``truncated'' tensor product. The main result states that the fusion rules (i.e., decompositon of the truncated tensor product in irreducible components) of a family of representations obey the same law as the WZW-model.
