Abstract: We study monoidal structures on the category of (co)modules over a weak bialgebra. Results due to Nill and Szlach\'anyi are unified and extended to infinite algebras. We discuss the coalgebra structure on the source and target space of a weak bialgebra.<br />Comment: 23 pages, to appear in Comm. Algebra
