A former arrangement for a rotary printing press is disclosed. The former arrangement includes a former arrangement module with a base element which is mountable on a stationary element of the rotary printing press. A former is connected to the base element. A first web lead device provides for guidance, on the former entry side, of a printing substrate web to be directed in the case of operation over the former. A second web lead device provides for guidance, on the former exit side, of the printing substrate web. The former rests on a cantilevered support element which is fastened with a first end to the base element and which extends cantilevered transverse to a web feed direction over the former.
