The method includes separately supplying a first substrate web (31) and a second substrate web (32) to a continuous, multi-stage rod-forming process that includes at least a first stage and a subsequent second stage. The method further comprises supplying a continuous susceptor profile (20) to the rod forming process such that the susceptor profile passes through at least the second stage. Further, the method includes separately passing the first substrate web and the second substrate web through the first stage. Thus, the first and second substrate webs are separately cross-directionally pre-assembled with respect to the respective direction of transport of each of the substrate webs through the first stage. The method further includes passing the susceptor shape and the pre-assembled substrate web through the second stage. Thus, the separately pre-assembled web of substrate fibers collectively gathers in rod-like form around the susceptor shape. The invention further relates to a multi-stage rod forming device (10) comprising at least a first stage (11) and a second stage (12) downstream of the first stage. The first stage is configured to separately pre-aggregate each of a first substrate web (31) and a second substrate web (32) as they pass through the first stage. The second stage is configured to collectively gather a pre-assembled substrate web into a rod-like shape around a susceptor profile (20) and the pre-assembled substrate web as they pass through the second stage.)
