A roller forming device and method for forming a material provided with geometric elements, in particular holes, is disclosed. The device has at least one forming roller and at least one counter roller, wherein a roll gap is configured between the forming roller and the counter roller for carrying through the material. The forming roller has a molding structure on its cylindrical surface, which molds the material when the material runs through the roll gap. The forming roller has carrier elements for an engagement with the geometric elements of the material running through the roll gap.
