A method for preparing extruded material for processing to form sealings and/or edge protection strips on vehicle bodies, where the extruded material to be prepared, which is substantially of an elastomer substance, includes a covering strip protecting an adhesive layer and extending in the longitudinal direction of the extruded material. The covering strip has sub-sections that are connected to each other on the abutment ends thereof. The covering strips are detached from the adhesive layer and are reconnected to the adhesive layer, optionally in such a way that they are offset to the longitudinal direction of the extruded material. If the offsetting is carried out, the abutment ends of the sub-sections of the covering strip are arranged such that they are offset in relation to the original position thereof on the adhesive layer.
