arranging at least one pulling apparatus on the deep drawing model, wherein the pulling apparatus extends at least in sections between the deep drawing model and the deep drawing film and comprises a stop on the deep drawing model,
positioning the deep drawing model along with the deep drawing film over a removal opening, wherein an edge of the removal opening forms a stop limit for a free deep drawing edge of the deep drawing film, and then
bringing a movable puller into an engagement position in which the movable puller engages the stop of the pulling apparatus and moving the movable puller beyond the engagement position into a removal position; and
pulling the deep drawing model out of the deep drawing film through the removal opening.
