The invention relates to a method for producing sealing rings open to the outside or to the inside, which method comprises the steps of providing a tube, arranging the wall of the tube between at least one first roller that is parallel to the tube and has a first outside contour, and at least one second roller that is parallel to the tube and has a second outside contour; carrying out a relative movement of the at least one first roller and the at least one second roller towards each other; forming at least one sealing ring by a relative movement of the wall of the tube between the at least one first roller and the at least one second roller, wherein the cross-section of the at least one sealing ring is defined substantially by the space between the first and second outside contours; and severing the at least one sealing ring from the tube. The invention also relates to a device for carrying out the method and to a selling ring produced in said manner. |
