Abstract (en)

[origin: WO2011141190A1] 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 (2), arranging the wall of the tube (2) between at least one first roller (4) that is parallel to the tube (2) and has a first outside contour, and at least one second roller (6) that is parallel to the tube (2) and has a second outside contour; carrying out a relative movement of the at least one first roller (4) and the at least one second roller (6) towards each other; forming at least one sealing ring by a relative movement of the wall of the tube (2) between the at least one first roller (4) and the at least one second roller (6), 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 (2). The invention also relates to a device for carrying out the method and to a sealing ring produced in said manner.
