生产密封环的方法及设备
摘要：
本发明涉及生产对外开口或对内开口的密封环的方法，该方法包括以下步骤：提供管子（2）；将管子（2）的壁设置在至少一个第一辊（4）和至少一个第二辊（6）之间，第一辊与管子（2）平行且具有第一外轮廓，第二辊与管子（2）平行且具有第二外轮廓；使至少一个第一辊（4）和至少一个第二辊（6）朝向彼此做相对运动；通过管子（2）的壁在至少一个第一辊（4）和至少一个第二辊（6）间的相对运动使至少一个密封环成型，其中，大致上由第一外轮廓与第二外轮廓间的空间限定至少一个密封环的横截面；以及使至少一个密封环与管子（2）分离。本发明还涉及实施该方法的设备、以及涉及以所述方式生产的密封环。
摘要（英）：

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.
